Broadband light treatment using static operation and constant motion techniques for skin tightening in Asian patients

Broadband light (BBL) devices irradiate photons of different wavelength to induce photothermal reactions on various aging-related chromophores.

To evaluate three BBL treatment settings for skin tightening in Asian patients.

A total of 27 patients underwent three sessions of BBL treatment via (1) an 800-nm cutoff filter using a static operation technique and a 695-nm cutoff filter using a constant motion technique (group 1, N = 9), (2) an 800-nm cutoff filter using a constant motion technique (group 2, N = 9), and (3) a 590-nm cutoff filter using a constant motion technique (group 3, N = 9).

The patients in group 1 presented marked clinical improvements in zygomatic wrinkles, nasolabial folds, and marionette lines, with a median overall global aesthetic improvement scale (GAIS) score of 3. Meanwhile, patients in group 2 exhibited noticeable improvements in zygomatic wrinkles, nasolabial folds, perioral expression wrinkles at the cheek, and marionette lines, with a median GAIS score of 3. Patients in group 3 experienced improvement in skin tone and texture, zygomatic wrinkles, nasolabial folds, and marionette lines, with a median GAIS score of 2.

Our data demonstrated that BBL treatment for nonablative, noninvasive skin tightening elicits satisfactory clinical outcomes.
