I bought this serums thanks to Caroline Hirons! The best serum used, for post acne spots, or any kind of pigmentation! It really works, it's a bit expensive but it's worth the investment! 

I bought this recently to fill the serum-shaped hole in my routine. It feels nice to use and plays well with everything else I use. Haven't been using it long enough to notice a difference yet but my skins definitely seems clearer.
