A reader asks: are lip lines best treated with the erbium laser? John Martin, cosmetic surgery and laser specialist based in Miami, responds.
A fiber laser or fibre laser is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, thulium and holmium. https://en.wikipedia.org/wiki/Fiber_laser
Erbium is being used more and more in the medical industry, particularly in dermatology laser surgery whereby an erbium laser is used for facial surgery to treat acne scarring, wrinkle reduction pigmentation and lesion removal as well as for the treatment of rhinophyma.
