We are two cosmetic chemists, and in this mini episode we are chatting all about one particular TikTok it-girl, and her highly anticipated new skincare line. Of course we are going to be addressing all the controversy. There is at least one thing that Sadie, Natalie, and Alix all have in common, and thats a history with Isotretinoin (Accutaine), and we are diving into the ethics of creating and marketing cosmetics aimed at acne prone skin while not being transparent about your how you achieved your own results. 

But beyond perfect skin, we are talking about how brands use selective marketing terms to avoid conflict with the FDA. We are 'clearing up' some of the clever ways that heavy marketing implications keep brands "Free-from"OTC claims. Like what does Breaking Out Free actually mean? 

And while we dont think an 8% Mandelic Acid serum is the silver bullet to clearing cystic acne, we discuss the tricky situation that brands are put into when it comes to balancing innovation and medical claims.

And while the packaging is super cute, you can't trick us into paying $36 for 2oz of product. Do we think this is just a cash grab? Or should women be allowed to start businesses that align with their personal brand without being questioned? Find out Now!  

Products Mentioned: 

GoDeep Serum ($39): Marketing ingredients - 8% Mandelic Acid

Pore Power Cleanser ($28): Marketing ingredients - LHA & BHA

Barrier Boosting Moisturizer ($36): Marketing ingredients - Shea Butter & Ceramides

Makeup Melting Balm ($30): Marketing ingredients - Lipid-rich emollients

This week we are jumping into a highly requested topic - synthetic food dyes. But in order to really answer the question - Do we need to fear Red 40 - we first need to go over some of the history of Dyes. It turns out humans love colors, and we have for as long as we have been around. We talk about the first synthetic dye, mauvine, which was made on accident when an 18 year old chemist was trying to make medicine out of coal tar. We also talk about the first synthetic pigment, which was a much earlier - Egyptian Blue. We are discussing the history of synthetic dyes in food. And talking about the specific reasons why Red gets so much hate. We are talking about some of the big color events that shook the food industry and led to the banning of Orange 1, Red 2. And the more recent controversy surrounding red 3. Plus we are addressing some of the common claims around synthetic dyes and reminding you that natural doesn't always equal better.

Forget everything you thought you knew about surfactants, this week we are talking about the most common cleansing myths. We answer - if my cleanser is burning, does that mean it's working? Does your shampoo open and close your hair cuticle? Do rinse off products even matter? Spoiler, they do. They are actually designed to be rinsed off, and we are talking about why. We are talking about the science behind double shampooing, and why you get so much foam the second time. We’re ending the episode with a conversation about Natural vs Synthetic, and how natural doesn’t always mean better, or anything at all. Most importantly, we are reminding you of the complexities of surfactant systems, and why you can’t really judge a cleanser based on its ingredient list.

We are back in the Science Salon, and we are ready to chat more about our favorite unifiers. This week we debrief from the chemistry lesson we had on the 4 types of surfactants. We are talking about color safe shampoo, and how sulfates got such a bad reputation. Then we are talking about a familiar grapefruit acne facewash, and different types of makeup removing methods. This one is all over the place, so try to follow along!

Additional notes from todays episode: We mention Anionic Surfactants are petroleum derived (crude oil), but they can also be coconut/palm derived. This is a whole different ethics question. The Microbead-free waters act of 2015 - prohibited the use of plastic microbeads in the use of rinse off products. The deadline for the change was 2017.

Products Mentioned in the Episode:

Neutrogena Oil-Free Acne Wash Pink Grapefruit Facial Cleanser ($8)

Neutrogena Makeup Remover Cleansing Towlettes ($8)

Its Wednesday again! Welcome back to the Science Salon for another episode of Beauty by the Beaker.

Welcome back to another episode, and the first of many on Natural vs. Synthetic cosmetic ingredients. This week, we’re talking all about what “natural” actually means (spoiler: the FDA doesn’t even know). We discuss why petroleum might be more natural than you think, and why nature — beautiful as she is — definitely does not have our best interests in mind.

