Introduction: Diode laser and intense pulsed light are among the most frequently used technologies for epilation. Objective: To compare diode laser with intense pulsed light in axillary epilation. Methods: Patients with phototypes II and III (n = 15) were subjected to 3 regular sessions of intense pulsed light (695 nm) - Quantum HR® Platform (Lumenis, Yokneam, Israel) in the right axilla and diode laser (810 nm) - Light Sheer® (Lumenis, Yokneam, Israel) in the left axilla. The number of axillary hairs were counted before and after treatment, and patients were administered a questionnaire about adverse effects, pain and satisfaction. Results: Both techniques provided a similar and significant reduction in hair density. The pain score and degree of inflammation were significantly higher for intense pulsed light (p < 0.01 and p = 0.03, respectively). There was a significant correlation between the fluence employed, the severity of pain, and the degree of inflammation for the two techniques (p < 0.05). The patients considered the final results to be similar, however more side effects were attributed to intense pulsed light. There was no difference in the proportion of preference between the two methods (p = 0.80). Conclusion: The two techniques produced similar results, but the diode laser caused less pain and fewer side effects compared to intense pulsed light.
