Can you explain the different types of moisturizers for atopic dermatitis?

Atopic Dermatitis

You. The moisturizers are very complicated, even though we think it's a very simple issue. But there are two major types. We have occlusive moisturizers, just like vaseline, that occludes the skin. But if you occlude the dry skin, what good is it going to do? Absolutely nothing. Then we have humectants. Humectants, they actually attract humidity and water from the deeper layer of the skin as well as from the atmosphere. So then the humectants bring humidity and water to the skin. However, because of trans epidermal water loss and impaired epidermal barrier, especially in atopic dermatitis patients, the water is going to come as fast as it's going to live as fast as it comes, and it will evaporate. So we do need occlusive moisturizers. So the combination of those two is the ideal moisturizer.
