It's amazing. It's not a treatment, just a cosmetic product, but it does exactly what it promises. It kind of smoothes over/spackles in the pores so they're completely invisible, yet it's the lightest, most translucent thing ever. It quickly takes on a powder-smooth finish, very matte. You can use it on its own, or as a primer under foundation and your skin will look like porcelain.
Yeah, I love the stuff.
