DD is having a terrible time with blackheads on her forehead 
She's 15 and suffers with a greasy t zone. She doesn't wear make up at all.
We've tried gentle daily exfoliators, face washes, tea tree cleansers, face masks etc but nothing seems to work.
Tonight she's rubbed lemon and honey on her forehead. It was a tip from Pinterest. Her forehead now looks worse than ever (bright red patches) but we're hoping it settles down over night.
She has a squeezing session now and again and even lets me have a go
but I'm worried that we're just aggravating her skin.
Can anyone provide a good way of dealing with them?
