Lip plumpers alone won’t give you bigger lips. Why? The skin on your lips needs to stretch and grow to accommodate more lip. We don’t live in a world of magic, and our bodies can only do so much. If you don’t let your lips gradually stretch, they won’t stay plumped, even with the best products. Not only that, but they’ll become incredibly uncomfortable and you’ll probably start getting dry crackly bits on them, and your lips will start splitting when you use plumping products. This isn’t a sign that the plumping products aren’t working, it’s a sign that you need a better lip care regime to enable your lips to plump to their largest.
