11 Days Left. Please Help With Ingrown Hairs On Legs And Pubic Area, Rash, And Acne?

Tweeze the ingrown hairs, use a facial wash for acne on your can (something with benzoyl peroxide or salcylic acid), I dont think I'd put any more lotion on your until you dry out the pimples. Use shaving cream and let your skin soak in hot water for 5-10 minutes before you shave and you shouldnt get a rash from shaving any more. If you start now, everything should be healed up before you leave.
