Short cut off filter IPL for treatment of lentigines in Asian Skin

Abstract

Intense pulse light (IPL) has been studied and was used to treat vascular and pigmented lesions. This study investigated the effectiveness of IPL using a short cut-off filter handpiece for the treatment of pigmented lesions in Asians. Eighteen Chinese female patients with skin type III-IV with freckles were recruited. They received up to 7 treatments with 1-month interval between each treatment. A single pass of IPL using the Starlux WhiteTM (Palomar Medical Technologies, Inc.) handpiece with wavelength of 400-1400 nm, along with spot size of 12 x 28 mm and maximum fluence of 100J/cm2 was used. There was a statistical significant improvement in pigmented lesions (p=0.034). 47.1% of subjects were moderately to significantly satisfied. In terms of treatment complications, post-inflammatory hyperpigmentation was recorded in 21.6% of subjects and one case developed hypopigmentation. (Reported by WM Au, GJ Chan and KF Loo)
