Skin tint/ BB cream at Mecca

I have a gift voucher to spend at Mecca and really want to get a good skin tint/ bb cream, that can replace my HG foundation. Skin is dull and dehydrated these days and the my Nars full coverage foundation just doesn't look like it used to on my skin. Would still like a little bit of coverage for the dark spots but with a dewy skin like look. Any reccs would be appreciated!
