Estrogen stimulates the production of collagen and elastin. As estrogen declines during perimenopause and menopause, collagen and elastin production are reduced, leading to a loss of elasticity and an increase in sagging, skin dryness and impaired barrier function as well as fine lines and wrinkles. Mystro Revive Renewing Serum rejuvenates the look of mature dry skin affected by hormonal decline. Formulated with P.A.T.H.[13] and TAP (antioxidant support), this nourishing serum helps address the appearance of skin firmness, elasticity, crepiness and lines and wrinkles while also providing barrier support. - Dermatologist tested - Non-comedogenic - Formulated without parabens & fragrance
