Eyebrow tattooing is essentially a kind of traumatic skin coloring technique, which is to use tattooing instruments to plant pigments in the skin tissues to form a new eyebrow shape that will not fade away for a long time. Its purpose is to use modern cosmetic means to cover up flaws, remove defects, enhance strengths and avoid shortcomings, modification and beautification on the basis of the original shape of the eyebrows to create a more ideal eyebrow, eye and lip shape, in order to achieve the enhancement of its local beauty and the overall beauty of the appearance. Generally under the operation of professional physicians in regular institutions, eyebrow tattooing will not cause harm to the body, usually no side effects. However, if the eyebrow tattoo artist does not strictly sterilize the eyebrow before tattooing, does not follow the aseptic operation procedure, or does not take proper care of the eyebrow after tattooing, it may result in localized infection in the eyebrow area, which may lead to pus and necrosis of the skin and other symptoms. Suitable people for eyebrow tattooing include those with sparse and scattered eyebrows; those with light eyebrows; those with incomplete mutilation, such as broken eyebrows and half-cut eyebrows; those with unsatisfactory original eyebrow shape; those with asymmetrical eyebrow shape; those with missing eyebrows caused by diseases and those with scars in the eyebrow; those with whitish eyebrows and eyebrow loss caused by diseases; those who need and are beauty enthusiasts; those who wear make-up or don’t have time to wear make-up; and those who are hairless after surgical eyebrow incision surgery. Tattooing is a typical medical cosmetic project, and beauty salons are not allowed to carry it out without the consent of the relevant departments. It is usually recommended that those who need eyebrow tattooing should go to a regular medical institution and be operated by a professional physician to avoid unnecessary side effects.
