case_images: A 59-year-old woman with moderate melasma primarily affecting her cheeks. She had previously undergone multiple treatments, including laser therapy and chemical peels, without significant improvement. Figure (a) shows the patient's skin condition at baseline, with MASI scores of 15.60 (Dermatologist 1) and 17.20 (Dermatologist 2). Figure (b) illustrates the notable improvement at the 12-week follow-up, where the MASI scores decreased to 10.80 (Dermatologist 1) and 13.40 (Dermatologist 2) after three sessions of poly-d, l-lactic acid injections. The patient reported a substantial reduction in hyperpigmentation, a more uniform skin texture, and high satisfaction with the results. Mild edema observed post-treatment resolved spontaneously without complications.
