Laser treatment is an effective treatment to consider if nothing else works. The heat energy of the laser targets the melanin deposits in your upper lip area and helps reduce pigmentation. Within a few sessions, you can notice significant results. Dermatologists schedule laser toning sessions at an interval of four weeks. Depending on the involvement and extent of pigmentation, the number of sessions may vary. Non-ablative lasers also reduce pigmentation in the upper lip area and have no downtime.
