Facial Lotion SPF 15 non-chemical sunblock is the first glycolic acid resurfacing agent that is combined with a totally non-chemical sunblocking agent. Facial Lotion SPF 15 is formulated using highly micronized titanium dioxide and the identical percentage of glycolic acid as contained in our regular Facial Lotion. Titanium dioxide is what is known as a "physical block", meaning that unlike chemical agents, it deflects the suns UV rays before they can penetrate the skin. Because of titanium dioxides superior ability to give total protection, it has broad spectrum blocking capabilities that include, UVB, UVA, UVC and infrared rays.
