Treatment of pigmented lesions by Starlux-V handpiece

Abstract

BACKGROUND AND OBJECTIVES: Intense Pulse Light (IPL) has been studied and was used to treat vascular and pigmented lesions comprising photorejuvenation and is used in photodynamictherapy. The objective of the study is to investigate the effectiveness of Starlux-V handpiece for the treatment of pigmented lesions in Asians. DESIGN/MATERIALS AND METHODS: 20 Chinese female subjects with skin type III–IV with freckles were recruited in this prospective study. Each subject has undergone up to 6 treatments with approximately 1 month interval between each treatment. Each visit involves single pass of Starlux-V handpiece treatment. The wavelength of this handpiece is 400–700nm and 870–1200nm. Spot size 16_46mm with maximum fluence 25J/cm2. Subjects were evaluated at baseline and 1 month after each treatment by means of standardized photos using the Canfield Visia CR System1 and patient questionnaires. Any adverse effects were noted. RESULTS: Fine line/wrinkles and pore size had no improvement after treatments. However, there were mild to marked improvement in pigmented lesions. One subject developed post-inflammatory hyperpigmentation. That is 3 out of 103 treatment sessions-2.9%. Overall patient satisfaction was good. Some reported mild to moderate levels of pain during treatment. There was also subjective improvement in wrinkles and pore size. CONCLUSIONS: Starlux V handpiece is effective for treating pigmented lesions with a very low incidence of post-inflammatory hyperpigmentation.
