856: Integrative Aesthetics: The Vagus Nerve, Glycated Collagen, and the Gut-Skin Axis with Dr. Mark Tager Aug 11, 2026

Show notes

Are you looking to optimize your skin health from the inside out? In this episode of Beauty Bytes, I am joined by Dr. Mark Tager, a physician, integrative aesthetics educator, and co-founder of the Vagal Nerve Society. Dr. Tager has authored 12 books, including Feed Your Skin Right and Integrative Aesthetics, and brings decades of expertise in personalized nutrition and regenerative medicine. We explore the true meaning of integrative aesthetics, noting that 5 to 10% of your blood flow goes to your skin, making internal nutrition the ultimate foundation for beauty. We dive deep into the gut-skin connection, exploring how the standard American diet glycates your collagen and why maintaining a healthy microbiome with dietary fiber is essential for producing neurotransmitters. Dr. Tager also breaks down the incredible science of the vagus nerve, explaining its role in the body's inflammatory reflex and how tools like 4-7-8 breathing and the Truvaga transcervical device can calm a "wired and tired" nervous system. Finally, we discuss the "wild west" of peptides, the importance of genetic testing for personalized supplementation, and the psychological hardiness required for a long, passionate life.

Lipid Barrier Repair, Dryness, Inflammation - Join us in this week's podcast episode as we discuss the impact of summer heat on the skin, particularly focusing on issues such as dryness, irritation, and barrier disruption. We explain the importance of maintaining the skin's hydro lipid barrier, which acts as a protective layer against environmental aggressors. With summer coming to a close, we offer practical advice on how to care for the skin after these hot months, including the benefits of moisturizing soaks, the use of ceramide-rich products, and the importance of avoiding over-exfoliation. From the role of diet to end-of-summer chemical peels, we provide a comprehensive guide to maintaining a healthy skin barrier to rejuvenate and repair sun-damaged skin as we step into fall!

854: The Secret to Skin Resilience: Wound Healing, Sunburns, and Beta Glucan Aug 04, 2026

Show notes

Are you ready to discover the next massive breakthrough in skincare and immunology? In this episode of Beauty Bytes, I am joined by Dr. Jocelyn Strand, a naturopathic physician and the Vice President of Clinical Education and Research at BWH Labs. Dr. Strand breaks down the incredible, largely untapped science behind beta glucan, a complex polysaccharide molecule that acts as a powerful biological signal for your innate immune system. We dive deep into why the skin should be viewed as an immune organ and how specific 1,3/1,6 beta glucan molecules—isolated from yeast cell walls—perfectly bind to pattern recognition receptors on our immune cells. Dr. Strand explains the fascinating concept of "trained immunity," where beta glucan creates functional epigenetic changes that awaken and coordinate our first responder cells, creating a broader, more efficient readiness against environmental stressors. We also discuss how applying beta glucan topically can accelerate wound healing after cosmetic procedures, instantly soothe severe sunburns, improve overall barrier hydration, and clear out damaged tissue caused by inflammaging.

Dr. Chen also shares actionable holistic advice to help modern audiences calm their chronic fight-or-flight responses. We dive into why you should stop drinking ice water, the specific herbal teas that detox the liver and balance the blood, and how you can manually stimulate your vagus nerve at home without acupuncture needles.

In this episode of Beauty Bytes, I am joined by Rachel Swanson, a registered dietitian, clinical nutrition expert, and the author of Trying. Rachel introduces us to "Fertility 2.0," a proactive, science-backed approach that treats reproductive issues as a canary in the coal mine for our overall systemic health and future disease risk. We discuss why Polycystic Ovary Syndrome (PCOS) is now being recognized as Polyendocrine Metabolic Ovary Syndrome (PMOS), with up to 95% of these patients suffering from insulin resistance. Rachel breaks down the exact metabolic biomarkers you need to track—including fasting insulin, HbA1c, and waist circumference—and explains why the "normal" lab range is not always optimal. We also explore the fascinating connection between fertility and three different microbiomes (oral, vaginal, and gut), how to use Continuous Glucose Monitors (CGMs) to flatten your spikes, and the everyday endocrine disruptors you need to throw away right now.

Are you ready for the ultimate list of beauty, health, and relationship secrets we completely refuse to keep to ourselves? In this Five Minute Friday episode of Beauty Bytes, I am joined by the fabulous Margo Graff to share 10 game-changing tips that every girl needs to know.

We dive into everything from clearing up cystic acne by ditching toxic laundry detergents and dryer sheets, to using glycolic acid wipes on your armpits to kill odor-causing bacteria. We also break down the importance of "protein maxing" with 1 to 1.5 grams of protein per pound of body weight, and why ditching messy topical serums for oral minoxidil is the ultimate hair growth hack. On the cosmetic side, we debate the rising trend of the "38-year-old facelift," why you really only have two good facelifts in your lifetime, and how combining a chin implant with early fat transfer can naturally stretch and lift the face.

Beyond beauty, Margo shares her incredible advice for stepping into your feminine energy: stop giving away "Costco samples" of your value or handing out "participation trophies" to people who put in zero effort. Plus, we cover the anti-aging magic of hard-shell hyperbaric oxygen chambers for rebuilding your DNA's telomeres, and how mastering sales psychology can completely transform your personal and professional life.

Are you experiencing subtle changes in sleep, mood, or resilience and wondering if it could be perimenopause? In this episode of Beauty Bytes, I am joined by Dr. Jessica Shepherd, a board-certified gynecologist, Chief Medical Officer for Hers, and the author of the new book Generation M. We are completely reframing the conversation around menopause, transforming it from a time of fear into the "magic of midlife".

We tackle the widespread confusion surrounding Hormone Replacement Therapy (HRT), debunking the 20-year-old WHI study and addressing the misplaced public fears linking estrogen to breast cancer. We also discuss her work at Hers, the benefits of microdosing GLP-1s for weight maintenance and longevity, and the absolute necessity of safe peptide sourcing. Finally, Dr. Shepherd shares the exact advanced labs and supplements—including her personal creatine and hormone stack—that every woman should utilize to optimize her aging trajectory.

847: Why I’m Adding a Vibration Plate to My Longevity Routine Jul 10, 2026

Show notes

Are you wondering if standing on a shaking platform actually counts as exercise, or if it's just another wellness gimmick? In this Five Minute Friday, I am breaking down the incredible science behind whole-body vibration plates and why I just added a $59 Amazon vibration plate to my daily longevity routine.

I dive into the compelling data showing how these rapid mechanical movements force your muscles to continuously contract, significantly improving lower body power, walking endurance, and sit-to-stand performance. We also explore how vibration therapy improves proprioception, increases lumbar spine bone mineral density for postmenopausal women at just 30 hertz, and even helps reduce Hemoglobin A1C in people with type 2 diabetes by pulling glucose out of the blood. Finally, I share my personal tips on how to use it safely—from doing morning squats to applying my skincare regimen right on the plate!
