Being a huge fan of the Pimple master patches by COSRX, I was really curious to try these ones.

I find like they work okay on those comedones under the skin, they help to make them "reassorbe" faster and the redness to fade.

My rank is not higher because they say you can use them during the day too, under your makeup, and while they're sure thinner than the red ones, you can still clearly see them on your face. I wouldn't go out with them on.

Also, I feel like you can acieve the same result with some tea tree oil or something similar, there's no really a necessity to buy them!
