This is an illuminating serum complex corrector. Not sure how it correct, as it’s quite a sheer glowly product. It’s pretty much translucent with an after glow effect. I guess this is nice cause you can put it together with your moisturiser or foundation for an extra glow. It’s actually quite subtle, like tiny freckle of diamond. Then it will subdue down. So it won’t be so crazy. It’s nice if you want some subtle glow on your skin. I wouldn’t recommend this for oily skin.
