Sesderma ESTRYSES Anti-Stretch Mark Serum Forte is an intensive shock therapy of stretch marks formed on a permanent basis, with recovering, regenerating, exfoliating, moisturizing and protective properties. Due to the presence of retinol it is not recommended to use during pregnancy. Problem with stretch marks? Whether transverse stripes appeared on the thighs, abdomen, breasts or buttocks – they are not dangerous to health, but often cause considerable trouble. Serum Forte acts double: combats existing stretch marks and prevents new ones. Active substances enclosed in the liposomes reach the dermis where they can act effectively. Skin becomes tense, firm and its density increases, so it is not susceptible for stretching and deformation.
