Dark Spots on Legs. How Do I Get Rid of Them?

Dark scars on the legs are common and form from inflammation. The
process is known as PIH. In our office, we use a combination of
fractional laser, Melapeel Pink, and Luminase cream applied twice
daily.

Especially with a history of eczema, there is a liklihood of developing postinflammatory hyperpigmentation, thickening of the skin from chronic rubbing secondary to severe itching, and possibly iron staining of the skin from red blood cells that leak out into the dermis. All of these three situations can contribute to the darkening and they might be treated by different creams, or lasers. There is a risk of lasers making the pigment darker, and if there is a vigorous reaction you could scar and get permanent white centers with dark brown around the white. Keep searching for a dermatologist who is interested in trying many different treatments to see if something can safely help. Wrapping the leg might help, if the wrap is used to cover an emollient.
