Ahead, browse our collection of best lip moisturizers for a thirsty pout. Finally, other lip-enhancing formulas include active ingredients like salicylic acid or peptides; these would fall more under the “lip treatment” umbrella since they’re meant to treat various lip concerns (like, say, lip lines). Like its name suggests, a lip moisturizer’s main purpose is to focus on, well, moisture. Our high standards also come from testing products—many, many products. Our editors and writers rigorously test and research the products featured in our roundups to offer you the best, most informed recommendations. When we write reviews, you can trust we spend quality time with the formulas: We don’t simply rave about products we’ve slathered on the back of our hand. We endorse products we’ve tried and loved.
