Key Ingredients: Hyaluronic Acid: Hyaluronic acid aids in smoothing and plumping the skin, while providing an extra burst of moisture.. Ethylhexylglycerin: This ingredient acts as gentle preservative.. Formulated Without: Sulfates: DIME products never contain skin-irritating ingredients such as sulfates. Sulfate-free products are gentle on the skin and can help decrease the chances of an allergic reaction..

Since some phthalates have been linked to hormone disruption, DIME avoids them..
