Treatment of benign hyperpigmentations and pigmented scars by 755 alexandrite laser comparing the Single Pass versus MultiPass (MoveoPL) emission in skin types I‐IV

Abstract

Lasers are effective treatments for benign hyperpigmentations but may be difficult especially in darker skin type. In this randomized split‐face controlled study on benign hyperpigmentations and pigmented scars, we compare the standard Single Pass (SP) emission with the MultiPass emission (MoveoPL) 755 alexandrite laser. Patients, skin types I‐IV, with solar lentigines and ephelides of the face, chest, and hands and patients with pigmented scars of the legs, underwent laser treatment, by treating one side of the body or half scar using the SP and the other side using MoveoPL. Improvements according to a grading score system, side effects, and patient satisfaction were recorded. About 63 patients were enrolled. An overall improvement of benign hyperpigmentations and pigmented scars was recorded, with a grading score (±SD) of 2.8\u2009±\u20090.8 for SP and 3.6\u2009±\u20090.5 for MoveoPL (range, 0‐4). SP emission showed best results in skin types I‐II whereas MotusPL obtained successfully results in all the phototypes analyzed (types I‐IV). Patients preferred MoveoPL as it was associated with fewer side effects. Both standard SP and MoveoPL emission are effective and safe. MoveoPL showed a higher efficacy and safety profile for the treatment of hyperpigmentations.
