Freckles, dark spots and skin pigmentation can be caused by many factors including sunlight and environmental factors. Age spots, skin pigmentation and freckles are forms of pigmented lesions. They are caused by excess production of melanin in the skin. Candela gentle-lase has been used for many years with great success to remove pigmentation by emitting a charged energy light which is absorbed into the pigmented area, this light converts to heat, which damages the target cells without affecting the surrounding skin. After treating the pigmented areas they will go darker sometimes almost black, then will fall off within 7 to 28 days (depending on the area of the body) or it will just gradually fade.
