DH is after some help. His face is quite prone to pimples but he looks after his skin well and they generally stay away. The problem comes when he has to work in certain areas in the heat.

He does machinery maintenance in a glass factory, and near the furnaces it gets seriously hot - today it's 45 there, and one section they're periodically trying to work on is 73 degrees. They take measures to try and keep safe and they're not in there long, but it's sweaty and dirty and dusty and it makes his forehead break out.

For some reason that's the only area, maybe because of his hat? His mate gets it on his back. Anyway, his entire forehead is bright angry red and just covered with big pimples. There's not a single part that isn't affected. He gets embarrassed by it and he puts cleanser etc on there like normal, but because he doesn't want it seen he's constantly pushing his hair down over it which I think can only be making it worse.

So I'm trying to get him to keep it uncovered and not touch it, but what else can he do?
