[Effectiveness and safety of long-pulsed Alexandrite laser for hair removal in 1702 patients].

Objective: To evaluate the effectiveness and safety of long-pulsed Alexandrite laser for hair removal.

Methods: Hair removal was performed in 1702 hirsute patients with long-pulsed Alexandrite laser. Among them 1603 patients received two or more operations.

Results: In patients who received 2, 3, 4, 5, and > or =6 operations, the effectiveness rates were 9.79%, 18.33%, 29.10%, 37.64%, and 82.68%, respectively. The number of operation correlated with the effectiveness, and > or =6 operations resulted in superior outcomes. Pigmentation occurred in 0.94% of the patients (16/1702).

Conclusion: The long-pulsed Alexandrite laser system is effective and safe in removing hair.
