Keep water away from your lashes for the first 2 hours after application or touch-ups. The reason for this is to give the lash adhesive time to set the bond of the extension to your natural eyelash. The after-care varies depending on the glue used. It is also important to avoid crying or any other sources of moisture, such as steam or rain within the first two hours of lash application. With the use of premium Misencil adhesives you don't have to wait 24 - 48 hrs anymore!
