Kyoku For Men SKN FC 901 Facial Moisturizer with SPF 15. The #1 cause of skin damage and aging is damage from UV rays. Even if your not on the beach, most men are exposed to 2.3 hours, on average, of direct UV exposure through their office window, car, and time spent in the outdoors. This kind of exposure leads to all sorts of skin problems, from frequent breakouts all the way to a leathery skin appearance. Our Facial Moisturizer SPF 15 helps guard the skin from every day problems while also moisturizing and hydrating so you can look totally flawless.
