Background Melasma treatment remains challenging despite various laser systems available, because of potential side-effects and high recurrence rates. Objective Non-ablative fractionated photothermolysis (FP) is a promising therapeutic method, long-time results comparing treated vs. non-treated site are lacking. Methods A total of 14 patients were treated with FP in a split-face mode with standardized adjustments in three sessions (weeks 0, 3-4, 6-8, follow-up: 26-28). At each consultation, improvement was evaluated by patients and physicians. Objective assessment was performed using digital photographs and the pigment imaging tool SIAscope(®). Results Melasma improvement was registered in 83% and 75% of the cases 26-28 weeks after the first treatment based on two evaluations: by patient and by physician, respectively. Digital photography and SIAscope(®) revealed improvement in 54% and 85% after the first, 61% and 85% after the second, 41% and 58% after the third treatment, accordingly, mostly due to reduction of the outline sharpness. Patients with lighter skin complexions revealed significant improvement ranged from slight to moderate (P = 0.03). Postinflammatory hyperpigmentation occurred in two cases with skin types III and IV. Conclusion Non-ablative FP can be considered as a valuable treatment option with short-term improvement in terms of mild reduction and softening the edges of melasma in patients with skin types I/II, if prior topical therapies failed. Treatment of patients with skin types III+ should be critically questioned.
