It is quite common for acne to leave red marks as they heal. These will gradually fade with time, provided active acne is treated and no new acne spots form. Lasers can be used to treat these marks to result in faster lightening.
I often use the VBEAM pulsed dye laser which targets such red marks very effectively. Most patients can expect 50-70% lightening after 2-3 sessions. The marks will initially look redder for 5-7 days immediately after treatment and then lighten over time. There are other lasers or even IPL that can be used to treat these marks but may result in a slower or suboptimal response. Hope this helps.
Warmest regards
