Laser Hair Removal
Are blisters normal after laser hair removal? Second treatment
Unfortunately, it looks like the settings used for your treatment were not appropriate for your skin. Follow up with your clinician to get the proper treatment to minimize risk of infection and scarring. Avoid sun exposure on the area until fully healed.
Clinical Context
Laser hair removal targets melanin in the hair follicle, using heat to disable it and slow future growth. Nearby skin also absorbs some of that heat. If the laser settings are too strong for your skin's melanin level, the skin can overheat and blister — a burn reaction, not a normal treatment response. Blistering should be evaluated promptly, kept clean and moisturized, and protected from sun exposure to reduce the risk of scarring or pigment changes.
