Lip primer is one of those skincare-meets-makeup categories that mostly underwhelms. Guerlain‘s KissKiss Lip Lift is the rare exception — a smoothing, plumping base that genuinely improves the look of every lipstick that goes on top.
What it does
Fills in fine vertical lines, smooths flaky patches, and gives lipstick something to grip. The pencil-style application targets the lip itself rather than spreading the formula past the natural line.
How it wears
Apply, wait 30 seconds, then lipstick. The difference is most obvious with matte formulas, which usually exaggerate dryness — KissKiss erases that effect. Wear time on the color extends by about an hour, in my testing.
An obsession worth the splurge if you live in matte lipsticks.
