This, obviously, is undesirable.
One of the things that helps quite a bit is putting on one of these Etude House sheet masks when I feel one of these pimples coming on.
They're sized pretty generously for sheet masks, as you can see. Standard packaging too. One thing I always notice right away is that these are hella saturated. There's lquid all the heck over, and a lot in the package too. I'll take that over not enough liquid, but jeezy creezy, it seems like a waste having so much left in the package.
Also: this smells terrible. It works, but dear god, at what cost?
I can only recommend this to people who have awful, painful pimples like me. If they're sort of annoying, don't bother - get something that doesn't smell like a tea tree is exploding in your nose. But if they hurt, if they make you want to rip your face off, go for it. Just don't say I didn't warn you.
I got these from KoreaDepart for 10.00 for five of them USD, so about two bucks each before shipping. If you only want one or so at a time, pretty much any korean reseller should have these.
