Cosmetics companies like Lipchic and Benefit sell products that seal your lipstick to make it smudge-proof. These sealers can cost anywhere from $12 to $30, which is a big expense when you consider that you paid the same amount for that tube of lipstick. Fortunately, you can make your own lipstick sealer for less than a penny.
Apply the chosen lipstick.
Get an ice cube from the freezer and hold it between your index finger and thumb.
Rub the ice cube over your lips to seal the color.
