Are large blisters common after laser therapy?

I had laser therapy for the second time this past month and it was very painful during the procedure. Right away I developed large watery blisters that eventually turned into dark scabs. I have been soaking my legs in a bath for the past two weeks and using neosporin to fight infection.

The blisters broke and opened up. Three very sore areas became red around the lazer sites and inflamed. I called the drs' offcie 2 X and finally went up. The technician that did the lazer therapy took me into a room looked at my legs and said I looked normal. I was in a great deal of pain and did not like the red area around the sores. Finally after another week and not getting better, I called in and said I needed antibiotics becuse I feared I had a raging infection brewing. 

I am into the 24th day and still feeling discomfort. I have deep scabs and redness around some areas. I feel I was literally burned during therapy. How can this procedure be run of the mill as I was told?  Can you tell me if I am exeriencing a normal reaction or if something went wrong?

A: Blisters are NOT Normal after Laser Treatments

Harold J. Kaplan, MD

Your experience is not normal. Blisters are not a desired clinical endpoint for any of the laser treatments we provide and we have done 75,000 of them over the past 5 years with 10 different lasers. If your legs were being treated it's possible you were getting hair removal, spider veins or even brown spots.... more

The large blisters and scabs are not normal. typically any topical laser treatment for hair removal, pigment or blood vessel removal or non-ablative rejuvenation treatment produces reddness but no blister. Blisters indicate a burn which cna be caused by too much laser energy or by doing a laser treatment on... more

A: ??Neosporin Allergy

    While you might be having a reaction to the laser itself,  I would not dismiss the idea that you are having an allergic contact dermatitis reaction to Neosporin. This is fairly common and can cause blistering in those sensitive.     I would return to the physician who did... more

A: Probably Not Normal

What you are describing is not generally expected. As Dr. Wallach points out, there are some other pieces of information which would be helpful. I would suggest visiting with the overseeing physician for evaluation. With a lot of complications after laser therapy, the earlier the intervention you can make... more

A: Scabs after lasers

Steven Wallach, MD

It doesn't sound like you are having the "normal" experience. You did not report what type of skin color you have or what procedure you were having. Blistering can happen with some laser treatments for may different reasons.  It is not what you want to see with the lasers. ... more

I have had laser surgery on my portwine stain birthmark 10+ times, and that literally "burned" feeling during the surgery is perfectly normal. Watery blisters are normal and they usually stay around for a week or 2 sometimes more, but I play football and I tend to sweat alot which results in the blisters becoming filled with alot of liquid so they eventually pop. ya sounds nasty, and its not a pretty sight. After the blisters pop, it turns into scabs. And the scabs stay for a minimum of 1.5 more weeks, if the laser treatment was harsher then it lasts alot longer. I'm sure you are just overreacting. did u really have DEEP scabs
