Can't see the pictures, but it could be cystic acne.
Try an Elimination Diet of mostly raw green vegetables (steamed and lightly cooked is ok), few fruits (or none), and little wild/brown rice for a week. You want to avoid anything that jumps your blood Sugar and insulin up. Slowly introduce meat during the second week. Avoid all other stimulants like alcohol, caffeine, etc... like the plague if you really want to get rid of this thing.
Wash face 2 times, in AM and PM, daily with over the counter facial cleaner that's specificially for sensitive skin that does not clog pores. You can additionally spot treat it with an Acne cream medication (usually over the counter too).
Don't cheat your body or it may screw up the healing process by contaminating it with poor dietary choices. Report back in a week with progress...
