Was browsing Gmarket and come across this pimple product. it's seems to be pretty effective and the review is quite good. pricing is still quite reasonable - $16.90. so i decided to give it a try. however i tried for 5 days, applying the free sample - snail serum, then the pink liquid. but there is totally no improvements at all. i took photo of my serious breakout on day 1 and day 5 so that you can see the "difference"
