A YSL first, blur in a compact that perfects skin while retaining its luminous glow. It transforms from a balm to a powder upon application to blur imperfections and create a transparent, ever so slight rosy-glow effect. Instantly pores look visibly minimized, skin feels smoother and complexion looks more uniform. Use 3 ways: 1. alone as an allover complexion perfector 2. to set makeup 3. As a mattyfying touch up during the day to sweep away any shininess and imperfections.
