Ep. 590 “Mastering the "Master Clock!” – Why Late-Night Eating Disrupts Your Cellular Circadian Receptors | Menopause & Sleep

Today, I have the honor of interviewing Dr. Doris Day, a board-certified dermatologist who specializes in cosmetic and longevity dermatology. She is also a clinical professor of dermatology at NYU, recognized for her dedication and excellence in teaching, and is widely regarded as a leader in the aesthetic dermatology field. In addition to her clinical work, Dr. Day is a medical journalist and a prominent media figure. In our discussion, we examine the basics of perimenopause and menopause from a pathophysiology perspective, including the 30% decline in collagen synthesis that occurs during the first five years of menopause. We explore the skin microbiome, inflammation, and inflammaging, and why hydration, electrolytes, reducing processed sugars, and eating a nutrient-dense diet can have such a visible impact on skin health. Dr. Day also explains her approach to facial balancing and how our bones, fascia, muscles, and fat pads age. We discuss topical agents, advanced interventions including lasers, microneedling, PRF, PRP, stem cells, and growth factors, and even touch on emerging research suggesting that certain laser treatments may help reduce the risk of skin cancer. Throughout the conversation, I also openly shared what I have done to support my skin. Stay tuned for today’s fascinating conversation about menopause, skin health, collagen loss, and the evolving science behind modern aesthetic dermatology. IN THIS EPISODE, YOU WILL LEARN: The sudden skin changes many women experience during early perimenopause Dr. Day explains how she personalizes skincare routines for each patient How collagen synthesis rapidly declines during the menopause transition How hydration, sleep, and nutrition can visibly improve skin tone and puffiness How inflammation, blood sugar issues, and poor metabolic health contribute to inflammaging and visible skin aging Why facial balance is more important than trying to erase every wrinkle or line Dr. Day shares how she combines lasers, topicals, and recovery protocols to support skin healing and collagen production How fillers and other cosmetic procedures can create an unnatural appearance when used incorrectly Bio: Dr. Doris Day, MD, is a board-certified dermatologist specializing in cosmetic and longevity dermatology.
