I only get pimples on my forehead, in the forms of large, cyst-like zits. I use benzoyl peroxide and salicyllic acid as well as a general sensitive face wash, but it seems that after one goes, another comes up near it or around it.
I also get small, pus filled pimples on my scalp, sometimes they are irritated, and swell, other times they are simply just a pimple, anything to do about these?
I do pop them as well, the ones on my forehead and scalp, what can I do to further remedy these?
Pic related is my forehead.
