After 16 years of chronic eczema, I finally discovered why lotions aren’t effective moisturizers
Lotions are 95%+ water. No matter how much lotion you apply, it quickly evaporates from your skin because it's pretty much just water. And when this water evaporates, it strips your skin's natural moisture too - just like when sweat evaporates. Without anything to prevent water evaporation, your skin will remain dry.
