Strivectin Nourishing Lip Plumper, $39, has both immediate and gradual results. Slap some on under lipstick, and your favorite red won't bleed or feather. After a few weeks of using it, lips will start to feel softer and look fuller thanks to hyaluronic acid and niacinamide.
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.
