Mayo Clinic Dermatologist: 5 Daily Habits That Are Aging Your Skin Faster & What to Do Instead

Episode of The Mel Robbins Podcast · October 19, 2026 · 1 h 30 min

Mel Robbins and Mayo Clinic dermatologist Dr. Saranya Wyles discuss what skin reveals about overall health and five pillars for healthier skin aging.

Summary

Mel Robbins hosted Dr. Saranya Wyles, a Mayo Clinic dermatologist and physician-scientist, to discuss skin as a "check engine light" for overall health. Wyles argued that skincare is healthcare, citing links between severe psoriasis and cardiovascular risk and studies tying perceived facial age to cancer prognosis and survival. She outlined the skin's functions, including repair, barrier defense, vitamin D synthesis, immune surveillance and thermoregulation. Robbins underwent an AI facial skin scan on camera, which estimated her skin age at 61 against her actual age of 57.

Wyles then presented five "skin span" pillars: sleep, diet and hydration, movement, stress reduction, and topicals and treatments. She described the skin's circadian defense and repair modes, recommended magnesium L-threonate before bed, a low-glycemic, high-fiber diet to reduce glycation, and a smoothie of apples, beets and carrots based on her grandmother's advice. She said drinking water alone does not hydrate skin, recommended tub moisturizers with humectants and fragrance-free labeling, and cited studies showing exercise and resistance training improve wound healing and skin elasticity. She also discussed cortisol and the skin, stress-related hair shedding, pumpkin seed oil for hair loss, and nail changes as health clues.

On topicals, Wyles cautioned against unregulated injectable peptides such as the "Glow Stack" while endorsing topical copper peptides. A UV-camera demonstration showed mineral, chemical and tinted sunscreens blocking UV while coconut oil and beef tallow did not. Using layered cakes, she explained that jowls result largely from bone loss and that GLP-1 weight loss causes facial fat loss, recommending strength training and, later, energy-based treatments such as micro-focused ultrasound. The episode closed with Wyles's message that "the face gets the marketing budget, but the whole organ deserves the care."

Key points

What was said, by whom, with the exact words. Timestamps jump to the moment.

Saranya Wyles
Wyles argues that skin is a two-way conduit reflecting internal health and that changes in it should be treated as health information rather than vanity.
“Your skin is more than a beauty scorecard. It is actually information. It's a two-way conduit between the outside world and the internal systemic health”
Listen from 3:28 · Skin as an indicator of systemic health
Saranya Wyles
Wyles cites a study finding that severe psoriasis carries roughly a six-fold increase in 10-year risk of heart disease and heart events.
“if you have severe psoriasis, you're at about six-fold increased risk to your 10-year heart disease and heart event risk”
Listen from 6:46 · Psoriasis
Saranya Wyles
Wyles reports that just two consecutive nights of three to four hours of sleep disrupt the skin barrier.
“two consecutive nights of three to four hours of sleep disrupts your skin barrier”
Listen from 22:33 · Sleep and skin repair
Saranya Wyles
Wyles explains that skin runs on a circadian clock, defending during the day and repairing at night, making sleep critical for skin health.
“So your skin doesn't sleep at night. It actually shifts into repair mode. And this is why sleep is critical for skin health”
Listen from 23:18 · Sleep and skin repair
Saranya Wyles
Wyles recommends magnesium L-threonate taken one to two hours before bed for sleep and skin matrix support.
“So magnesium threonate is the one that helps with sleep, especially”
Listen from 28:41 · Magnesium supplementation
Saranya Wyles
Wyles cites a 12-week randomized trial in which a low-glycemic diet produced a 23% improvement in acne flares.
“they found that these patients had a 23% improvement in their acne flares just by switching their diet”

Saranya Wyles
Wyles says drinking water alone does not hydrate the skin barrier and that moisturizer must also be applied.
“the myth around hydrating your skin is that people think drinking water is enough to hydrate their skin barrier”
Listen from 40:10 · Diet and skin health
Saranya Wyles
Wyles recommends tub moisturizers over pump lotions because pump formulas contain added water and evaporate faster.
“You also want to look for moisturizers that are tub lotions that you can scoop out versus pump lotions”
Listen from 42:46 · Skin aging
Saranya Wyles
Wyles says resistance training plays a bigger role than cardio in skin elasticity and recommends it for patients on GLP-1 medications.
“It's a combination, but resistance training plays the bigger role”
Listen from 48:11 · Resistance training
Saranya Wyles
Wyles explains that stress-related hair shedding typically appears three to four months after a stressful event and is reversible.
“it'll take about three or four months to be reflected on your skin and your hair”

Wyles warns that injecting unregulated peptides outside clinical trials amounts to self-experimentation.
“Anecdotally, we're hearing benefit, but we can't generalize that and provide guidelines without having clinical trials”
Listen from 59:05 · Peptide therapy
Saranya Wyles
Wyles does not recommend the injectable Glow Stack peptide combination and instead advises topical copper peptides.
“So that stack is something that I don't recommend. Instead, I say use a topical copper peptides”

Saranya Wyles
Wyles demonstrates that coconut oil and beef tallow offer no UV protection and may increase burn risk.
“You actually have a higher risk for burning with coconut oil and beef tallow”
Listen from 1:06:12 · Sunscreen
Saranya Wyles
Wyles advises keeping sunscreen in the car because UV rays penetrate even tinted windows during commutes.
“Even if it's tinted, you should still apply sunscreen in your car”

Saranya Wyles
Wyles explains that jowls are mainly a structural descent problem driven by bone loss rather than a skin problem.
“Because what you are seeing is a descent problem. It's a gravity problem”

Saranya Wyles
Wyles states that every 20 pounds lost on GLP-1 medication corresponds to about 10% facial volume loss.
“For every 20 pounds of weight that you lose on a GLP-1 medications, that's a 10% facial volume loss”
