Quench your thirsty skin and replenish it! # The facial skin is extremely thin and sensitive to external elements such as sun and wind. It can quickly become dehydrated. Moisturization is the basis for beautiful skin. Moisturizing with facial care products, serums and/or masks is therefore necessary to nourish the skin, regardless of the skin type; while rich products are better adapted to dry skin and fluid, light products are better adapted to oily skin.
