In many cases, if you overuse them and do not apply them in a right way, it can lead to some serious eye diseases, such as the eye infection and pink eyes. Generally speaking, when you want to use them, you have to put eyelash extensions directly to the natural eyelash with a bonding agent. In that way, the bonding agents and glues, which are made of chemicals, can be irritants and cause discomfort and potential eye damage in severe cases. According to some doctors, it may lead to Traction Alopecia. It is kind of dangerous. Also, pink eyes, dry eyes can occur too. So anyway, you should pay more attention to it.
Well, it seems that you like to apply eyelash extensions for cosmetic purpose.So as a matter of fact, despite that they would make your eyes appear to be more attractive in the first place, however,there are always some side effects, if not properly handled.
