What's the Difference Between Moisturization and Hydration?

There's a difference between moisturization and hydration. 

Moisturizing is really all about creating an occlusive barrier to keep existing water in the skin and preventing TEWL — transepidermal water loss. Hydrating is about binding water to something like a humectant and keeping it on our skin.

The best products combine humectants, proteins, and other moisture binding ingredient with an occlusive ingredient, along with emollients which fill in the crevices between corneocytes, or proteins, that are in the process of desquamation, or shedding.

All of our facial serums at Reviv Serums combine some of the best types of these raw ingredients.
