In this episode of Skinside Out, Dr. Zain Husain, Heather, and Courtney continue their Dermatology Through the Decades series by exploring how perimenopause, menopause, hormonal changes, and aging affect the skin—and what you can do to keep your skin healthy and vibrant. The team discusses collagen loss, thinning skin, rosacea, hormonal acne, hair thinning, dryness, pigmentation, enlarged pores, neck aging, and how declining estrogen impacts skin health. They also explain evidence-based skincare routines, hormone replacement therapy, topical estradiol, retinoids, chemical peels, microneedling, lasers, facials, growth factors, and lifestyle changes that can help you age confidently. Whether you're entering perimenopause, already in menopause, or simply noticing your skin changing after 40, this episode offers dermatologist-backed guidance to help you understand—and proactively care for—your skin.
