Tanuj Nakra and Suzan Obagi, two leading experts in aesthetic medicine, join Peter to explore the science of facial aging and skin health as well as the responsibilities physicians face in the world of cosmetic procedures. In this episode, they examine the biological and hormonal drivers of facial aging, the evolutionary and psychological foundations of attractiveness, and the impact of modern media on beauty standards. They discuss the rise in cosmetic procedures among adolescents and the ethical responsibilities of physicians in these cases. The conversation then shifts to a practical, evidence-based guide to skin health—covering the use of mineral sunscreens, retinoids, vitamin C, and tailored skincare routines, as well as the management of acne and the psychology behind aesthetic consultations. The episode culminates in a candid, personal assessment of Peter's own face, offering a revealing look at what aesthetic medicine can achieve and how to think critically about pursuing it.
