Semi-permanent eyelash extensions differ from that of false or strip lashes, as they are applied lash-to-lash.
One single, soft and synthetic lash is dipped in adhesive and applied to one natural lash.

The natural lash cycle is 45-90 days, meaning, as your lashes fall out and naturally replenish, the applied lash will fall out with it and this is what will be replaced during a maintenance session. Therefore, with regular maintenance, your lashes will last as long as you desire.

You will lay on a padded portable bed with head support to ensure you are completely comfortable throughout the treatment. It can take up to 2 hours (no longer) depending on the look you desire and the amount of lashes needed to create this look, although normally it takes no longer than 1 1/2 hours. On average 60 -80 lashes are applied to each eye. Your lower lashes will be taped out of the way during the procedure and a crystal-collagen gel eye pad will be placed  along the underneath of your eye for optimum relaxation. These powerfully reduce dark circles, puffiness and wrinkles and due to being enriched with moisturisers will prevent and refine ageing and refirm the area. So, you will not only end up with beautiful lashes, but more refined and replenished skin as well!

Your eyes will be closed during the treatment, so go ahead, relax and unwind while you can.
Falling asleep is common and perfectly acceptable.
