I had laser treatment for a very small patch of facial thread veins a month ago. It blistered immediately and after 2 weeks the blister had scabbed and the scab fell off. However, i am now left with a red indented mark which looks to me like it is fully healed so i am worried it is now an ugly depressed scar! It looks worse than the small red vein i started with! The scab came off 2 and a half weeks ago and there is no scabbing, crusting etc any more - just a huge ugly red indentation in the exact shape the blister formed. It looks awful :(
