What it is: A medical grade anti-aging serum with ceramides that visibly firms skin and reduces the look of wrinkle and dark spots while refining pores.What it does: Retinol supports collagen, protects from free-radical damage caused by pollution and exfoliates dead skin cells from the skin's surface. Lipids keep skin hydrated to firm its appearance and minimize dryness and redness, too. It protects against the external factors that contribute to aging, including pollution, climate and irritants. How to use: After cleansing, apply to your face, neck and the back of your hands. Apply in the evening only for the first two weeks, then twice a day if tolerated. Follow with moisturizer and always use an SPF in the morning. 1 oz. Paraben-free; sulfate-free; phthalate-free Made in the USA
