Treatment of light - colored nevus of Ota usually involves laser therapy.
Q - switched lasers are commonly used. The laser energy is absorbed by the pigment in the nevus cells. This causes the pigment to break down into smaller particles, which are then removed by the body's immune system. For light - colored nevus of Ota, multiple treatment sessions may be required as the pigment is less concentrated compared to darker ones.
Another approach could be the use of intense pulsed light (IPL). It can also target and break down the pigment in the nevus. However, it's less specific than laser treatment. During and after treatment, it's important to protect the treated area from sunlight to prevent hyperpigmentation. Also, proper skin care, like keeping the area clean and moisturized, helps in the healing process and improves the overall treatment result.
