Recently my skin has been in a really good shape, and even wearing a tinted moisturiser feels a bit heavy. I'd still like something to give me a bit of a glow & even our the tone around my cheekbones the tiniest bit, so I've been looking at illuminating serums. Has anyone used serums instead of tinted moisturisers? I found good reviews for Lumene instant glow beauty serum but it's not a brand I know. Any other illuminating/brightening serums that would go a bit of the way to being a tinted moisturiser or am I just asking for too much here?
