Having finally gotten serious about my SPF, I upgraded with two sunscreens from the anti-aging store. The first base SPF is by ZO, then I add a primer (GLO), and then a final double pump of the Skinmedica Daily Physical Defense tinted sunscreen. It may be overkill on the sunscreen, but the double-up approach was recommended to me by someone with glowing skin, AND, as I spend a lot of time outside, I feel this offers me the best protection.
Love this SPF. Absorbs nicely under BB cream. Great protection.