The goal here isn’t to make you scared of your skincare, but to help you feel more confident and informed when you’re picking your cosmetics. After all, it is PERSONAL care.

Is the guy in the logo real? In our first solo mini episode, we are going to deep dive into the story behind the brand, Burt's Bees. Burt Shavitz wasn't looking for fame, so how did he go from a self described loner to arguably the most famous bee keeper in the world? It started when a 60s hippie left his life as a street photographer for Time-Life in Manhattan. Burt describes getting his hives as divine intervention, and started selling honey from his truck. In another turn of fate, he met a woman who would take his sweet and small operation to a 900 million dollar personal care company, Roxanne Quimby.

Although today cosmetics are the brands sole focus, that certainly wasn't where this started. So what is the real story? Was it a love affair, a dynamic duo, or complete exploitation? We do our best to uncover it.

In this episode we are talking about the burts, so we needed to cover the bees. What makes the honey bee so important? We are talking about different types of bees, and how honey and beeswax are made. Is honey just bee vomit? And did this insect invent the worlds first plastic?

***PLEASE READ BEFORE ANY PUMPKIN DIY - please use caution if trying pumpkin in cosmetics. Pumpkin is not preserved, and is NOT shelf stable. Do not add pumpkin to existing cosmetics unless intended for immediate use. There are many pumpkin DIY recipes online, some say they are shelf stable, but they are NOT. Unpreserved cosmetics are dangerous.

In this episode of Beauty by the Beaker, hosts Sadie and Nat are diving into one of the most misunderstood topics in beauty — parabens and preservatives. We get into how parabens have been used safely for so long, when they got such a bad rep, and why some of the so-called “clean” alternatives might not be any better. We talk about the Darbre study that started all the drama around parabens (and why it’s actually pretty flawed), plus what “hazard vs. risk” really means.

From lead-based face creams to donkey milk exfoliants and even gladiator sweat, skincare has always been a mix of ritual, culture, science, and risk. In this episode, we chatted about the strange and surprising history of beauty, from ancient Egypt and Rome to today’s TikTok trends, and discovered what it reveals about gender, class, colonialism, and medicine.

This week we are putting an end to greenwashing in cosmetics! (If only it was that easy) 

Welcome to Beauty by the Beaker, the podcast where Sciences Gets a Hot New Makeover! We're two cosmetic chemists who want to reveal what really goes into your favorite products, and we aren't afraid to bust some myths while doing it. Whether you’re a skincare enthusiast, a curious consumer, or just tired of being told coconut oil cures everything, you’re in the right place. Let's gossip about all things beauty together! Pull up a chair, your appointment's about to start

CHAPTERS

00:00: Catching up about being the luckiest girls in the world

05.59: Greenwashing! What is it? Who is doing it? Who does it affect? Breaking down some of the sneaky marketing tricks that companies use to make their cosmetic products seem better for the environment than they actually are. We are going over the 7 sins.

09:40: Sin 1, the Sin of The Hidden Trade Off. The company might be making small efforts that appear to be sustainable - is this a positive solution, or a distraction to a larger problem?  

13:59: Sin 2, the Sin of No Proof. Companies who make claims about their sustainability efforts, but don’t have the receipts. Discussing future washing, and one very big example of greenwashing: reef safe sunscreen. We hate to break it to you, but switching to mineral sunscreen isn’t going to save our coral. 

19:32: Sin 3, the Sin of Vagueness. You have probably heard of ‘clean beauty’ but what does clean even mean? Turns out, companies have found a lot of wording loopholes to market their products, and if you can’t define something you can’t deny it either. This strategy relies on consumer confusion, and allows companies to benefit from association without actually doing anything. Boo

24:04: Sin 4, the Sin of Irrelevance. This is kind of like companies giving themselves participation awards and we see it all the time. Paraben Free? Good for you! So is everyone else (mostly, and unfortunately)!  So this is when a brand will say things just to say them, does it have anything to do with their product? No. 

27:31: Sin 5, the Sin of the Lesser of Two Evils. Some things are just inherently bad. Luckily you guys are smart, so this strategy isn’t very successful. 

