Clinical observation of Medlite laser irradiation on freckles and lentigines

Objective To explore the clinical effect of Medlite laser irradiation on freckles and lentigines, Methods We treated 490 cases of freckles and lentigines with MecUite laser machine made in ConBio company, USA. The wavelength are 532 nm and 1064 nm. We chose proper parameter to treat the patients according to the skin character, and then irradiated to the eruptions. The skin turned white and radgy, which showed that we chose proper parameter. We could retreat the patients after a month. Results All of the 457 freckles in 490 patients were cured after 1 - 3 times treatments. The skin reaction to the laser irradiation is slight. About 15 % of the patients showed transient hyperpigrnentation or hypopigmentation, which could disappear spontaneously after 1 - 6 months. All of the 33 lentigines showed significant effect after 1 - 8 times treatments. Conclusion The effects of Medlite laser irradiation are satisfied with no scar and slight skin reaction on freckles, but not so satisfied on lentigine.
