I bought this thinking it would be the perfect partner in crime to the Revlon Colourstay foundation. Bottom line; it's not.
The concealer itself is quite thick and creamy and a bit difficult to blend. As coverage goes, this is quite sheer. To build up enough coverage to conceal blemishes or undereye circles you need a lot of product. And since this is so thick it means a very cakey look. This concealer doesn't crease at all when you use a thin layer but if you want any sort of coverage you're going to need a thick, cakey layer.
I wouldn't use this again. In fact I think I'd rather use the colourstay foundation as a concealer over this.
I don't personally know why any company would design a concealer that doesn't conceal but it kind of seems like thats what Revlon went for here. I went through a full tube in a month, which for me is ridiculous, from trying constntly to build u coverage. All this gave me is cakey creasy undereyes. However if you want a concealer to cover light discoloration or redness I think this would be a great bet.
