Abstract: Ephelides is a common pigmentation characteristic observed in both Asians and Caucasians which has become a concerning cosmetic problem. We herein present a case of 24 years old Fitzpatrick type III gentleman with more than 10 years of ephelides receiving 8 sessions of Q-switched RuVY Touch 660nm wavelength without additional topical or oral medicine. RuVY Touch treatment has a relatively weaker absorption rate by hemoglobin, lower the risk of vascular damage and associated post inflammatory dyspigmentation. However, the absorption in melanin is still high, although slightly lower absorption compared with the 532nm beam. Hence, the safety level for treatment of discrete epidermal lesions is increased, which means faster healing and less unsightly erythema and crusting, which is an advantage for the patient. In conclusion, our data suggest that RuVY Touch treatment, utilizing a converted wavelength of 660 nm, can be effectively used for the treatment for ephelides- freckles.
