I normally do not wear foundation, tinted moisturizer, or BB cream because I don't really need it.
When I first sampled this product in my birchbox, I was amazed how flawless it made my skin look. This really blew my mind, since it wasn't matched specifically to my skintone. I purchased a full size and use it on special occasions when I want my skin to look absolutely perfect, but not in an overly made-up way. I also appreciate that it does not deposit on other people's clothes when I hug them.
My only complaint is that it does make me break out if I wear it for a few days in a row.
