Thanks for your question – which is one of the more difficult skin concerns that dermatologist see on a regular basis. The pigmentation that remains from having venous stasis is not easy to treat, and many of us would start with a mid potency steroid preparation to treat any of the underlying inflammation that may still exist. The use of compression stockings and leg elevation will also help some. Bleaching medicines may help a little, but it has been my experience that in the majority of cases, they do not. And lasers are problematic in many cases here – but you can try IPL in very skilled hands – it is not going to be a cure – but a fix, and if the stasis is not under control, then recurrence is pretty common.
