I bought this because I was doing some reading on active ingredients in good makeup primers, one being Smashbox HD. Then I saw a blurb on a beauty blog about this product from Monistat having nearly identical ingredients, and they were right. I bought a tube and have been using it for about a week. As unlikely as it may sound, it is a fabulous primer for your foundation makeup! The silicone makes it glide on and it dries in just a few minutes to a matte finish. It prevents makeup from melting off when you perspire, makes foundation glide on seamlessly, and is a fraction of the price of good cosmetic makeup primers! Win-Win! AND you can also use it for the purposes stated on the label!. As with all products of this nature, do not get it in your eyes. Common sense dictates that silicone is not intended for use in the eye area.
