The main dangers of eyeliner washing are that it may cause localized infections in the eyes, and it may also burn the skin of the eyes, causing it to become sensitive. At present, the more commonly used method of eyeliner washing is laser eyeliner washing, which is to remove the eyeliner by laser energy acting on the eyeliner area and destroying the pigment, thus achieving the effect of removing the eyeliner. Generally, if you go to a regular and qualified hospital and choose an experienced doctor to operate, the safety will be improved. However, patients may be harmed by improper operation, such as if the operation process is not strictly sterilized, it may lead to bacterial infection of the eye, and redness, swelling and hot pain in the eye will appear. If the doctor does not control the laser energy, it is possible to burn the skin of the eye, making the skin more sensitive. It is recommended that patients in need of eyeliner washing visit a regular medical institution to assess their condition and perform the correct operation under the guidance of the doctor.
