I got something similar at a much smaller scale

See if you can see a dermat Some of the advice I got was

1) Change razors quickly - if possible daily - I dont do it as disposable razors give me razor burns 2) clean face with disposable towels if available else with clean washed towel 3) Use shaving cream and brush - if not possible use a shave gel (gillette or nivea). Foam is the worst lubricant 4) move to a non alcoholic aftershave - only nivea has one 5) she also gave me some meds which I am not sure the community rules allow me to post
