Abstract

Abstract: Objectives: Laser therapy has become one of the mainstay treatments for improving signs of aging including wrinkles, large pores, and skin pigmentation. However, in patients with pigmented skin, an increase in complications including post‐inflammatory hyperpigmentation (PIH) has been noted. The purpose of this study is to investigate not only the safety profile of 755‐nm picosecond laser with diffractive lens array (DLA) at approximately 2250 pulses on the face in people with darker skin, but also to evaluate its efficacy in treating wrinkles and pore sizes after one treatment session among different age groups. Methods: This single‐center, retrospective study enrolled patients between age 22 and 65 with both facial wrinkles and enlarged pore sizes. A total of 46 patients (7 male, 39 female, mean age 43) with Fitzpatrick skin types III and IV were enrolled. Two independent data‐blinded dermatologists assessed and scored the improvements of patients' wrinkles and pore sizes using photographs. Results: After one treatment session, statistically significant improvements were observed in lateral canthal wrinkles ( p < 0.001) and facial wrinkles ( p = 0.014). In addition, greater percentage of the patients from the aged group (50–65 years) showed clinically significant improvement as compared with the younger group. Conclusions: For patients with type III and IV skin, one session of DLA picosecond laser treatment at around 2250 pulses to the face is safe and effective for clinically meaningful improvement of the wrinkles and pore sizes, especially for the patients from 50‐ to 65‐years of age.
