The Q-Switched Ruby 694 nm Laser allows us to treat pigmented lesions such as sun spots (lentigines), seborrheic keratoses, age spots, and birthmarks. The wavelength of the Ruby laser is thought to be the most effective in treating age spots and other pigmented lesions. NY Medical Skin Solutions is one of the few centers in Manhattan to have this device. After a treatment, the lesions will become darker after the treatment and gradually crust off over the next 10 days or so. Many of the darker age or brown spots will respond after just one treatment whereas some fainter or lighter spots may require another treatment.
