The Slide Show Ep 1: Skin Barrier Workshop

The Slide Show is a series of mini workshops designed for learning on the go, with easily digestible bullet point slides and helpful visual aides. You'll get my pdf notes sent to your inbox plus an accompanying lecture. In this week's installment, we'll be covering the essentials of skin barrier function—must know skin science for skin experts.

Imagine the skin like a brick wall that serves to protect your skin from the external environment. It keeps out allergens like dust, pollutants and bad germs. At the same time, it also adapts to the environment. Healthy skin adjusts to changes in temperature, humidity and is also adversely affected by disturbances in the microbiome. What you need to understand is that it is ultimately the balance in this ecological system that matters—not precise values. This is why topical antibiotic treatments for various dermatological conditions have failed—acne skin is affected by Cutibacterium acnes, but it isn’t the bacteria alone that’s causing the disease. In this tutorial, I'll take you through the anatomy and physiology of the skin barrier—the foundations of essential dermatology for skin experts.
