Yes, with any laser treatment, there are always risks and the possibility of side effects.  Discomfort during the treatment, redness, swelling and a heat sensation are all normal responses immediately after the treatment.   Blistering may occur within 48 hours after your treatment and may last 4-10 days, depending on the severity, followed by crusting/scabbing. It is important to not disturb the area during the healing process to avoid possible scarring. Please refer to our Pre and Post Treatment Information located on our tattoo removal web page to read all of the possible risks and side effects  associated with laser tattoo removal.
