When it comes to nevus of Ota, you may be unfamiliar with it, but if you mention “green face”, you must have a vivid memory of Yang Zhi’s unforgettable face in “The Legend of Water Margin”. Or you may occasionally see a beautiful MM in your life, but it is only because of a mole on your face that makes people sigh with sorrow. Nevus of Ota is a very typical birthmark. It develops in infancy and grows as children grow up, and some people’s nevus of Ota has a tendency to increase slowly in adulthood. As nevus of Ota is usually located on the face, most people show greenish, greenish-gray, greenish-black or purplish-brown patches on half of the face, and some patients also have blue sclera in their eyes, which seriously affects the beauty and self-confidence of the affected children. In the past, due to the limited treatment methods for nevus of Ota, the effect of treating nevus of Ota is not ideal. Many patients choose to use various methods to lighten nevus of Ota for the sake of aesthetics, and some of them even seek medical help in a hurry and easily believe in advertisements and go to irregular hospitals to treat the nevus of Ota indiscriminately, leaving permanent scars on their faces. Here we would like to remind you that in order not to leave regrets, it is best to choose a senior professional dermatologist. The dermatologist will determine the diagnosis based on the color of the pigment, its distribution, whether it involves the sclera, and the necessary examinations. The most suitable laser instrument and the corresponding treatment parameters will be selected for the patient under a clear diagnosis. How to lighten nevus of Ota has been a hot topic of discussion in the past, and with the continuous passage of time, the methods of treating nevus of Ota have also undergone epoch-making changes. Removing nevus of Ota without scarring is no longer out of reach today. Nowadays, the treatment of nevus of Ota is mainly based on laser treatment. There are three types of common lasers for nevus of Ota treatment: Q-switched ruby laser (wavelength 694nm), Q-switched emerald laser (wavelength 755nm), and Q-switched Nd:YAG (wavelength 1064nm).
