The colour is buildable. For the desired colour result, you can apply the product onto your lips in layers. Use one layer for a soft touch of colour, two or three for a bolder look. Lip Sync also gives your lips a natural shine.
How to insert the refill in your case:
Open the case, take off the small, protective lid and simply insert the refill in the case. It clicks easily into place by means of a small magnet.
How to store the refills:
Do you own several Lip Sync refills? Ideally, you keep the refills that you are not using with your case, and protected against drying out and dust with the small lid that comes with it. A dry space at room temperature also works best for storing them.
