Why Your Skin Isn’t Healing: The Gut, Hormone & Inflammation Connection

AI Summary
5 min readThe Skin Is a Window to the Body
Dr. Mark Hyman opens his conversation with dermatologist Dr. Ramina by describing what he observed early in his functional medicine practice: when he treated patients' underlying health issues—improving nutrition, optimizing gut flora, addressing food sensitivities—their chronic skin conditions often resolved on their own. Eczema, psoriasis, acne, and rosacea that conventional dermatology manages with topical steroids, antibiotics, and immune-suppressing biologics would simply clear up. This observation, repeated over decades, led him to a conviction that the skin is not an isolated organ but a reflection of what is happening inside the body.
Dr. Ramina arrived at the same conclusion from a different path. Raised by a Japanese mother who used alternative approaches to healing, she entered medical school with an open mind but got "sucked into the vacuum" of conventional training. After residency and private practice, she found herself prescribing the same suppressive treatments she had learned—steroids, biologics, retinoids—and watching patients improve only as long as they stayed on the drugs. "It's not really getting to the root cause," she says. "I'm so grateful for these treatments because it makes people more comfortable, but it's not really healing the underlying issue."

Show Notes
Early in my career, I noticed that patients’ skin often improved as we addressed their nutrition and gut health. That changed how I approached skin concerns and taught me to look beneath the surface for contributing factors.
Today, I’m joined by triple board-certified dermatologist Dr. Mamina Turegano, co-author of The Holistic Psoriasis Management and Nutrition Guide and an advocate for Timeline’s approach to skin health. Together, we explore what your skin can reveal about your overall health and how that understanding can help you make more informed choices about caring for it.
You’ll learn:
How damaged mitochondria contribute to skin aging, and how urolithin A may support healthier skin through mitochondrial renewal
How your gut health, hormones, and insulin resistance may be contributing to recurring acne and other skin concerns
How menopause changes your skin, and what to consider if it becomes drier, thinner, or less resilient
How strength training may benefit your skin alongside your muscles
Which skincare basics to prioritize before investing in newer treatments and supplements
Like most people, I care about how my skin looks, but I also want to understand what helps it stay healthy and resilient. That’s how I approach aging more broadly: learning what my body needs and making those choices part of everyday life.
