I have tried everything! From expensive sunday riley products to estee lauren to clinique. But cosrx has really helped me with my acne prone/oily skin. I have stubborn blackheads but i used to always have 1 pimple.. i never experienced a face with no pinple at all.. even while using the aha/bha toner. But once I started to use this one, i only get a pimple when getting my period, and for the rest of the days, im glowing!
