Several outlets have reported on the best lip liners, with some focusing on specific aspects such as long wear, comfort, and precision, while others highlighted the best options for certain skin tones or age groups. The number of lip liners tested varies across reports, ranging from 28 to 50, and the number of top-rated products also differs, from 3 to 16. The reports suggest that there are various highly-regarded lip liner formulas available, but the specifics of the top recommendations are not consistent across outlets.
