SkinMedica TNS Recovery Complex: Tthe most advanced formulation available, takes your complexion beyond AHAs, Retinols, and Topical Vitamin C, for improving the health and appearance of sun damaged and aging skin without burning, peeling or irritation. This product is amazing. I have been using it since we started carrying this line and was astounded. I could feel the skin feeling tighter within a week. Our esthetician had the same result. It works beautifully with all other skincare products was well the Retinol and Vitamin C Complex. Twice daily application improves the appearance of the skin, makes fine lines appear less visible and gives the skin a healthier look. 0.5 fl oz
