I love this stuff. I use it to cover up my blemishes. I apply a little to my concealer brush and apply lightly to my zit. It takes the red out and hides it perfectly. I then use my foundation brush to gently sweep over the area to even out color. Last, I apply a thin layer of powder to set it (with a powder brush) I found that this works because the gold is deflecting the light and doesn't make the zit look red. I love this and think it is worth all the money that I spent on it.
Huge bottle of it, I don't think that I'll ever use the whole thing, but if I had to replace it, I would.
