870: Fibroblasts, Peptides, and Biological Clocks: Dr. Kay on the LearnSkin Podcast

Are you ready to explore the ultimate convergence of molecular biology and aesthetic medicine? In this special episode of Beauty Bytes, we are sharing Dr. Kay's recent guest appearance on the LearnSkin podcast with Dr. Raja Sivamani! Dr. Kay dives deep into her personal and professional journey into the longevity space, breaking down the molecular mechanisms of aging and why she views facial aesthetics through an integrative, whole-body lens.Dr. Kay explains how accumulated mutational damage, declining NAD levels, and mitochondrial aging exhaust our cellular repair capacities, leading to the senescence we visibly recognize as fine lines and brown spots. She shares her exact protocol for stimulating collagen, detailing why she recommends daily supplementation of at least 12.5 grams of hydrolyzed collagen peptides combined with Vitamin C and a high-protein diet. They also discuss the exciting future of personalized aesthetics—from 3D facial scanning and AI hair metrics to the groundbreaking potential of DNA methylation tape strips that track the reverse-aging of skin cells. If you want to understand how to age like fine wine and support your cellular machinery from the inside out, you will not want to miss this conversation!

Wrinkles, fine lines, and gentle anti-aging-This Five Minute Friday, we're discussing one of my favorite products, Retinol! We know the magical abilities Retinol has by minimizing and improving texture lines, but sometimes Retinol can be a little harsh on the skin. I'm here to bring you up to speed on some less irritating alternatives. Stay tuned to learn more!

Are you unintentionally retoxing your body while you sleep? In this episode of Beauty Bytes, I am joined by Helen Christoni, the Chief Business Officer of AirDoctor and AquaTru, to expose the hidden toxic burdens lurking in our everyday environments.We take approximately 20,000 breaths a day, yet indoor air is often deeply contaminated by off-gassing gas stoves, beauty products, and trapped outdoor wildfire smoke containing dangerous VOCs and ammonia. Helen breaks down exactly what to look for in a medical-grade air purifier, explaining why you need a sealed system with a heavy carbon filter that captures particles as small as 0.003 microns—far smaller than a standard HEPA filter. We also dive into the terrifying reality of our municipal water supplies and microplastics. If you are boiling tap water to make pasta or coffee, you are actually concentrating contaminants like arsenic up to three times their original amount!From the necessity of under-sink reverse osmosis systems and shower filters that remove skin-stripping chloramines, to simple swaps like using soy candles and wiping down surfaces instead of vacuuming, Helen teaches us how to apply the 80/20 rule to our environments. By transforming your home into a clean sanctuary, you give your body the foundation it needs to step out into the world from a position of strength.Special Offers:Upgrade your home's air and water quality using our exclusive listener links: AirDoctor: https://airdoctor.com/beautybydrkay AquaTru: https://aquatru.com/beautybydrkay Guest Information: Helen Christoni is the Chief Business Officer of AirDoctor and AquaTru.

On Today's Five Minute Friday, listen to why it's key to think of how well you support your immune as part of your beauty plan! A weak immune system works against your treatments- causing more swelling, slower recovery, and less collagen response. A strong immune system works with your treatments meaning it will amplify results, shorten downtime, and keep your skin vibrant and youthful. Your immune system is your best beauty ally so let’s make sure it’s ready to help you glow this season and beyond. 

