Title: Treatment of Freckles (Ephelides) Concurrent with Hori’s Nevus (ABNOM) Using a Combination Treatment of QSwitched Nd:YAG 1064nm Laser with 660nm (RuVY) Laser


Ephelides and Acquired Bilateral Nevus of Ota-like Macules (ABNOM) are common skin pigmentations in Asian and Caucasians that have become a cosmetic concern nowadays. We hereby present the case of a 34-year-old Chinese lady with Fitzpatrick type III skin who presented with hyperpigmentation over bilateral cheeks and the nose for 20 years. We have diagnosed her to have ephelides concurrent with acquired bilateral nevus of Ota-like macules (ABNOM) based on her clinical presentation. She was treated with QSwitched Nd: YAG laser with a converted wavelength of 660nm (RuVY Touch) targeting ephelides and a wavelength of 1064nm targeting ABNOM. Her hyperpigmentation responded well to the Q-Switched Nd: YAG laser and were completely clear after 10 sessions of laser therapy. In conclusion, our findings show that combining Q-switched Nd:YAG laser treatment with RuVY 660 nm laser treatment is effective in treating patients with freckles (ephelides) concurrent with Hori's nevus (ABNOM).
