What are the treatments to fade a hyperpigmented scar that is purple that you are trying to fade to white? scars are over 2 years old.

See a dermatologist: Who can examine your scar and suggest the best therapy for your needs.

Vascular: The purple color in scars comes from blood vessels. At 2 years the scar is mature, and less likely to change on its own. Most topical treatments will do nothing, but a trial of topical silicone sheeting may help. Laser treatments can be used to reduce the size and number of blood vessels, or the scar can be excised and closed again. Which does or doesn't apply depends on your physical examination.