29:24: Sin 6, the Sin of Fibbing. This one is illegal. So it's also not common, especially in the states, because we like to sue.   

30:27: Bonus Sin 7, the Sin of Worshiping False Labels. Everything looks great from the packaging, but that's as deep as it gets.

32:17: Brownwashing, or Greenhushing. These strategies aren’t new, and consumers are already recognizing them. If they spot ‘greenwashing’ this can cause distrust in the brand. Have you ever questioned the motives behind a ‘kind’ act? This added layer of confusion doesn’t make finding environmentally conscious brands any easier. 

39:32 Combating Greenwashing: We talk about how consumers can challenge greenwashing, and have a positive impact on the earth. Micro vs macro impact, which is really important to recognize if we ever want to make a difference. Buying new things is a net negative, so the best we can do is learn to be conscious consumers! Everyone has a small improvement they can make, and a small effort from a large group of people will go a long way.

Welcome back to another Wednesday! This week we are giggling about gold. This beautiful metal has been popular throughout all of history, but why is that? In this episode we are explaining the science behind this unique material. Its variety of uses range from traditional medicine to jewelry, but does it have potential to be a skincare miracle worker? We are discussing nanoparticles, and how gold can be complexed with beneficial active ingredients - but not all that glitters is gold. Pull up a chair and laugh along with us.

SHOW NOTES

03:15: Catch up: Talking about birthdays, Valentines Day, Wuthering Heights. We get a little personal about holiday expectations, and decide once again that our differences make us great! 

08:02: Important Podcast News updates! This show is still self funded, you can contribute by liking, subscribing, commenting, and if you are feeling extra generous, sharing the episode. 

10:45: The history of gold, how it's been used in cosmetics, and whether or not it is the anti-aging miracle some people claim it to be.  We give a big disclaimer for this episode, which is that it's going to be a fun one, so maybe don’t take it too seriously. 

12:14: Gold in Ancient Egypt. HThis segment is a bit hard to follow, so we we hope you are also the luckiest girl (or anyone) in the world, you’ll need it. 

17:10: Gold in Medicine: Traditional holistic medicine, originating in India and Nepal, Ayurveda, uses a gold preparation called Swarna Bhasma. This is intended to be ingested, which despite some marketing claims, is different than putting it on your skin. 

18:55: What are Nanoparticles? We are talking about some scientific advancements, and a couple not-so-scientific ones too. When it comes to active ingredients, size matters, particle size that is. And the smaller the thing, the more likely it is to pass through you, and like with all science, it's not all good or bad. 

20:45: Why do humans love gold? We are discussing this element's unique properties, and how those make it such a great material for jewelry, but also safe to eat.

24:40 Surface Plasmon Resonance, and why it makes very small particles of gold appear red or purple. We got off topic pretty quickly though. 

27:07 Properties of Gold nanoparticles make them interesting for Biomedical Research, but are they useful in skincare? High-end Gold-infused skincare. 

28:21: Is Using Gold Skincare Safe? Why it's hard to study the efficacy of gold nanoparticles. 

30:08: Revealing the secret to anti-aging. **disclaimer - lots of joking in this section. 

31:39: Humans love Gold. That's why we typically give gold to the ones we love - in the form of a wedding ring! All jokes aside: 14k is the ‘gold standard’ when it comes to jewelry. 

32:43: It's getting late, and things are starting to get extra silly. 

34:25: Gold symbolizes exclusivity. Weird, humans have always been super logical when it comes to luxury. We conclude that gold is super fun to look at, but when it comes to fixing your skin issues, your money might be better used on a more scientifically backed ingredient. 

36:43: Teasing this month's episodes, and a gold product we are both loving. 

We have spent all month talking about smells, but how do perfumes even work? And what makes them all smell so different? In this week's episode we are explaining some perfume basics, like what is the difference between cologne and an eau de toilette? We are talking about fragrance ingredients, and the important roles that they play in finished perfumes. Plus, we are telling you what perfume bottles you are likely to find on each of our shelves, and the scent notes that are inside. Of course, since Natalie and Sadie don’t necessarily sniff nose-to-nose, we end with a reminder that fragrance is truly so personal.

