Alyuva’s Lip Balms are emollient, humectants and occlusive moisturizer. Occlusive moisturizers fill the cracks in dry skin and make a film that prevents water loss. Emollient moisturizers soften the skin and help to keep it supple. Humectants create a barrier on the skin surface to prevent water loss; instead they bond with water molecules and draw water to the skin. Thus, Alyuva lip balms are both moisturizing and hydrating. This lip balm include Blueberry Essential oils to keep your lips coated with cool fruity fragrance.
