Glycerin for Eczema (Atopic Dermatitis)

A workhorse hydrator that pulls water into your skin. In nearly every good moisturizer for a reason.

Why it works for Eczema (Atopic Dermatitis)

Pulls water into your skin and keeps it hydrated. Glycerin is a humectant your skin already works well with, drawing moisture from the air into the outer layers. It is a main ingredient in many National Eczema Association-approved moisturizers (CeraVe, Cetaphil, Vanicream). In a controlled study (Pan 1997, PMID:9231648), glycerin clearly improved skin hydration and barrier function.

How Glycerin works
