Several kinds of laser treatments have been used on various skin lesions with some success. In the 1990’s, copper vapour laser was used to treat fibrofolliculomas on individuals with Birt-Hogg-Dubé syndrome in France. Several researchers have also described the use of carbon dioxide (CO2) laser treatments. Although apparently ‘successful’, without long-term follow up it is unknown how successful these treatments actually were. The chemical erbium produces a laser beam that is better absorbed by the skin than that of CO2 lasers, so theoretically it would be easier to target specific lesions without harming the surrounding skin. The Erbium: YAG laser technology has been used in combination with CO2 lasers to treat BHD fibrofolliculomas. This appears to produce better results than either laser used alone. You may find that different dermatologists have their own preference regarding laser types.
