Use of a picosecond pulse duration laser with specialized optic for treatment of facial acne scarring.

Importance: Fractional laser technology is routinely used in the treatment of acne scarring, with thermal injury resulting in collagen synthesis and remodeling. Use of a picosecond pulse duration with a diffractive lens array may be a new technologic advancement in the treatment of acne scarring.

Objective: To investigate the safety and efficacy of a 755-nm alexandrite picosecond pulse duration laser with diffractive lens array for the treatment of facial acne scarring.
