about two weeks ago, i shaved and as always got a few ingrown hairs on my upper lip. ironically, the bad ones have actually dissapeared now and have left no mark. however, there was a small red mark on my upper left moustache area, so i put some toothpaste on it in an attempt to calm redness. i did this for three nights, however by night three it had filled with pus and in the morning it exploded, leaving an open wound. it then scabbed over, and i had to constantly moisten the scab and remove pus from it, however, when there was no more pus, i allowed it to scab over, applyed moisturiser to quicken up the scabbing process, and about five days later it fell off. i have now been left with a dark mark, which is very large and embarrasing. please can anyone suggest any treatments to lighten the mark.
p.s. how long will it take to fade, or become less obvious. a month?
