Treating melasma with the 1064 nm Nd:YAG laser with a 650-microsecond pulse duration: A clinical evaluation.

Background: The effective treatment of melasma remains a challenge that necessitates a multifaceted approach that includes strict sun protection, bleaching creams, chemical peels, and laser therapy. The 1064 nm Nd:YAG laser with a 650-microsecond pulse duration provides a safe option for all skin types.

Methods: We treated 10 patients with the 1064 nm Nd:YAG laser with a 650-microsecond pulse duration. Treatments were performed every 2-4 weeks.

Results: Using a conservative treatment protocol, lightening of melasma occurred as early as 3 weeks post-treatment, with all subjects requiring several treatment sessions to achieve adequate resolution of their melasma. The majority of subjects experienced up to 25% improvement after two treatments, and an even more noticeable improvement after the 3rd treatment session. None reported any associated pain or discomfort.

Conclusions: Advantages of this laser modality include essentially no pain or downtime, lower risk of rebound, and the ability to safely treat all skin types with melasma. Therefore, the 1064 nm Nd:YAG laser with a 650-microsecond pulse duration serves as a treatment option for melasma.
