Using this lip tint is super easy. First, shake the bottle well to mix the color. Then, apply a thin layer of the tint directly to your lips using the applicator. For a more intense color, you can add an extra coat. When it comes to maintenance, keep the bottle tightly closed after each use and store it in a cool, dry place. And a little tip: avoid eating or drinking right after applying to make the color last longer. Enjoy your new lip tint!
