826: The Menopause-Gut Connection: Stopping LPS Toxins, Fixing Leaky Gut, and Hacking Aging Apr 29, 2026

Show notes

Are your expensive 10-step skincare routines actually destroying your skin’s first line of defense? In this mind-blowing episode of Beauty Bytes, I welcome back Kiran Krishnan, a brilliant research microbiologist and health educator, to completely redefine how we think about the gut-skin axis.

We start by breaking down the "acid mantle"—why your skin must stay at a highly specific pH (4.5 to 5.2) to prevent fungal overgrowth, acne, and severe dryness, and why you are likely over-cleansing. We also dive into the systemic changes that occur during midlife, exploring how declining estrogen levels create a "leaky gut" that allows LPS toxins to flood your system, accelerating aging and inflammation. Kiran shares the exact protocols to reverse this, from using spore-based probiotics and lactoferrin to hacking the "centenarian microbiome" with fiber and polyphenols. We even discuss "psychobiotics" that act as nature's stress relievers, and the exact topical protocol you should use after microneedling and lasers.

825: The Trouble with Tanning Beds Apr 25, 2026

Show notes

Hi beauties!

On this week's Five Minute Friday, I talk to you about tanning beds and the risk that comes with them! As a facial plastic surgeon, I know a thing or two about the negative effects tanning can have on your skin. More than a million cases of skin cancer will be diagnosed this year and 90 % of those cases can be brought on by sun exposure and tanning beds. With prom season rapidly approaching and many brides getting ready to tie the knot, a "base tan" is more often than not on their checklist. I cover some of the different types of skin cancer, why tanning beds are your skin's worst enemy, and some of the ways you can shield yourself from the sun!

824: The Menopause Gut: Endogenous GLP-1, Akkermansia, and Hacking Midlife Insulin Resistance Apr 21, 2026

Show notes

Why do so many women suddenly experience mysterious bloating, weight-loss resistance, and severe brain fog the moment they hit midlife? In this timely episode of Beauty Bytes, I am joined by Cynthia Thurlow, a nurse practitioner, host of the Everyday Wellness podcast, and author of the highly anticipated new book, The Menopause Gut . We dive deep into a conversation that the medical community has ignored for far too long: the critical connection between declining estrogen and your microbiome . Cynthia explains the concept of the "estrobolome" and reveals how the loss of estrogen literally breaks down the mortar of your intestinal walls, causing leaky gut, new food sensitivities, and systemic inflammation . We explore why treating midlife mood changes might actually start in the digestive tract, considering 70 to 80% of our neurotransmitters are produced in the gut. Cynthia also breaks down the harsh reality of midlife insulin resistance and sarcopenia, while giving us the exact blueprint for reversing it—from tracking macros to hit 100 grams of protein, to slowly building up to 25-30 grams of fiber to stimulate your body's natural GLP-1 production . We even tackle the taboo topic of why you must be pooping every single day to eliminate excess estrogen . If you are tired of being told that midlife weight gain and exhaustion are "just normal," this episode is your ultimate guide to taking your power back.

In this fascinating episode of Beauty Bytes, I am joined by clinical nutritionist Oscar Coetzee to discuss the massive paradigm shift happening in longevity medicine: cultivating powerful "Keystone" bacteria.

Oscar explains why standard probiotics are like buying a bouquet of "cut flowers" that inevitably wilt, and introduces the revolutionary science behind anaerobic strains that actually plant themselves into your gut lining.
