The Green Science collection from AVEDA uses certified organic nopal cactus and argan oil to boost skin’s natural cellular renewal and collagen production. The Lifting Serum ($53) promotes surface turnover, and improves the skin’s moisture and strength; the Line Minimizer ($85 for a package of 10 tubes) reduces the appearances of fine lines and wrinkles; and the lotion-like Replenishing Toner ($39) refines pores and gently exfoliates while moisturizing.
