Hello, the picture is not clear enough. If it is pigmentation caused by depilation, it will disappear in 6~ 12 months. If you are not at ease, you can come to our hospital for treatment.

(Dr. Huo of Badachu Plastic Surgery Hospital solemnly reminds: Because I can't see the patient face to face, I can't fully understand the condition. The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
