Sesderma HIDRADERM HYAL Liposomal Serum is ideal for the dehydration caused by the dermatological treatment (corticoids, retinoids etc.) and / or oncological treatment (chemotherapy 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 moisturising properties.
