I actually don't use this BB cream anymore because the coverage is terrible and i do like at least a medium coverage that i can build for me to be happy with how i look. This product has very little coverage at all it is really sheer and you can't really build it.
You can layer this all you want but its sheer like a moisturizer. if you need the coverage this bb cream is a wonderful base so you get all the great benefits and your foundation wont have to be as heavy
I think that the coverage is more sheer like a tinted moisturizer. If you have blemishes or redness they will have to be concealed with concealer. I personally wasn't a fan of the BB cream. I do however love Dr. Jart's BB cream as it matches my skin more and gives me a bit more coverage.
