ESTRYSES is a cream with a unique formula that reduces the depth, length, and roughness of the stretch marks. Estryses contains a complex of reducing ingredients for stretch marks by moisturizing, revitalizing the skin, increasing its strength and elasticity, reducing flaccidity, and stimulating collagen synthesis. It works by fighting the stiffness of the fibers, as it improves skin elasticity and reduces flaccidity acting directly on the stretch marks.
