Objective

The aim of the study was to evaluate the effectiveness and safety profile of alexandrite laser hair removal performed with the avalanche technique in conjunction with dry molecular cooling (DMC^™), and compare it with a hair removal treatment sequence combining both the avalanche and stamping techniques.

Methods

A cohort of 12 female subjects received 6 hair removal treatments in the axillary area using 755 nm alexandrite laser at 4-week intervals. The left axilla was treated only with avalanche mode in all sessions, while the right axilla was treated with avalanche mode in the first three sessions, and with the stamping technique in the last three sessions. Patients were followed up to 6 months after finishing the treatments. Effectiveness was evaluated by blind evaluation of before and after photographs, using the Global Aesthetic Improvement Scale (GAIS). Patient-reported measures – patient global assessment of improvement (PGI-I), pain during treatment and adverse effects were also assessed.

Results

Both treatment modalities have shown similarly high effectiveness, with the avalanche modality being more comfortable to the patient. There were no adverse events reported.

Conclusion

Hair removal using alexandrite laser in avalanche mode in conjunction with DMC^™ cooling is a highly effective, safe and durable method for laser hair removal.
