This is a GREAT primer to put under your foundation, I found this at Sephora! (my fav. makeup store :) ..and it's also good for your skin! I usually sweat while i'm at work, but I like to wear a thin layer of foundation, and i found this primer seems to hold my foundation really well even if I do sweat and also works as a moisturizer! ...I won't lie, it was a little spendy...it was $28 for a 1.01 oz. BUT if your looking just to try it out, it is only $9 for a 0.34 oz bottle! I have the 1.01 oz. bottle, and I use it probably 3 times a week and have had the bottle since July 2009! (...a tiny bit goes a long way!) It is 99% natural and a silicone free and antioxidant rich face primer.
