The product does not really do anything special, but it is those kind of products where you would have to use for a while to see some change to your skin. It does not really get rid of those black heads, however BHA is meant to use to clean your pore (of course after getting rid of the gunk clogging your pores). From my experience, it does not really get rid of or prevent pimples and such. However, what this product does do is evening out you skin texture. In other words, it helps smooth your skin by getting rid of dead skin cells sitting on top of your skin. Giving this product a three star because it didn't really do all that it claimed, but then again, you would have to use this product in a longer time frame in order to start seeing results (like even skin texture). Also, it does not disturb your skin in any way--no skin irritation of such from this product.

Keep in mind that Korean products are capped at certain BHA levels, thus the BHA capabilities does not play out as it should (as claimed). That is why using it long term might result something good for your skin.
