Which skincare should you use when acne is treated with lasers, IPL, photodynamic therapy (PDT), or microneedling? Board-certified dermatologist Dr. Ted Lain is in Paris at the L'Oréal Skin Alliance conference with Dr. Cheng-Feng Zhang, Professor of Dermatology at Huashan Hospital, Fudan University in Shanghai. Dr. Zhang is an expert in acne, pigmentary disorders, and cosmetic dermatology. Both doctors helped write a new international consensus paper: a practical algorithm for combining skincare with energy-based devices (EBDs) for acne. It was published in February 2026 in the Journal of Drugs in Dermatology (JDD), and Dr. Jill Waibel is the first author. In this episode they explain why the goal of acne treatment should be completely clear skin, and how prescription therapy, in-office procedures, and a good skincare routine work together to get there. In this episode: Why oxidative stress and reactive oxygen species (ROS) drive acne inflammation and acne scarringHow post-inflammatory erythema (PIE) and post-inflammatory hyperpigmentation (PIH) relate to acne scarsAntioxidant serums for acne-prone skin: silymarin, vitamin C (L-ascorbic acid), and ferulic acidWhy daily broad-spectrum sunscreen matters for acne patientsAcne and skin barrier dysfunction: ceramides, cholesterol, and fatty acids in moisturizersGentle, fragrance-free, non-comedogenic cleansers, and whether double cleansing makes senseEnergy-based devices for acne and acne scars: blue light, red light, IPL, PDT, pulsed dye laser, fractional laser, radiofrequency, and microneedlingWhen to stop retinoids before laser and light procedures, and when to start them againThis episode is sponsored by SkinCeuticals.

What started as a failed treatment for venous ulcers became one of the most influential products in professional skincare. Dr. Mitchel Goldman, co-founder of SkinMedica, tells the story of how TNS was created and why it was a "longevity" product decades before the term existed. Dr. Ted Lain sits down with Dr. Goldman, a world-renowned cosmetic dermatologist, former ASDS president, and director of cosmetic and laser surgery at Platinum Dermatology. Dr. Goldman shares how a passing comment from Dr. Richard Fitzpatrick about the skin around a wound led to the first growth factor serum. He also talks about the hard financial realities of building a skincare company and why physician-dispensed brands that invest in research stand apart. They also cover: Why the full "gemish" of growth factors, secretomes, and exosomes outperforms any single ingredientHow Dr. Goldman rotates growth factor products and lets patients' results guide the choicePre- and post-procedure skincare, and the shift toward priming fibroblasts with topical rapamycinWhether skin longevity needs multi-targeted or single-pathway productsDr. Goldman's personal cautionary tale about systemic anti-aging therapies, and why he favors topicalsHow a topical sodium bicarbonate made for athletes is now being studied in oncologyWhy aesthetic dermatology deserves a bigger place in residency trainingQuestions or ideas for future episodes?

Menopause is having a moment, but board-certified dermatologist and Menopause Society Certified Practitioner Dr. Corinne Erickson was connecting hormones and skin health long before it was trending. In this episode of the Science of Skin podcast, host Dr. Patti Farris talks with Dr. Erickson about how dermatologists can better care for women across the menopause continuum, from the first perimenopausal shifts to the postmenopausal years. Dr. Erickson explains her framework for making sense of the long list of concerns many women bring to the exam room, including hair loss, acne, unwanted facial hair, itching, sensitivity, and dryness. She traces them back to two key drivers: estrogen decline and relative androgen excess. The conversation covers what happens to collagen, hydration, and barrier function when estrogen drops, why vaginal estradiol belongs in the dermatologist's toolkit, what the evidence does and doesn't show about topical estrogen for facial aging and crepey skin, and how she approaches female pattern hair loss, including why she asks about hair at the start of every skin exam. She also introduces a new term she has proposed for dermatology: the Pilocutaneous Syndrome of Menopause (PSM). Like genitourinary syndrome of menopause and musculoskeletal syndrome of menopause, it gives clinicians and patients a shared name and a treatment framework grounded in the underlying hormonal changes.

Is there finally a fast-acting oral treatment for chronic hives? In this episode of the Science of Skin Podcast, board-certified dermatologist Dr. Ted Lain is joined by Dr. Naiem Issa, a dermatologist in Northern Virginia and assistant professor of dermatology at the University of Miami and George Washington University, to break down the phase 3 clinical trial results for Rhapsido (remibrutinib), the first oral BTK inhibitor for chronic spontaneous urticaria (CSU). Dr. Issa explains how Bruton's tyrosine kinase (BTK) inhibition works inside the mast cell to block the signals that lead to degranulation and histamine release, and why remibrutinib's covalent, highly selective binding helps explain its rapid onset and durable results. The doctors then walk through the pivotal trial data, including reductions in the Hives Severity Score (HSS7), Itch Severity Score (ISS7), and Urticaria Activity Score (UAS7). Patients saw about a 40% reduction in hives as early as week one, around 70% by week 12, and continued improvement through 52 weeks. Nearly 28% of patients reached UAS7 = 0, meaning complete absence of hives and itch, at week 12 compared with 6.5% on placebo, rising to almost 46% at one year. They also discuss the challenging trial population, which included patients with severe disease uncontrolled on up to four times the standard dose of second-generation antihistamines, many with angioedema, and about a third with prior anti-IgE biologic therapy such as omalizumab. Dr. Lain and Dr. Issa cover angioedema-free weeks, what complete control means for quality of life, how this data may change CSU treatment for dermatologists and allergists, and what new data on even faster onset may be coming soon.

