Plastics & Peptides Episode 3 Description

Park Avenue plastic surgeon Dr. Darren Smith and Park Avenue internist + longevity expert Dr. Amanda Kahn sit down with beauty industry veteran Jessica Matlin to discuss some of the need-to-know beauty + wellness topics of today.

What you’ll hear in this episode:

What People Want: Jessica fills us in on shifting consumer behaviors, what people are looking for and how retailers are delivering.

The Democratization of Beauty: How social media flipped the dynamic between expert and consumer. And how beauty authorities are now able to speak directly to their audiences, which has created a savvier, more informed consumer.

Doctors on Social Media: Dr. Smith weighs in on how surgeons present themselves online, and how those choices often mirror their surgical strategy and results. The group makes the distinction between using social media to teach and share knowledge versus using it for marketing and branding.

Beauty Routines for the Busy Mom: Jessica shares her non-negotiable beauty steps as a mom and industry leader. She walks us through her skincare and makeup routines and lets us in on a few of her favorite products.

Plastic Surgery Trends: Dr. Smith highlights the procedures patients are requesting most and the growing preference for subtle, “optimized” results over dramatic transformations.

Longevity, Energy, and Anti-Aging: Dr. Kahn explains how she uses peptides and NAD+ to help patients improve energy and optimize the aging process. She identifies daily habits that quietly drain energy, noting the importance of community and the correlation between happiness and longevity.

Supplements at the Intersection of Beauty and Wellness: Jessica discusses the convergence of beauty and wellness, and the role that supplements are taking in that process. The group covers which supplements offer real benefits versus ones that overpromise.

AI and Self-Diagnoses: Dr. Smith and Dr. Kahn explore how patients are using tools like ChatGPT to research symptoms and attempt to self-diagnose, and why guidance from board-certified physicians still matters.
