Obagi 360 Retinol 1.0 is a fast absorbing, potent serum that reduces the appearance of fine lines and wrinkles with its highly concentrated formula. A derivative of vitamin A, retinol promotes cell turnover which reduces the formation of fine lines and other premature aging signs on the skin. It also aids in the production of collagen, a protein that supports the skin’s elasticity for a youthful appearance. The entrapped retinol delivery system, in The Obagi 360 Retinol 1.0, allows the retinol to be time-released diminishing the chance of irritation while working to smooth the skin’s texture for an even complexion.
