(9a): Baseline appearance of acne scars on the right cheek of a 32-year-old female patient. (9b): Result 3 weeks after 3 treatments separated by 4 weeks with a fractional CO₂ laser, output power of 20 W, microbeam spacing of 600 µm. The re areas are typical of the post-acne redness seen especially in Asian skin types III/IV following treatment of acne scars, and are part of the wound-healing process where active revascularization is more clearly seen under an immature epidermis.
