11. Ignoring Lip Liner

Neglecting to use lip liner can cause lipstick to bleed into fine lines around the mouth, making lips look less defined and accentuating signs of aging. A neutral lip liner not only outlines the lips for a more polished appearance but also acts as a barrier, preventing color from feathering.
For added longevity, fill in the entire lip with liner before applying your lipstick or gloss. This simple step enhances shape and keeps color in place. For more tips on avoiding lipstick feathering, consult Prevention’s guide to preventing lipstick bleeding.
