a double dose of treatment, when you use MD Complete by Dr. Brian Zelickson. I am using their Anti-Aging Youthful Skin Sun Shield- broad spectrum spf 50. It hydrates while it protects from uva and uvb rays. It is very lightweight on your skin, but it is made to absorb quickly, even when used with rich moisturizers. It leaves a matte finish and has zero smell.It uses vitamin c to guard against free radical damage, brighten, and tone. Essential Fatty acids strengthen skin’s barrier and hydrate to fight fine lines and wrinkles.So keep your skin looking young , while protecting it with MD Complete. So rub this stuff everywhere,don’t ignore your double d’s….
