I bought this product a while ago, excited to try a vitamin c serum that had L-ascorbic acid in it, in a more stable anhydrous base that would therefore not oxidize so quickly, plus was reasonably priced.
Unfortunately, this didn't work too well for me. I guess if I was to use nothing but this on a clean, dry face, it might be ok but, if you want to apply moisturizer, sunscreen and bb cream/foundation over it, forget it. This serum sits on your face and appears to form a film that doesn't really sink into your skin. When I try to wash it off my hand after applying it, it's very difficult to wash off as it leaves a silicone-type film, much the same as those handcreams that are designed to stay on after several hand washings. When I tried applying other products on my face, even after allowing time for this product to dry or "set" on my skin, they just balled up and rolled off.
