Sesderma Hidraderm Hyal Liposomal Serum is ideal for the dehydration caused by dermatological or oncological treatment (chemo and radiotherapy). It is suitable for all skin types even for sensitive ones. Hidraderm Hyal is a direct source of hyaluronic acid, in contrast to the precursor (N-acetyl D-glucosamine and D-glucuronic acid), which require the subsequent creation of the molecule. It contains 3 types of hyaluronic acid with multilayer moisturizing properties, from low molecular weight HA that has filling properties to high molecular HA that deeply hydrates the skin.
