Using the Maqpro Lip Liker is super easy. First, make sure your lips are clean. You don't need to use any primer before application. Simply take the applicator and make one pass over your bare lips. Wait about a minute for it to dry. As it dries, you'll notice a beautiful matte finish. Remember, this lip liker is long - lasting, waterproof, and transfer - free. To keep it in good condition, store it in a cool and dry place. If you have any allergic reactions to lip products, it's a good idea to do a patch test on a small area of your lips first.
