BACKGROUND: Although a 1450-nm diode laser has been shown to be effective for acne, the conventional high-energy stamp-only regimen is often associated with pain and hyperpigmentation, especially for dark-skinned individuals.
AIMS: To evaluate whether the novel dual regimen has clinical advantages for acne treatments compared with conventional regimen in Asian patients.
PATIENTS AND METHODS: Twenty-four Korean patients with facial acne were treated with a 1450-nm diode laser through a 20-week, randomized, split-face study. The patients were treated with three consecutive sessions at 4-week intervals. One half of the face received a dual regimen consisting of low-fluence stamping mode (5-6 J/cm2 ) for inflammatory acne lesions only, followed by 4-5 passes of moving mode for the full face. The other side received a single-pass treatment of conventional high-fluence stamp mode (14-15 J/cm2 ). Evaluations for acne, sebum secretion measurements, and safety profiles were performed.
RESULTS: At the final 12-week follow-up evaluations, the dual-mode side demonstrated better improvements in both inflammatory and noninflammatory lesion counts, acne severity assessments, and reduction in sebum secretion compared with stamp-only side. Subjective satisfaction for the improvement for acne, seborrhea, and texture correlated well with objective assessments. In addition, degrees of pain and treatment-related side effects were remarkably decreased in the novel dual mode.
CONCLUSION: This novel dual regimen of the 1450-nm laser demonstrated improved efficacies for acne and seborrhea with satisfactory safety profiles. Therefore, this regimen would be a viable option for acne treatments either as monotherapy or as combination therapy.
