Wishkamar, if u're cheeks turn really red then calamine lotion with help soothe them and so will aloe vera gel ( I keep mine in the fridge) Please see u're derm and ask him for anti-bio's it'll prolly be a 6-8 months course. If it's an occasional pimple before u're periods, just dab tea tree oil. If it flares-up often have it treated!
For the red/irritated skin a cucumber/aloe gel mask is ideal and so is a clay mask mixed with rosewater..
