480: Your Biggest Skin Questions, Answered: Lasers, Collagen Banking, Chest Wrinkles & More with Dr. Marnie Nussbaum

Dr. Marnie Nussbaum is a board-certified dermatologist, Clinical Instructor of Dermatology at Weill Cornell, and leading expert in non-invasive aesthetic rejuvenation, known for her natural approach to treating and preventing the signs of aging.

In this episode, we’re answering so many of the burning skin questions I feel like we all have. How do you actually bank collagen—and when should you start? Which lasers are worth doing, what does each one actually do, and how do you know which one is right for you? What’s better: microneedling or Clear + Brilliant? And what can you actually do about chest wrinkles?

Dr. Nussbaum breaks down what’s happening beneath our skin as we age, how to address skin laxity and the deeper layers of the face, why daily maintenance can matter more than a big intervention, and what she recommends starting in your 20s. We also get into peptides, PDRN, exosomes—and why she thinks the science isn’t quite there yet—plus the treatments she believes are actually worth your time and money.

And because Marnie is incredibly fun, direct, and refreshingly opinionated, we also get into what she learned from seeing celebrity skin up close, why she prefers certain drugstore products to luxury skincare, and plenty of beauty hot takes along the way.
