There are minimal risks attached to fractional laser resurfacing such as:
Swelling: Post-procedure may occur. If it lasts longer, then the doctors may prescribe steroids to stabilize the patient.
Prolonged Redness: Redness and discomfort at the treated sites may last but eventually, settle down.
Hyperpigmentation: The treated skin might get darker. In such a scenario, the doctor will recommend a bleaching solution.
Burning: The surrounding skin of the treated area might have a burning sensation. It can be soothed with an ointment.
