After enlist, go make appt to go NSC. Tell doc you want to take
isotretinoin (a.k.a accutane), an oral medication. That'll remove
all existing acnes, and prevent new ones. After acne problems
solved, there's a few options to lighten (or hopefully, remove)
scars. Cheaper ones include chemical peeling. More expensive ones,
laser treatment.
PS: NSF can get isotretinoin (about 2 bucks per pill) free. But
chemical peeling/laser treatments are not sponsored.