This week we are back in the Salon to talk about a special type of chemical that MIGHT help you find your Valentine, Pheromones! Which as you may have guessed, are linked to some debatable science. We are discussing some well known examples of animals who use pheromones, and then talking about why humans probably don't. Even if we don’t use our noses to find love, we are talking all about how our sense of smell influences our decision making.

Pheromones are very well studied  in the Silkworm, which does in fact grow up to become a silk moth.

We talk about how humans actually do use Pheromones, just not with their Jacobsons Organ. We use them to protect crops from pests. Research on pheromones started in the 1950s, and they were originally used by farmers to lure in insects and trap them. In the 1970s, they started using them as a way to prevent mating success, which decreased the population.

Chances are, you probably have some sort of fragrance in your going out routine, whether its a scented lotion, body spray, deodorant, or perfume. For many of us, the way we smell is in some way tied to our identity, but this isn't new. Humans have been using fragrance oils and perfumes for basically as long as we have been around. Today we are diving into the weird history of perfume. From Egyptian head cones to Chanel no. 5 and Creed Aventus, we are learning how scent has shaped our society.

PDRN is the trending skincare ingredient derived from salmon sperm that promises rapid skin repair. Is all the hype justified, or is it just another trendy ingredient with little scientific backing? Before you decide to spend your money on PDRN, this episode is a must-listen.We are Sadie and Natalie, two cosmetic chemists who love to chat. This week we are pulling back the curtain on PDRN’s fishy origins. You’ll discover the biggest hurdle when formulating with this ingredient, size limitations of molecules, and whether it truly penetrates the skin or just sits on the surface. We are breaking down the difference between topical and injectable studies, reveal why most of the science so far is weak, and question whether the ingredient is as miraculous as marketing suggests.We cover the ‘evidence’ that makes PDRN a perfect example of the “miracle ingredient” trap. Touting claims that it heals wounds, supports DNA repair, and rejuvenates skin without solid evidence. You'll learn what the real science says about skin penetration, whether plant-based PDRN is a marketing gimmick, and what ingredients are actually doing the heavy lifting in those luxury serums. Plus, get the inside scoop on why this salmon-derived component may be more wasteful than sustainable, and whether current regulations are actually protecting consumers, or just letting false claims slide.Essential listening for skincare enthusiasts, trend skeptics, or anyone tired of miracle marketing. If you're questioning the true value of the latest trend, this episode will help you cut through the hype with science-backed insights and honest analysis. Should you run from PDRN or explore its potential? Tune in to find out, and decide for yourself.Curious about how much of what you’re told about skincare ingredients is marketing magic? This episode is your guide to navigating the murky waters of beauty claims, and whether PDRN deserves a place in your routine. Get ready to rethink what “regenerative” really means, and discover what science (and common sense) have to say about this trendy ingredient.Welcome to Beauty by the Beaker, the podcast where Sciences Gets a Hot New Makeover!

0:00 - Introduction to Looksmaxxing 

Discussion on the concept and its societal implications.

15:18 - A Never Ending Pursuit For Perfection

How looksmaxxing has roots in historical beauty practices.

19:06 - Modern Trends and Influences 

The role of social media and influencers in popularizing looksmaxxing.

21:35 - Gender Perspectives 

Differences in beauty standards and expectations for men and women.

25:14 - Psychological and Social Impacts

How looksmaxxing affects self-esteem and social interactions.

28:31 - Ethical Considerations 

The dangers and ethical concerns surrounding extreme beauty practices.

29:37 - Conclusion and Personal Reflections 

Final thoughts on the future of beauty standards and personal empowerment.

This week we are diving into a HOT topic - Looksmaxxing. Most of society can agree that appearance ISN’T everything, but why haven’t we ever been able to move past the importance of our looks? and why are straight men suddenly going to such dangerous lengths to maxximize their appearance? In this provocative episode, we unravel the (not so) surprising parallels between gendered beauty practices and the extreme phenomenon of looksmaxxing among men, from steroid injections to bone smashing. Is this just a new twist on a tale as old as time?

