Saemmul face lightener is basically a color corrector. If you're familiar with how color corrector works, you know that green is good for zapping redness. So far it blends in quite nicely and has done a great job of toning down the redness on my nose and cheeks. It is very light weight so should not clog pores. I've not had any break outs so far. Bonus:Also has SPF 30
cons: may not work well for dark or medium skin tones. Some say it left a white cast on their face.
