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

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

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

Methods: 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).
