Follow the natural lip line to define the shape, slightly overlining the cupid’s bow and centre of the lower lip for a fuller look. For a contoured effect, choose a shade one to two tones deeper than the natural lip colour or skin tone and blend, then finish with lipstick, gloss or balm. For a softer finish, diffuse the liner with a brush before layering gloss. For a fuller effect, apply the liner all over the lips as a base, then layer another lip product on top.
