The best treatment for this is fractional laser, with prp and microneedling. Laser resurfacing has the ability to worsen this. Excimer laser sometimes works but is better for vitiligo than from skin damage. Please see a doctor with experience for this. Best, Dr. Emer.
Halo Laser would be a good consideration for uneven tone. Halo Laser can be combined with a hydroquinone based medical grade skin care such as Obagi.
