If you're game for a professional treatment, but you're not quite ready for needles, try Perk Lips, $29.95. An aesthetician will use a special machine to infuse serum into your lips for an immediate plumping effect. Then, you get to take home a vial of the serum -- in a nifty roller pen -- to keep the results going for a month.

Lip lines -- the ones around the border of your lips -- are the worst. They make lips appear thinner than they really are, and they create tiny rivers that pull lipstick away from where it belongs. Arbonne Intelligence Lip Treatment, $38, addresses them specifically with an ingredient called phytinol. It strengthens the lip barrier and minimizes those lines over time.

Epionce Anti-Aging Lip Renewal, $20, contains natural extracts like avocado, safflower and apple that work together to soften and hydrate lips. This silky balm also fills in lip lines instantaneously -- making it an ideal primer for lipstick.

If you're willing to wait 30 days, LifeCell Lip Plumping Treatment, $49, promises lips that are 40 percent fuller (according to a clinical study). It contains peptides that stimulate your own lips to produce more collagen while moisturizing and minimizing wrinkles.

Lancer Volume Enhancing Lip Serum, $40, gives you the traditional lip plumper tingle (thanks to Sichuan peppers) for immediate blood flow and volume. Over time, it hydrates with coconut oil and protects the lips from free-radicals (think UV and pollution) with dragon's blood (an Amazonian herb).
