Retinol is the classic healthy aging skin care product, but do you know why? “Retinol binds to retinoid receptors within skin cells,” board-certified dermatologist Joshua Zeichner, M.D., once told mbg. This “activates genes that upregulate collagen production.”
Studies back this claim, too: In one small human study1, retinol treatment stimulated collagen production in mature skin, thus decreasing the appearance of wrinkling. However, it is important to note that use of retinol can make the skin more susceptible to UV damage—so don’t skimp on your daily SPF.
