• Joint Effort: CBD and Your Skin

  CBD is everywhere, but what does it actually do for your skin? We sit down with Adam Friedman, MD—dermatologist, chair, and translational researcher—to break down the real science. We clear up CBD vs THC confusion, map how the endocannabinoid system works in keratinocytes, sebocytes, immune cells, and nerves, and explain how CBD influences redness, itch, oil production, and inflammation. We also walk through the legal landscape, why cosmetics are the most realistic path forward, and how to spot mislabeling or contamination when choosing products.Then we get into the data. You’ll hear about research showing CBD can reduce sebum and calm the inflammasome in acne, early evidence for atopic dermatitis and scalp psoriasis, and a controlled human study where topical CBD reduced UVA-induced DNA damage linked to photoaging. We talk through delivery systems like nanotechnology, safety myths, when to avoid CBD, and what a good certificate of analysis should include. If you care about acne control, skin longevity, or smarter routines, this episode gives you a grounded, hype-free guide to CBD in dermatology.

• The Diversity Gap in Psoriasis Care

  Psoriasis doesn’t look the same on every skin tone. In this episode, we break down how psoriasis appears on darker skin, lighter skin and mixed tones, why inflammation may look purple, brown or gray instead of red, and why these differences can delay diagnosis. We explore the limits of the Fitzpatrick scale, how ancestry shapes skin response, and what patients with melanin-rich skin should know about treatment, light therapy and pigment changes.With dermatologist Dr. Mona Shariari, we explain how to recognize psoriasis on different skin tones, what symptoms to watch for, and how to advocate for accurate care. If you’ve ever wondered what psoriasis really looks like on brown or Black skin—or why your symptoms don’t match online photos—this episode brings clarity, science and practical guidance.This episode is sponsored by Eli Lilly.
