I had my first treatment done using picosure. I've never had a reaction like this before but I'm sure it may be due to a better quality laser. I experienced a blister forming at the site but I kept the area moist and it completely resolved. I can feel scab like skin on the lower part of the tattoo but no peeling. The hyperpigmentation is what is most alarming as I had no blistering or hyperpigmentation with the previous 7 treatments (different laser). Is this normal?
