I have a zit that hasn't healed in more than an year... It's a tiny zit in my forehead. It hasn't got any "altitude", it looks like a very tiny semi-open wound, but I can tell it's definitively acne. I never ever picked it up.
And now, like a month ago, I got a new one, in the corner of my nose, that is the same... it almost vanishes, them comes again with new sebum... and never heals

Do you guys know any good solution for this? Any herb/medicine/product perhaps?
