Can laser surgery effectively remove café-au-lait spots?

Generally, laser surgery may remove nevus of Ota, but the effectiveness may vary from person to person. The usual reference price for laser treatment ranges from 2000 to 5000 yuan per session, and noticeable improvement can typically be seen within 7 to 15 days. It is recommended to visit a formal hospital and undergo the procedure under the guidance of a qualified physician.

The principle of laser surgery for treating nevus of Ota involves using specific wavelengths of laser light to target the pigmented lesion, prompting the pigment particles to absorb the laser energy and subsequently be cleared and expelled from the body through a reaction process involving phagocytic cells. Laser surgery can efficiently remove nevus of Ota, restoring smooth and even-toned skin. It is relatively safe and generally does not cause damage to surrounding tissues.

However, if the nevus of Ota is particularly dark or covers a large area, the number of required treatment sessions may increase. The interval between each treatment is usually 3 to 6 months to ensure sufficient time for skin recovery and repair. After laser treatment, patients should take care to protect the skin from sunlight and follow proper skincare routines, avoiding UV exposure and frictional irritation to promote rapid skin recovery.

In addition, it is recommended that patients adjust their diet after undergoing laser treatment, avoiding excessive intake of spicy, stimulating, or greasy foods, and consuming more fresh fruits and vegetables to aid in skin recovery.