Can a topical serum work like a neurotoxin? Recorded live in Paris, Dr. Ted Lain sits down with Dr. Peter Bjerring to find out. Dr. Bjerring is a professor of dermatology at Aalborg University Hospital in Denmark, a laser pioneer who helped develop IPL technology, and a Knight of the Order of the Dannebrog. Together they break down SkinCeuticals P-TIOX, a serum built around two viper-venom-derived neuropeptides. One acts presynaptically, like botulinum toxin. The other blocks acetylcholine receptors on the muscle side. Both are small enough to penetrate the skin, which injectable toxins can't do. Dr. Bjerring walks through two of his clinical studies. In a split-forehead sweat study using the Minor iodine-starch test, the treated side showed little to no sweating after just three applications. That suggests the peptides really do reach their targets in the skin. In an 8-week, all-male study of 36 participants across multiple ethnicities, twice-daily use reduced forehead and glabellar lines by about 15%. Crow's feet, nasolabial folds, and even marionette lines also improved, and results kept getting better between weeks 4 and 8. The conversation also covers the supporting ingredients: 5% polyhydroxy acid for gentle exfoliation, niacinamide for barrier support, tone, and redness, and Laminaria digitata for antioxidant and collagen support. They discuss why so many self-reported sensitive-skin participants had no irritation, and how P-TIOX may pair with injectable neurotoxins to target the fine, superficial texture lines that injections miss.

In this episode of the Science of Skin Podcast, Dr. Ted Lain talks with Dr. Rich Miller, professor of pathology at the University of Michigan and director of the Paul F. Glenn Center for Aging Research, about the science of slowing biological aging. Dr. Miller explains why lifespan and health span move together, not in opposition, and walks through decades of research using genetic mutants, calorie-restricted diets, and drugs like rapamycin, acarbose, canagliflozin, and 17 alpha-estradiol to extend lifespan in mice. The conversation covers how these interventions work through pathways like mTOR and glucose regulation, why some drugs affect males and females differently, and the surprising finding that many of these anti-aging effects hold up even when treatment starts in middle age rather than early in life. The two also discuss the challenge of translating mouse research to humans, Dr. Miller's work developing "aging rate indicators" that could make human drug trials for aging far more practical, and his call for more dermatology involvement in aging research — including his hope to see skin aging studied alongside the organs his lab has already examined. The episode closes with a candid take on supplement industry claims and what the current evidence actually supports for slowing aging today. ⚠️ This content is for educational and informational purposes only and reflects the personal research findings and opinions of the speakers.

In this episode of the Science of Skin Podcast, Dr. Ted Lain sits down with Dr. Sarina Elmariah, MD, PhD, professor of dermatology at UC San Francisco and director of the UCSF Center for Itch and Neurosensory Disorders, for a deep dive into chronic spontaneous urticaria (CSU). Dr. Elmariah breaks down the role of Bruton's tyrosine kinase (BTK) in mast cell degranulation and explains how it sits at the center of the histamine release cascade. The conversation covers the difference between Type I (auto-allergic) and Type IIb (autoimmune) CSU pathways, available diagnostic tools like autologous serum skin testing and basophil activation testing, and why BTK appears to be a common thread across nearly all CSU mechanisms — including many inducible urticarias. The two also discuss remibrutinib (brand name Rhapsido), a BTK inhibitor newly FDA-approved for CSU, and what makes its binding mechanism distinct from earlier BTK inhibitors. They close with a look beyond histamine at the other inflammatory mediators — proteases, leukotrienes, prostaglandins, and cytokines — that help explain why so many CSU patients don't respond to antihistamines alone, and why angioedema tends to linger longer than a typical urticarial wheel.

