781: Turkey Neck November: How to Avoid Platysmal Bands, Crepey Skin, and Sagging

Flashback to this popular topic from the last Thanksgiving! On this week’s episode of Beauty Bytes with Dr. Kay: Secrets of a Plastic Surgeon, I am talking all about the Turkey Neck! Thanks to Botox and fillers, our faces can now look younger than ever, but the neck is a different story. The neck is such an under-appreciated part of the body, and you need to look after it as much as you look after your face. Keep listening as I explain why the neck is so important, along with treatments you can receive to prevent it from sagging.

780: Mitochondrial Health, Peptide Protocols, and The Truth About NAD+ with Dr. Elizabeth Yurth

In this power-packed episode, I sit down with longevity expert Dr. Elizabeth Yurth to dismantle popular biohacking trends and get down to the cellular root of aging. We dive deep into why mitochondrial dysfunction is often the culprit behind chronic fatigue—especially post-viral exposure—and Dr. Yurth walks me through her safety-first "replacement strategy" for cycling peptides like Thymosin Alpha-1, BPC-157, and GHK-Cu to restore what we naturally lose with age . We also have a critical conversation about the NAD+ craze, where I learn why filling the "bucket" with infusions might be fueling inflammation if we don't block the leaks first using compounds like Apigenin . Finally, we explore the game-changing role of plasmalogens for insulating our nerves against brain fog and why we are moving away from Metformin to protect our muscle gains . Guest Information: Dr. Elizabeth Yurth is the Medical Director of the Boulder Longevity Institute. You can find her educational resources at bli.academy and on Instagram @DrYurth.

779: Picking Lip Filler To Fit Your Aesthetic

Happy Friday, Beauty Byters!  In this week’s Five Minute Friday, I am joined by my patient Samantha who is the co-founder of Links Financial! We talk about starting small with filler because you want people to take you seriously, to pick lips that fit your branding- but to not get tied to a stereotype. Samantha believes that looking more powerful and attractive can make her feel even more confident in the boardroom, and at the end of the day who doesn't appreciate a pretty business woman. However, I believe is a fine line between sexy and porn star and lately I have been talking people down from getting too much lip filler. Listen in to hear our conversation about lip filler! I love informing my Beauty Byters with new information! Have a question or something you’d like covered on the podcast? Send me a DM or email info@beautybydrkay.com!

778: Peptide Power, The Skin Barrier, and In-Skin Vitamin D Production with Patricia Boland of Colorescience

Join Dr. Kay for a deep dive into cosmetic science with Patricia "Trish" Boland, SVP of R&D at Colorescience. This episode explores the critical importance of the skin barrier, its surprising connection to systemic health (including the gut and brain), and the latest innovations in mineral sunscreens that protect against UV, HEV (blue light), and IR. The main focus is a revolutionary new concept: stimulating the skin's own Vitamin D production. Trish explains how a unique chronopeptide can activate the skin's Vitamin D receptors (VDR) and synthesize Vitamin D in keratinocytes and fibroblasts, all without UV exposure, a groundbreaking approach to achieving barrier health and skin luminosity.
