hi unfortunately some people can get scarring” after shingles goes away. you want to avoid sunlight because the sunlight can change the colour of the skin as it is healing. but avoiding sunlight is no guarantee that you will not have shingles scars which appear as white marks on your skin in the area where the shingles rash used to be. do hope this helps. good luck
is exposure to direct sunlight good or bad for shingles?
