Black Up is a french makeup brand for light and dark black skins. Available on Sephora online shop, you can also buy it in Black up stores (France). The best seller of the brand is the contouring stick inspired by the makeup technic of the same name. Five tones are available. I have tested the n°5, the deeper shade. The product is AMAZING ! I really love it.
