Eyebrow tattooing is essentially an invasive skin coloring procedure that uses a tattooing device to implant color into the skin to create a new eyebrow shape that will not fade over time. Eyebrow tattooing is usually not harmful to the body when performed by a professional physician at a regular institution. However, if the tattoo artist does not strictly sterilize the eyebrows before tattooing and does not follow the aseptic procedure, or if the applicant does not take proper care of the eyebrows after tattooing, local infection may occur in the eyebrow area, resulting in symptoms such as pus and skin necrosis. In addition, if the material used for eyebrow tattooing itself is not proper or compliant, it will not only stimulate the local skin and cause pigmentation, but may also cause allergies and red itchy symptoms. If the operator does not operate properly, the hair follicles under the skin may also be damaged, causing localized deformation and dislocation of the eyebrows. Embroidery is a typical medical cosmetic procedure and cannot be carried out in beauty salons without the consent of the relevant authorities. Therefore, it is usually recommended that people who need eyebrow tattooing go to a regular medical institution and have it done by a professional doctor to avoid unnecessary side effects.
