I've tried the HERA, Missha, and SKII and this is my favourite so far. From the first time i used it, it left my face feeling soft and supple instantly. I bought this originally because for the brightening effects, which I think i has helped but I am also using other products to combat acne scars so it is hard to say how effective this product is alone. This did not break me out and instantly soothes my skin when it is feeling a bit dry and irritated. Although it is a bit expensive I will continue to repurchase this unless they change the formula.
