Sesderma Hidraderm Hyal Facial Cream 50ml it contains three types of hyaluronic acid combined with a technology that allows for multi-layered hydration. Therefore, it is designed for skin that is dry due to external factors such as dry/cold air/cleansers, and internal factors including aging, eczema, and dermatological treatments. This facial moisturizer works on different levels of the skin, as it uses different molecular weights of hyaluronic acid. High molecular weight HA immediately provides hydration and smoothness, while low molecular weight HA visibly reduces wrinkles. Finally, ultra-low molecular weight HA deeply moisturizes and repairs deep wrinkles.
