The Always Sharp Lip Liner from Smashbox is a game - changer. It's a long - wearing and water - resistant lip liner that automatically sharpens itself every time you twist the cap off. You can easily sharpen, shape, and sculpt your lips to achieve a legendary look. It's available in a gorgeous Shocking Pink color.

Using this lip liner is super easy. First, twist the cap off, and the liner will self - sharpen. Then, outline your lips starting from the cupid's bow and follow the natural shape of your lips. You can also fill in your lips for a more intense color. Remember to keep the liner away from extreme heat as it might affect its self - sharpening function. When not in use, make sure to keep the cap on to prevent it from drying out. This lip liner is low - maintenance, just keep it in a cool, dry place and it'll be ready for your next makeup session.
