Is laser treatment for nevus of Ota effective?

Currently, laser treatment is the most common and relatively effective method for treating Nevus of Ota. However, when using these methods, you should also pay attention to the indications. Laser treatment is more effective for shallower and lighter Nevus of Ota.

Indications

1. For lighter and paler nevus of Ota, pink and clean tissue can be seen after the first laser treatment of nevus of Ota; while deeper nevus of Ota will produce some scabs, and black and red skin lesions can still be seen after the scabs fall off. 15 days after laser treatment of Ota nevus, pigmentation gradually appears on the fresh tissue. The pigmentation is most obvious around 30 days. After that, the pigmentation gradually fades. Most of it disappears completely after 3 months. The complete disappearance period is more than 3 to 6 months.

2. For deeper nevus of Ota, the red bleeding area will dry into black blood scab the day after laser treatment. Some people may also experience slight swelling in the treated area.

3. The time of scab removal after laser treatment is different. For some people, it may take 10 days after treatment for the scab to fall off completely. During the scab removal period, it is forbidden to pick the scab and wait for the scab to fall off naturally.

Advantages

The advantages of laser mole removal are first reflected in the treatment method of this method. The laser technology it uses is an advanced cosmetic plastic surgery technology. The principle of the operation is to use the laser to burst out huge energy in an instant to act on the pigmented tissue, so that the pigment is broken and decomposed, and is swallowed by macrophages and discharged from the body with the lymphatic circulation, thereby achieving the purpose of removing pigment. Careful care after treatment will not leave scars. The traditional use of corrosive silver bromide, alkali or hibiscus cream is not recommended because it easily leaves pits and scars. Laser mole removal uses laser beams to directly destroy mole cells. The treatment process is short, the pain and wounds are very slight, and it is not easy to leave pigment scars. It is a powerful tool for treating some small flat moles.

Surgery must remove melanoma cells in layers and stages

However, laser mole removal is also safe, so it takes multiple times to completely remove the mole. The surgery must remove the melanin nevus cells in layers and stages, and often requires several treatments. The interval between each treatment is two to three months, and an average of two to three times. In fact, if a small, inconspicuous black mole is deep in the tissue, it may require up to four or five laser treatments. The most common laser mole removal is ruby ​​laser. This light wave targets black and brown pigments. The spots can absorb this type of laser and be decomposed. When the pigment is gradually absorbed by the body, the color also becomes lighter. Tattoos and eyebrow tattoos belong to this type of pigment. Other vascular spots such as hemangiomas can be treated with dye lasers. The hemoglobin in the blood vessels absorbs the laser and generates heat to shrink the microvessels, and the skin gradually returns to normal.
