Lasers to Treat Hyperpigmentation from Sclerotherapy?

Darkening of the skin after sclerotherapy could be post-inflammatory hyperpigmentation but often this fades before a year and a half. If you see a board-certified dermatologist they may use a Wood's light to see if the color decreases which indicates a deep pigment such that lightening creams will not work. Lasers may improve the darkening but they can possibly risk burning the skin or just irritating it enough to stimulate pigmentation, so you get or worsen the condition you're trying to make go away! The other cause for darkening after sclerotherapy is iron deposition in the dermis from leaks of blood or if the tiny clots that occasionally are left in the vessel cause staining from the red blood cell iron, similar to a tattoo! The 1064nm. NdYag laser may help, but remember, there is always a chance it may worsen it. You could ask the doctor to do a test spot rather than treating all the spots that bother you in case it doesn't produce a good result.

There is no perfect solution for post sclerotherapy hyperpigmentation.  Q-switch laser and Nd Yag laser have had some success.  Most hyperpigmentation post sclerotherapy will spontaneously resolve and some could be permanent.  Avoid sun exposure in the hyperpigmented areas

The Nd YAG laser may help but PIH (post inflammatory hyperpigmentation) can be reduced if you follow a regimen of wearing stockings for 3 months after sclerotherapy and also using 2 creams to reduce this hyperpigmentation. I recommend Slerovase and Scleroquin plus creams as well as Scler-x. Scler-x is post-inflammatory hyperpigmentation reliex complex.
