Whether false eyelashes can be reused depends on the specific situation. If it is a disposable false eyelash, it cannot be reused because these false eyelashes are coated with glue. Repeated use can cause local bacterial infections and, in severe cases, may lead to corneal ulcers and damage. If it is a reusable false eyelash, the original glue can be removed before the next use and the new eyelashes can be pasted again. However, it should be noted that reused false eyelashes can easily become rough, lose their original smoothness, and have a shorter lifespan. Therefore, when choosing fake eyelashes, one should choose disposable or reusable ones based on their own needs and budget. Attention should be paid to hygiene during use to avoid eye infections.

For reusable false eyelashes, the harder the material, the less likely it is to deform, and the more times it can be reused. On the contrary, the softer the eyelashes, the easier they are to deform and the fewer times they can be reused. For example, artificial eyelashes made of nylon or plastic can be used about 20 times if properly maintained.

When applying makeup, if the eye makeup looks good, the overall makeup will appear more natural and complete, and it can also have a magnifying effect on the eyes. Therefore, many girls choose to apply fake eyelashes when applying makeup.

Moreover, many people simply tear off their false eyelashes when removing them, which is actually incorrect. Because this will pull the eyelids, long-term tearing can easily make the eyes become flaccid. The second is that if the pasting is not good, it will make the real and fake eyelashes stick together, making it easy to tear off one's own real eyelashes as well. The third reason is that directly torn false eyelashes are prone to deformation, which reduces the number of times they can be reused. It is easy to use them once but cannot be used again.
