Dry skin naturally produces less sebum than other skin types. Therefore, the hydrolipidic film that protects it is more fragile. This means your skin is more sensitive to external stress factors. What is the right routine for dry skin? The HYDRA range. First, an ultra-gentle, moisturizing cleansing routine with HYDRA Cleansing Milk. Second, a nourishing serum with a liquid texture for quick absorption, such as Optimum Moisturizing Serum. Third, a cream-like mist, City Mist, for a shot of hydration at any time of day.
