The Advanced Retinol day treatment SPF 30 by StriVectin reduces the look of deep set wrinkles and fine lines and hydrates and deeply nourishes skin. It plumps skin to restore its bounce and youthful contour, evens tone and leaves complexion radiant and refines and smoothes skin texture. For the first time, two of the most powerful anti aging actives, NIA 114â"¢ and Retinol, unite in one powerhouse treatment. For Retinol (vitamin A) to achieve age fighting potency, it needs Niacin (vitamin B) to convert to its active form. StriVectin's proprietary NIA 114 molecule is one of the most active forms of Niacin. It has the ability to absorb deeply into skin and strengthen the moisture barrier, reducing Retinol sensitivity. Working as a dynamic duo, NIA 114 activates Retinol's age fighting power to work harder, faster, smarter without the irritating side effects. So you get superior age fighting benefits throughout the day to fight deep set wrinkles, even out tone and texture, and deeply nourish skin.StriVectin Advanced Retinol day treatment SPF 3050ml
