Because the laser does not produce a break in the surface of the skin, risk of infection is minimal.
Hyper- and hypopigmentation
Hyper- and hypopigmentation can occur, particularly in patients with darker skin types. Hyperpigmentation is avoided and treated by strict avoidance of ultraviolet exposure, sunblock, and a bleaching cream. It can take several months to fade. There is a risk of lightening of the skin, particularly in patients with darker complexions. This is rarely an issue for patients, who may have some increased skin pigmentation in the affected areas anyway.
This is more likely in patients with darker skin types or tanned patients because more energy is absorbed by the skin. These blisters are superficial and unlikely to leave scars.
The risk of scarring is minimized by the use of appropriate energy settings.
