The free-running ruby laser has recently been introduced for removal of unwanted hair growth. It is assumed that the mode of action of ruby laser depilation is that of selective photothermolysis of the melanin-rich structures. The present data reflects our results of ruby treatment of 133 patients attending a dermatological laser clinic for hair removal. When success of the laser treatment was defined as greater than 50% hair removal, 59.0% of patients reported successful results after 90 or more days after last treatment. With success defined as greater than 25% hair removal at 90 days, successful treatment was obtained in 75.0%. Also, the patients evaluated the overall result of their treatments. The percentage of patients who were either "very satisfied" or "satisfied" after 90 days was 64.2%. Only a few side-effects were observed. In general, pain was no clinical problem. No significant scarring was observed. A temporary hypopigmentation was experienced by approximately 10%, but only one patient still had hypopigmentation 90 days after treatment. Due to variability of hair density as well as anagen and telogen phase durations in different anatomical locations, firm conclusions regarding the long-term effect still cannot be drawn.
