EP 22 - What's That Smell? Is it Disrupting My Hormones?

Fungi are everywhere, and I mean EVERYWHERE. And they tend to be pretty misunderstood. Yeast, mold, and mushrooms are not plants, not bacteria, and not just spooky Halloween germs. They are a completely different branch of life, and they play a much bigger role in your environment, your skin, and your cosmetics than you probably realize. This week we break down what it means to be a fungus in a way that finally makes sense, from the cell-wall secret ingredient that separates them from bacteria and plants to the digestive reason they can be both helpful and harmful. This episode also gets into one of the strangest and most useful parts of fungi - their byproducts. From ancient moldy-bread medicine to modern ingredients like citric acid, azelaic acid, beta carotene, and fermented squalane, fungi show up everywhere once you know what to look for. If you care about skincare, cosmetic preservation, microbiomes, or just want to stop side-eyeing mushrooms every time they pop up on your feed, or in your lawn, this one is for you. Perfect for anyone with a little mycophobia, a lot of curiosity, or a growing obsession with the science behind beauty products. By the end, fungi may still seem weird - but they’ll make a whole lot more sense. We are chatting about: Why fungi are similar to humans What chitin is and why it matters in fungal cell walls The difference between yeasts, molds, and mushrooms How fungi help decompose matter and recycle nutrients Why your skin microbiome includes both bacteria and fungi The real risks behind fungal infections like athlete’s foot, ringworm, and fungal acne How cosmetics get contaminated, and how GMP and preservatives help prevent it Which fungal-derived ingredients show up in skincare, including snow mushroom, reishi, shiitake, chaga, cordyceps, and more Welcome to Beauty by the Beaker, the podcast where Sciences Gets a Hot New Makeover!

Have you heard of Zombie Cells? Senescent cells are real, but the skincare claims built around them are often way more terrifying than the science supports. This week in the Science Salon, Sadie and Nat unpack the spooky truth behind these dormant skin cells. The scariest thing might be all the new vocab words. This week we discuss telomeres and apoptosis and explain how UV damage and stress fit into the story. You’ll hear how certain ingredients are being sold as senolytics, and why the jump from petri dish results to real-world skin benefits is a much bigger leap than brands want you to think. This week we help you understand why these “zombie cells” are suddenly everywhere in anti-aging marketing. We also dig into the products making the loudest promises like Peach and Lily’s Zombie Cream featuring DSM’s Eterwell™ Youth. We dive into the studies, including the in vitro, ex vivo, and human data behind the ingredient claims. We press on the details that matter most: sample size, placebo controls, concentration, and whether the marketing is really about science or just smart wording. The conversation also gets into why hydration ingredients like glycerin may be doing more of the visible heavy lifting than the “zombie cell” story. We are chatting about: Why senescent cells are called zombie cells How telomeres and cellular damage push skin cells toward senescence or apoptosis What DSM claims about targeted apoptosis and collagen support Where the evidence is strong, where it gets fuzzy, and where brand marketing starts to overreach Why a $435 serum with a confusing ingredient deck is not automatically worth your money Welcome to Beauty by the Beaker, the podcast where Sciences Gets a Hot New Makeover!

We are kicking off Spooky Season the scariest way we know how! Beauty misinformation is more than annoying, it shapes what people buy, believe, and do with their skin. In this episode, Sadie and Nat break down some of the most persistent beauty myths, from chemical sunscreen fears and “reef-safe” claims to oral sunscreen supplements, preservative misinformation, and the ways AI and sensational headlines can distort scientific evidence.The hosts recap the Truth and Beauty eSummit from The Eco Well, exploring how emotional marketing, cherry-picked studies, and the attention economy help beauty misinformation spread. They discuss why chemical sunscreens are often unfairly villainized, why sunscreen supplements probably aren’t the safer shortcut they sound like, and why “reef-safe” is more of an unregulated marketing claim and less of a scientific guarantee.From sunscreen myths to fear-based beauty marketing, this conversation looks at the real-world consequences of misinformation and offers a more thoughtful way to evaluate skincare claims. If you’re interested in skincare, cosmetic chemistry, sunscreen, or making sense of beauty science, this episode is for you.Grab a seat, we are chatting about: The Importance of Science CommunicationThe financial problem behind beauty researchWhy the term “chemical sunscreen” can sound scarier than the evidence suggestsWhat to consider when evaluating sunscreen claimsWhy sunscreen and coral reef headlines can leave out important contextHow AI search results can amplify low-quality or misleading scienceWhy preservatives matter for cosmetic safetyHow science, art, and aspiration shape the beauty marketQuestions to ask when deciding who to trust, and what they might gain from your beliefThe importance of source vettingWelcome to Beauty by the Beaker, the podcast where Sciences Gets a Hot New Makeover!

This week is all about scalp health. Your itchy, flaky scalp might not be dandruff, and using the wrong treatment could make it worse. In this episode of Beauty by the Beaker, cosmetic chemists Sadie and Natalie explain the difference between dry scalp, dandruff, seborrheic dermatitis, and psoriasis, plus how to choose a smarter next step. Learn how scalp oil, aka sebum, and the yeast Malassezia are connected to dandruff and why itching can start before flakes appear. Not all scalp issues are microbial, and this week we discuss how clues like flake texture, redness, your environment, and hair-washing habits may help you understand what’s going on. What makes this distinction important? We explain why dry scalp and dandruff typically call for opposite approaches. This episode covers the scalp microbiome (and its limited research), over-the-counter dandruff shampoo ingredients, and how treatments such as pyrithione zinc, salicylic acid, selenium sulfide, sulfur, and ketoconazole work. Find out why some ingredients target fungal overgrowth while others help loosen and break up flakes. Learn how to properly use these products, and why letting dandruff shampoo sit on your scalp for a few minutes can matter. If you’re wondering whether to use a gentle hydrating shampoo, an anti-dandruff treatment, or scalp oil, this practical scalp-care guide can help you avoid common mistakes. Understand when cautious trial and error may be reasonable and when it’s best to see a dermatologist. Remember if your scalp is painful, very inflamed, or symptoms are spreading, it’s best to skip the headache and see a professional for a diagnosis.

Every once in a while we see pH marketed on labels, but most people have no idea what it actually means - and that confusion is exactly why it has the opportunity to become such a powerful buzzword. If you’ve ever wondered whether “pH balanced” skincare or hair care is worth paying more for, this episode breaks down the science in a way that finally makes sense. This week we are discussing the power of Hydrogen, and we are doing it in some very conceptual and possibly less than scientific ways. We explain what the pH is, what the scale is based on, and how a tiny shift can represent a 10x change in hydrogen ion concentration. That definitely matters as a chemist when we are formulating products that touch your skin, hair, or scalp, but does it matter as a consumer?
