I had 8 seesions IPL on my upper lip for hair removal purposes only. (fair asian skin,dark hair). I had good results,after the last session on 6 OCT 2011, the next day I noticed darkening of my upper lip, I have only used aloe vera gel (can't get hydroquinine in UK it is illegal) now 1 month later the area is still SLIGHLTY darker, will this resolve with time? what should I do? I wear sunscreen every day and DO NOT want to have any more IPL sessions.
