This will also depend on your lip shape, as those with a prominent cupid’s bow may have trouble blending a super dark liner compared to those with oval-like lips. 

You can also contrast a darker liner with a lighter base. “With that liner, outline and overdraw your lips, apply a lighter lipstick, and finish it off with some lip gloss to achieve an extra sensuous pout,” celebrity makeup artist and KVD Beauty Global Veritas Artistry Ambassador Anthony H. Nguyen tells mbg.

No matter which color you choose, be sure to hydrate your lips before applying your liner. Opt for a nourishing lip balm and use it 10 to 15 minutes before your lip liner and lipstick to ensure your pout is prepped and plumped with hydration. After all: Chapped, flaky lips easily can age your look.
