Hyperpigmentation in the lower legs, areas which we call the 'gaiter areas' of the legs is the typical areas where there is staining of the skin with pigment and this is due to longstanding UNTREATED venous insufficiency.
It is never too late to initiate treatment and such treatment includes wearing stockings, getting evaluated with Duplex vein scans and treating sources of venous insufficiency.
Ancillary techniques to reduce hyperpigmentation includes the use of 2 topical products called Scleroquin plus and Sclerovase (see link below). These are cremes and will have to be applied topically for AT LEAST 1 year - the bronzing did not occur overnight and it will take more than a year for it to go away - at least 2 cycles of skin growth, each cycle being 180 days.
We also recommend the use of the oral supplement Scler-x. Scler-X is an anti-inflammatory hyperpigmentation relief complex which should be taken for 3 months to six months after tretment.