Join us in the Science Salon, and discover how the desire for societal acceptance fuels this dangerous trend and why mainstream media, social media, and even medical professionals play a role in pushing these extreme practices. We break down the origins of looks maxxing, revealing how a 2010s niche internet phenomenon has become a mainstream obsession. We explore the impact of black pill ideology, where appearance is seen as the only way to social mobility, and why society's system of beauty standards needs urgent reevaluation.

We analyze real examples like Braden Peters, better known as  "Clavicular", the TikTok star injecting steroids and smashing his jaw, and examine how younger generations are risking their health in pursuit of perfection. We are talking about the dangerous extremes like plastic surgery, illegal drugs, and body modifications that are widely normalized in the beauty industry, even if they are inherently reckless. 

Beyond the shock factor, this episode challenges you to think about the systemic pressures behind looksmaxxing. Is this merely individual vanity, or are we all complicit in a system that prizes superficial beauty over genuine confidence? We consider how media, societal expectations, and gender stereotypes shape this obsession, and what we can do to foster self-love and confidence outside of appearance.

At the end of the day, the non stop pursuit of perfection is in vain. Remember to love each other, and look for ways to help people out. BXB welcomes all, no matter their physical appearance.

Flawless: Lessons in Looks and Culture from the K-Beauty Capital - Elise Hue

We are unlocking the secret differences between makeup and skincare formulations and discover why most companies excel in one, but not both. 

Cosmetic chemists Sadie and Natalie pull back the curtain on how the beauty industry structures its product development, from the complex web of outsourcing to the specialized labs that craft your favorite products. They explore the vast “umbrella” of cosmetics, breaking down why makeup (color cosmetics) require such painstaking precision, and how formulating a lipstick or foundation is a whole different ballgame from creating a serum or night cream. You'll learn about the intricacies of color matching, the high cost of pigments, and our opinion on why darker shades may be less common. 

Listen to this episode now and discover: 

How the cosmetic industry separates color cosmetics from skincare and why they’re often produced at different facilities

The specialized skill sets required to craft liquids, solids, powders, and aerosols, and why not every lab can do it all

Why color accuracy in makeup is so critical, and how formulation impacts everything from shade range to product stability

The role of active ingredients and how their concentration impacts efficacy, compared to the immediate visual impact of color cosmetics

The hidden costs behind pigment selection and why darker shades tend to be more expensive to produce

How FDA regulations influence color choices and ingredient options in the US market

This episode is perfect for beauty lovers, aspiring formulators, or anyone curious about what goes into the products they use every day. Get a crash course in the science that makes makeup vibrant and skincare effective, and understand why some products are more complex (and costlier) than they appear on the surface.

Are you brushing your teeth with explosives? No, not really, but your cosmetics could still set off alarms going through TSA, and not just because they are bigger than 3.4oz. In this episode we are diving into a cosmetic ingredient that might help with tooth sensitivity, but it might also get you stuck at the airport security checkpoint having your luggage swabbed. Potassium Nitrate, KNO3. In this episode we are diving into some of the primary uses of Potassium Nitrate. We are covering fertilizers, fireworks and filet mignon (meat preservation), and how the oxygen present in nitrates makes it helpful for many everyday uses. Then we are talking about its use in cosmetics. If you have ever used a toothpaste designed to reduce sensitivity, then you have used this ingredient. We are covering how sensitivity relief toothpaste works, and the studies that have proven it to be effective (and of course, poking some holes in them). It's always important to remember that the same ingredient can be used in multiple applications, and will perform differently in each of them. If there is an ingredient in common with fertilizer and your toothpaste, that does NOT mean you have fertilizer in your toothpaste.

Do you know truth behind terms like "non-comedogenic"? Most skincare claims are based on estimates and outdated science, 

In this eye-opening episode, cosmetic chemists Sadie and Natalie reveal the hidden flaws in skincare labeling, and why "non-comedogenic" means little without proper evidence, and how marketing exploits consumer fears.

