Tattoo removal burn? Is this normal?

Yes, unfortunately it is common to have blistering after Laser treatment for tattoo removal.  It’s not so much from the heat of the laser but due to the incredible pressure caused by the laser over a picosecond burst of energy.  This blast of energy is what disperses the tattoo ink in the skin so that your body will resorb it, removing the tattoo.  Picosure is able to remove the tattoos in a shorter amount of time (fewer treatments required).
