Pediatric Dermatology Guide: Eczema, Psoriasis, Alopecia, Acne & Hemangiomas

Up to 70% of people say they have sensitive skin — but is it really a diagnosis, or something else entirely? Dr. Patti Farris and Dr. Ted Lain break down the biology dermatologists are still trying to figure out.

In this episode of the Science of Skin Podcast, Patti and Ted dig into a 15,000+ person global study on sensitive skin prevalence, and explore the science behind why skin reacts with no visible cause — covering TRPV1 and TRPA1 receptor activity, neuropeptide release (substance P, CGRP), and the connection to rosacea. They also unpack the exposome: how pollution, UV exposure, hormones, menopause, and the skin microbiome all play a role, including a deep dive into aryl hydrocarbon receptor (AHR) activation and inflammation. The episode closes with a new comparative cleanser study using D-Squame tape stripping and colorimetric index of mildness (SIM) testing, showing how Cetaphil Gentle Skin Cleanser performs against other "gentle" cleansers on the market.

Sensitive Skin Syndrome: What's Really Happening to Your Skin

🎧 In this episode of the Science of Skin Podcast, host Dr. Patty Farris sits down with Dr. Rishi Chopra — a Harvard-trained, fellowship-trained cosmetic dermatologist from the Mass General Wellman Center for Photomedicine — for a deep dive into the evolution of fractionated laser resurfacing.

Dr. Chopra breaks down how fractional photothermolysis, first described by Drs. Rox Anderson and Dieter Manstein in 2004, transformed dermatology by moving away from painful, high-downtime ablative resurfacing toward safer, more effective treatments. He walks through the progression from the original Fraxel Restore to the Fraxel Dual and the newly launched Fraxel FTX, explaining the science behind each wavelength (1550nm, 1927nm) and how these advances made treatments more tolerable, more precise, and safer for patients with skin of color.

The conversation also covers a remarkable patient case: a young man with severe acne scarring who saw nearly 100% improvement after six Fraxel FTX treatments — illustrating just how far this technology has come. Dr. Chopra then discusses the Clear + Brilliant Touch, a lower-downtime "lunchtime facial" option that's especially popular with younger patients and serves as both an entry point and a maintenance tool for building long-term patient trust.

Whether you're a dermatology professional refining your device menu or simply curious about the science behind modern laser resurfacing, this episode offers a comprehensive, practical look at how far fractionated laser technology has come — and where it's headed next.

In this episode:
The history of ablative vs. fractionated laser resurfacing
Fraxel Restore → Dual → FTX: what changed and why
Treating acne scars and photoaging safely in skin of color
A dramatic real-world patient case study
Clear + Brilliant Touch as a "lunchtime facial" option
Building patient trust through a tiered treatment approach

This episode is sponsored by Solta Medical. Dr. Chopra has been compensated by Solta Medical for his participation.

Full prescribing and safety information for Fraxel and Clear + Brilliant laser systems is available at www.fraxel.com/HCP and www.clearandbrilliant.com/HCP.
