Helps reduce inflammation and does draw out gunk from pimples but sometimes after leaving it on for the entire day it seems to kind of melt on the skin which makes it a bit of a nuisance to take off as it leaves sticky residue on the skin. I think it’s probably due to the heat and humidity but none of the other pimple patches I’ve tried has done this so I find it quite strange. I much prefer the Pyunkyung Yul super thin acne patches over these ones.
