I had sclerotherapy done a year ago to remove a blue vein. This caused hyperpigmentation. The doctor used tromboject. How do I know whether my pigmentation is due to hemosiderin or melanin?
When I pinch the skin above the pigmented area, the pigmentation disappears. When I let go, it shows up again. Almost as if something underneath the skin is causing it to look brown. What can I do to get rid of the pigmentation faster and is there a different solution I should use next time?