Hair loss is more than cosmetic—it can dramatically affect confidence, identity, and how we perceive aging. In this episode of Beauty Bytes with Dr. Kay: Secrets of a Plastic Surgeon, I am joined by Dr. Richard Chaffoo, a nationally recognized triple board-certified plastic surgeon with more than 30 years of clinical experience and a special focus on hair restoration and regenerative medicine.We break down what is actually happening inside the hair follicle as hair begins to thin and why early intervention matters before chronic inflammation, miniaturization, and fibrosis permanently compromise the follicle. Dr. Chaffoo walks us through today’s treatment spectrum, from oral minoxidil and finasteride to dutasteride, PRP, microneedling, red-light therapy, and his approach to combined regenerative therapy. We also discuss why hair restoration should go beyond simply prescribing a pill or performing a transplant—and why evaluating scalp health, nutritional deficiencies, hormones, and the biological environment surrounding the follicle is so important.Then we dive into the future of hair science. Dr. Chaffoo shares his experience working with researchers at Stemson Therapeutics to create human hair follicles from pluripotent stem cells and successfully grow human hair in preclinical models. We discuss the possibility of hair cloning, follicle banking, regenerating the entire multicellular hair-follicle niche, and a future where patients may be able to preserve their own follicles or generate new ones rather than relying solely on a limited donor supply.Could hair transplantation eventually become obsolete? From stem-cell-derived follicles to regenerative treatments designed to rescue thinning hair before it is permanently lost, this conversation explores how rapidly the science of hair restoration is evolving—and what may be possible in the decade ahead.Guest Information:Dr. Richard Chaffoo is a triple board-certified plastic surgeon and hair restoration specialist based in Southern California. He co-leads La Jolla Plastic Surgery & Dermatology and has been actively involved in research exploring regenerative approaches to hair restoration and human hair follicle development.

Summer heat takes a toll on your skin. In this week’s podcast, we’re talking dryness, irritation, and the breakdown of your lipid barrier. This natural barrier is your shield against environmental stressors, and when it’s disrupted, inflammation follows. As the season shifts, it’s the perfect time to repair and restore. We’ll cover why ceramide-rich moisturizers matter, how hydrating soaks help replenish, and why it’s smart to ease up on exfoliation. Plus, we share tips on diet, recovery treatments, and why end-of-summer peels set you up for glowing, resilient skin heading into fall.

Are you feeling constantly "wired and tired" or struggling to recover from chronic stress and inflammation? In this episode of Beauty Bytes, I am joined by Dr. Scott Sherr, a board-certified internal medicine physician and a leading specialist in hyperbaric medical oxygen therapy (HBOT). Dr. Sherr is the Chief Medical Officer of Transcriptions and a pioneer in Health Optimization Medicine, a foundational framework that utilizes metabolomics to assess and heal your cellular machinery rather than simply band-aiding disease.  We dive deep into the science of hyperbaric therapy, breaking down why varying atmospheric pressures are required depending on whether you are targeting the central nervous system or systemic wounds. Dr. Sherr explains that flooding the body with oxygen creates reactive oxygen species, meaning your mitochondria must be fully optimized with the right antioxidants to actually leverage the benefits of HBOT. We also challenge everything you thought you knew about depression and anxiety, exploring why a deficiency in GABA—your brain's primary inhibitory neurotransmitter—is far more likely to cause your 120,000 racing thoughts a day than a lack of serotonin.  Finally, we discuss the incredible benefits of low-dose methylene blue for instantly boosting mitochondrial capacity, and why this compound is particularly transformative for women navigating the steep estrogen and progesterone drops of perimenopause. Guest Information:Dr. Scott Sherr is the Chief Medical Officer of Transcriptions and One Base Health.

Are you fascinated by the molecular science of aging and senescence? In this episode of Beauty Bytes, I am joined by Dr. Frederick Beddingfield III, the CEO of Rubedo Life Sciences, a physician-scientist, and a former senior leader at Allergan. We focus on the cutting edge of longevity and how Rubedo is developing adaptive senotherapeutics to reverse cellular aging and extend healthspan.  Dr. Beddingfield explains the science behind their lead drug, RLS 1496, which targets the enzyme glutathione peroxidase 4 (GPX4) to regulate ferroptosis, an iron-dependent cell death pathway. We discuss how this drug not only eliminates toxic senescent cells but also acts as a "redox reset" for aged cells, reducing their biological age by improving mitochondrial function and autophagy. We also explore their groundbreaking human clinical trials, which demonstrated a 50% reduction in precancerous actinic keratoses in just four weeks without causing skin irritation. Plus, Dr. Beddingfield shares his personal biohacking stack, including low-dose rapamycin, fisetin, and quercetin.  Guest Information:Dr. Frederick Beddingfield III is the CEO of Rubedo Life Sciences.
