The MD Formulations Hydrate line provides essential moisture to the skin and is for daily use with other products from MD Formulations. Moisturizers from MD Formulations help retain water within the layers of the skin to prevent dehydration. MD Formulations Hydrate plumps the skin to soften the look of lines and wrinkles. MD Formulations Hydrate products can be used after cleansing and once treatment products have absorbed into the skin.