Korean skincare is everywhere on social media — but how much of it is backed by real dermatologic science? In this episode of The Science of Skin Podcast, Dr. Patti Farris sits down with Dr. Jane Yoo, board-certified dermatologist, fellowship-trained Mohs surgeon, and "The K-Beauty Dermatologist," to separate fact from TikTok fiction. They trace K-beauty's roots from the Goryeo and Joseon dynasties through the Hallyu wave, then dig into the science: ceramide-dominant, barrier-centric formulations, low-pH cleansers, and why "glass skin" is more about consistent barrier care (and good lighting) than any single product. Dr. Yoo also breaks down the real evidence behind snail mucin, PDRN and PN, exosomes, and silica spicules — including where the hype outpaces the data — plus whether double cleansing is really necessary and why Korean sunscreen filters like bemotrizinol (Tinosorb S) may be the biggest public health advance in photoprotection in 25 years. In this episode: The real history of K-beauty, from royal court rituals to global export What actually causes "glass skin" (and what doesn't) The truth about snail mucin, PDRN/PN, exosomes, and spicules Do you really need to double cleanse? Why newly approved filters like bemotrizinol could change US sunscreens Tinted, visible-light-blocking sunscreens for skin of color Have a question or an idea for a future episode?

In this special bonus episode of the Science of Skin Podcast, Dr. Patti Farris sits down with Dr. Sandra (Sandy) Johnson — private practice dermatologist in Fort Smith, Arkansas, and member of the American Academy of Dermatology's Board of Directors — for an urgent conversation on the CMS reimbursement cuts threatening the future of dermatology. Dr. Johnson breaks down the three major proposals from CMS that could devastate dermatology practices nationwide: a proposed cut to the 25-modifier that would penalize combined evaluation-and-procedure visits, a potential overhaul of indirect practice expense calculations that could hit dermatology harder than most specialties, and an effort to remove the AMA's RUC representation — stripping physicians of their voice in how reimbursement values are set. Beyond the policy breakdown, Dr. Johnson shares what the AAD is doing to fight back and exactly what members can do right now: submitting the 30-second advocacy letter through Voter Voice, rallying staff and patients to do the same, donating to SkinPAC, and attending this year's Legislative Conference in Washington, DC before the mid-September deadline. This is a call to action for the entire dermatology community — because a united voice is the specialty's best defense. Topics covered: The proposed 9–25% CMS reimbursement cutsThe 25-modifier and what it means for combined visitsIndirect practice expenses and why dermatology may be hit hardestEfforts to remove the AMA from the RUCHow to take action: Voter Voice, SkinPAC, and the AAD Legislative Conference

Millions of people live with chronic spontaneous urticaria (CSU) — unpredictable hives and angioedema lasting six weeks or longer with no identifiable trigger. In this episode of the Science of Skin podcast, board-certified dermatologists Dr. Ted Lain and Dr. Michelle Tarbox (Chair, Department of Dermatology, Texas Tech University Health Sciences Center, and host of the Dermosphere podcast) break down what CSU actually is, why it's often misdiagnosed as an allergy, and how it's treated — from first-line antihistamines to omalizumab (Xolair) to the newest option: Rhapsido (remibrutinib), the first oral BTK inhibitor approved for CSU. In this episode, you'll learn: How CSU is diagnosed and why it's classified as a skin disease, not a true allergyThe autoimmune vs. autoallergic subtypes driving chronic hives and angioedemaWhy antihistamine updosing often falls short — and its impact on quality of lifeHow BTK inhibitors like remibrutinib (Rhapsido) work differently than biologics like omalizumabReal patient stories on the toll of chronic hives, misdiagnosis, and finding reliefThis episode is sponsored by Novartis with content independently created by the Science of Skin podcast. ⚠️ This content is for educational and informational purposes only and reflects the personal research findings and opinions of the speakers.

Dr. Ted Lain welcomes Dr. Mona Shariari — Associate Clinical Professor of Dermatology at Yale School of Medicine, Associate Director of Clinical Trials at Central Connecticut Dermatology, and host of the Medical Sisterhood Podcast — for a deep dive into one of dermatology's most persistent challenges: polypharmacy and topical confusion. Ted and Mona look back at the old-school regimens dermatologists used to write out — one topical for the face, another for the body, different products for weekdays versus weekends — and how that complexity set patients up for poor adherence and side effects like skin thinning and hypopigmentation from steroid overuse. They discuss why once-daily, non-steroidal options like roflumilast cream and foam have changed the equation, allowing head-to-toe use without the body surface area and duration limits that come with topical steroids.

Dr. Ted Lain and Dr. Patti Farris cut through the hype around today's most popular longevity supplements. They dig into the real (and often surprisingly thin) clinical evidence behind NAD precursors like NMN and nicotinamide riboside, the gut-derived compound Urolithin A, creatine for brain and muscle health, multivitamins and the buzzy Cosmos trial, and off-label rapamycin use. Along the way, they talk through epigenetic clocks, precision medicine, why mouse studies don't always translate to humans, and why "TBD" might be the most honest verdict on longevity science right now. Plus, details on their upcoming Science of Skin Longevity Summit, February 19–21, 2027, in Scottsdale, Arizona.
