okay so for years i have shaved my legs, underarms and bikini but i seem to be having a reaction lately. my bikini has a heap of red bumps and my underarm skin has discoloured to a browny colour. i wanted to know if anyone had any suggestions as to what i can do to stop it. waxing is not an option as i'm allergic. also i can't afford anything really expensive

any suggestions would be amazing!
thanks
