    Why Does Isotretinoin Work SO WELL? History and Controversy Behind Accutane - EP 40

    This week we are diving deep into Accutane, also known as isotretinoin. This is one of the most talked about acne treatments in dermatology. If you’ve ever wondered how Accutane works, why skin can get worse before it gets better, what the purge phase feels like, or whether Accutane is actually safe, this episode breaks it all down in a science-backed, easy-to-understand way. We cover the accidental discovery of Accutane, the history behind isotretinoin, how it targets sebaceous glands and oil production, and why it’s often considered a last-resort treatment for severe or stubborn acne. We also talk about common Accutane side effects like dry skin, dry lips, bloody noses, joint pain, vision changes, and increased breakouts during the purge phase. You’ll also learn about the iPledge system, the required pregnancy prevention program, the controversy around its new rollout, and the reasons dermatologists and patients have criticized it.  We are discussing the real-world experience of going on Accutane, as well as the emotional side of dealing with Acne. We talk about how to decide with a medical professional, how to determine the right time, if ever, to try this stuff out.  Whether you’re researching Accutane for yourself, comparing acne treatments, or just want to understand the science behind one of dermatology’s most effective medications, this episode is for you.

    Is Looksmaxxing The Answer To A Bigger Problem? - EP 38

    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.

    Avoid This Cosmetic Ingredient If You Are Going to the Airport - EP 34

    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. The concentration and the other ingredients in the formula are always going to be more important than any one ingredient (Unless you are have an allergy) Welcome to Beauty by the Beaker, the podcast where Sciences Gets a Hot New Makeover!

    EP 33 - How to REALLY find Acne Safe Skincare.

    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.
