A Single-Center, Open-Label, Prospective Study of a 589/1319 nm Dual Wavelength Laser for the Treatment of Facial Hyperpigmentation.

BACKGROUND

Facial hyperpigmentation, characterized by the excessive production of melanin in the skin, is a prevalent dermatological concern affecting individuals of various ethnic backgrounds.

AIMS: To evaluate the safety and efficacy of a multi-wavelength 589/1319 nm dual-pulse duration laser device for the treatment of hyperpigmentation Patients/

Methods

A total of 17 healthy women (mean [SD] age of 43.4 [11.6] with skin phototype II-IV) were enrolled in this prospective, single-center study. Eligible participants received up to 3 treatments spaced 3 to 5 weeks apart with 2 follow-up visits at 4 and 12 weeks after the final treatment. Assessments included investigator ratings of skin quality, global aesthetic improvement, and hyperpigmentation. Safety and tolerability were monitored throughout the study.

RESULTS

Significant improvements in hyperpigmentation and skin quality were observed at the 2 follow-up visits from baseline in most patients per investigator assessments. Patient satisfaction was high, and treatments were safe with transient self-resolving side effects such as erythema.

CONCLUSIONS

Laser treatments using a dual-wavelength 589/1319nm device significantly improve facial hyperpigmentation in patients of various skin types. J Drugs Dermatol. 2024;23(11):943-947. doi:10.36849/JDD.8196.
