The study will be conducted by using a fractional carbon dioxide laser for acne scar treatment. After the treatment, each patient enrolled will be applied 2 mL PLT solution on the right face. Treatment mentioned above will be repeated every 3 to 4 weeks, overall 4 times treatment and one month follow up after fourth treatment. Every record will be documented in questionnaires by the principal investigator and the patient itself. Moreover, VISIA is applied for objective observation, such as spots, wrinkles, texture, pores, UV spots, brown spots, red area, and porphyrins could be objectively analyzed.
