^ Skin79 has pretty good coverage I think, but then its a bit thicker than the other more sheer BB creams. Since you said you have a bit of blemish I suggest something like SkinFood BB creams in ginkgo or aloe vera. Since the price isn't too bad, you could try it out and if you don't like it, it's not too much of a loss

SkinFood BB cream is really sheer and quite moisturizing (for your dehydrated skin) I recommend trying it!
