Effectiveness of 675 nm Laser in Melasma Treatment: 1-Year Follow-Up.

Background

Melasma is a cutaneous pigmentary condition, difficult to treat due to its multifactorial chronic nature and high recurrence rates.

Objective

To investigate the medium-term and long-term efficacy of the 675 nm laser for the treatment of facial melasma with pigmentary and vascular symptoms.

Methods

Eight patients with facial melasma and Fitzpatrick phototypes III to IV were recruited. Three sessions were carried out with a 675-nm laser device. At 5 months and 12 months after the last treatment, the patient's skin was evaluated from baseline using a five-point Global Aesthetic Improvement Scale (GAIS).

Results

The study findings revealed a better overall appearance of the skin condition, in particular GAIS improvements mainly in the visible and pigmented components.

Conclusion

The 675-nm laser appears to be effective when treating patients with Fitzpatrick phototypes III to IV for facial melasma, with promising long-term results.
