Objective:
To compare the clinical efficacy, safety and pain associated with the use of the LightSheer Duet HS as compared to the original LightSheer ET diode Laser for axillae hair removal in Chinese women.
Methods:
Thirty-six Chinese women received three axillae laser hair removal treatments using the LightSheer Duet HS on one side and the LightSheer ET on the other side. Subjects were evaluated for hair removal efficiency. The immediate pain associated with the treatments was noted.
Results:
At 1 month following the final laser treatment, hair reduction on the LightSheer Duet HS side and on the LightSheer ET side was 81 ± 13% and 85 ± 9% respectively. There was no statistical difference. Immediate pain scores at the first session on the LightSheer Duet HS sites and LightSheer ET sites was 5.71 ± 1.74 and 6.86 ± 1.80 respectively, which was statistically significant (p < 0.05). Following the second and third sessions, immediate pain scores of the LightSheer Duet HS sites were both less than those of the LightSheer ET sites, but the differences were not statistically significant.
Conclusions:
The LightSheer Duet HS laser is a safe and effective method of hair removal in Chinese women. Treatment with the LightSheer Duet HS causes less pain.
