Eyelashes are three-layer hairs growing along the edge of the eyelids. Eyelashes are very important for beauty because they protect the eyes from sunlight, debris, dust and small particles. They also serve as antennae because they are very sensitive to touch and alert the eye when an object, such as an insect, is near it.
Although this may seem like a stupid question, many people don’t know how many eyelashes they have. Some people think from 20 to 500. As you can imagine, this is more difficult than counting the number of peduncles on a flower. The amount of hair on the head is determined by various factors, including genetics, nutrition, health and personal care.
The lower eyelid has from 75 to 80 eyelashes, and the upper eyelid has from 90 to 160 eyelashes. The length of eyelashes varies from person to person; they do not grow beyond a certain length (usually less than 12 mm) before falling out on their own.
The number of eyelashes on one eye varies greatly, and this is where factors come into play. For example, a teenager’s eyelashes are naturally longer and fuller than those of more mature adults. Their regenerative properties are more active, which means that eyelashes grow and are replaced faster and are healthier than those of older people.
