The use of picosecond laser in dermatology was originally focused on optimizing the removal of unwanted tattoos. Subsequent advances in this technology have broadened its clinical indications to include treatment of benign pigmented lesions, photodamage, melasma, and scar revision.

The aim of a recent study published in Lasers in Surgery and Medicine was to develop evidence-based recommendations regarding the use of picosecond laser in dermatology.

This systematic review entailed a comprehensive search of the English language literature was up to November 2019. With the addition of the authors combined clinical experience, clinical recommendations were developed.

Overall, 77 unique studies were evaluated. The findings revealed that the treatment of benign pigmented lesions was associated with level I-IV evidence; rejuvenation was associated with level II evidence; melasma was associated with level II evidence; scar revision was associated with level II-III evidence; and tattoo removal was associated with level I evidence.

In inference, it was stated that picosecond laser is a safe and effective treatment modality for an increasing range of dermatologic indications. Therefore, further development of this technology is warranted.
