Obagi360 Retinol 0. 5 is an ideal product to introduce your skin to retinol treatments. A lower concentration of 0. 5% retinol boosts cell turnover to minimize acne, fine lines and wrinkles while diminishing hyperpigmentation. Hydrating jojoba oil and shea butter promote firmness and elasticity as vitamins C and E work synergistically to neutralize free radicals. *Packaging May Vary.
