I'm finishing my second bottle of this, which I've had for about 9 months, as I only use it about 4-5 times a week, only in the evening. After going through my pregnancy in a hot, sticky, humid climate without a single zit or breakout, what else can I do but give it all thumbs up?!? There's a version of this with SPF 15, but somehow I don't believe in AHA and SPF in the same product.
