Q-switched ruby laser treatment of labial lentigos.
The Q-switched ruby laser causes selective damage to pigmented cells in the skin. This laser, which has a wavelength of 694 nm and a pulse duration of 40 nsec, has shown very promising results in the treatment of both amateur and professional tattoos. Less data are available on its ability to treat benign pigmented lesions of the skin. Three patients who had labial lentigos were treated with the Q-switched ruby laser, and dramatic clearing occurred after one or two treatments with a fluence of 10 J/cm2.
