Fantastic when freshly applied, you really get nice long lashes. BUT, I get black under my eyes, not because it flakes, I wouldn’t say that. But every time I walk past a mirror, there’s a new little black spot under my eyes. It might have to do with it not being waterproof, but I don’t exactly sweat at my office job and it’s not a humid environment either. This has happened repeatedly for several days in a row, so now I’m tired of it and buying another one, never leaving a favorite again!