If you have shopped for cosmetics you have probably come across the term non comedogenic, but what does that really mean? In this episode we are talking all about what it actually takes to be permitted to legally use the words non comedogenic on your product, shockingly its not much. We are introducing a new more robust term, acnegenic, which tells us more about the likelyhood of a clogged pore actually leading to acne.  We are also talking about some different ways that you can find products that work well with your skin and don't break you out. 

In this Episode we cover: 

Why the term "non-comedogenic" is virtually unregulated and how companies often label products without rigorous testing

The differences between non-comedogenic, non-acnegenic, and their relevance for acne-prone skin

How current testing methods like rabbit ear studies and acne checkers often give misleading results

The truth about FDA regulations, recent legislation like MoCRA, and why most cosmetic claims are just marketing

Practical advice on patch testing, ingredient concentrations, and how to avoid pore-clogging ingredients without falling for buzzwords

Empower you to ask better questions and make smarter choices. Perfect for skincare enthusiasts, dermatology skeptics, and anyone navigating the confusing world of beauty marketing, this deep dive will have you questioning labels and understanding what truly matters when it comes to healthy skin.

Science is still learning, and skincare brands are often a few steps behind—don't be fooled by marketing. Arm yourself with knowledge and make decisions grounded in real science, not just buzzwords.

Most people believe certain ingredients or products cause acne, but the truth is far more complex, and surprisingly outdated. This week we are diving into the real science behind the popular non-comedogenic claim that’s been shaping skincare for over 50 years. This episode unpacks the origins of the Rabbit Ear Study, revealing why its findings are not super reliable. If you’ve ever read a label claiming “non-comedogenic” and wondered what it really means, this is your essential guide to understanding the truth about acne-causing ingredients, and spoiler: it's not what you think.

Sadie and Natalie, cosmetic chemists with over a decade of experience, break down the belief that certain ingredients block pores and cause breakouts. This idea was born in the 70s using animal testing. You’ll discover how early studies overstated the impact of individual ingredients, and why the finished product’s formulation, ingredient purity, and application hygiene matter far more than isolated components. We explore how modern science challenges the simplistic idea of “bad” ingredients, emphasizing that the overall formula matters, and not just one ingredient on a list.

Key Topics:

• The history and origins of the "non-comedogenic" claim, starting from the 1972 rabbit ear study by Albert Kligman and Otto Hills.

• The limitations and flaws of animal testing models, specifically how they overpredict comedogenicity compared to human skin.

• How formulations and the overall chemistry of a product impact its likelihood to cause breakouts, not just single ingredients.

• The myth that certain ingredients inherently cause acne, emphasizing the importance of dilution and formulation context.

• Insights into how modern studies and testing methods have evolved, including human trials and revisiting old assumptions.

• Why consumer-facing lists of "bad ingredients" oversimplify the complexity of skincare formulations.

• The influence of marketing, misleading claims, and the importance of understanding how products are tested and regulated.

How do we know which skincare ingredients actually work? Do cosmetics even work? Or are over the counter topical drugs the only way to reliably treat problem skin? In this discussion episode, hosts Natalie and Sadie reveal why some treatments are prescription-only while others are OTC, and why this matters more than you think. This week we are continuing our retinol conversation, and also revisiting some of our other recent topics like PDRN and Reale Actives, and explaining why cosmetic brands have no incentive to do good scientific studies. 

Discover how the FDA's outdated definitions make it tricky for brands to bring effective ingredients to market, and learn why some companies boldly blur the lines with ambitious claims. Uncover the real science behind retinoids, PDRN, and other active ingredients, debunking myths about strength, formulation, and regulation.

We are breaking down why tretinoin is prescription-only, but other retinoids aren't.

The complex dance between FDA definitions, bioavailability, and product efficacy, and why some ingredients get labeled as drugs while others stay in the cosmetic market, despite similar effects. We’re chatting about practical tips for choosing safer, more effective skincare, whether you’re a novice or seasoned professional. 

In a world flooded with confusing claims and fluctuating regulations, knowing the difference could save you time, money, and skin misery. This episode is perfect for anyone overwhelmed by skincare choices or curious about the real science behind the products you use daily.
