Eyelashes are made longer through professional application of an individual synthetic eyelash directly attached to the natural eyelash with a specially formulated bonding agent.
Normally a person's natural eyelash falls out every 60 - 90 days and a new lash grows in immediately. Therefore, it is necessary to get touch-ups to fill in the fallen lashes. About every 2 to 3 weeks is recommended, however, this will vary from person to person. Your natural lash cycle as well as how you take care of your lashes will affect how long they last.
If you wait too long to get a touch-up many of your extensions may fall off and you will need to have the full set re-applied.
The better you care for your eyelash extensions, the longer they will last and look beautiful all year round!
