Because lip lines are related to the facial muscles that you use to purse your lips, Botox injections can be used alone or along with injectable fillers to smooth lip lines.
Fillers for Lip Lines
One way to reduce or eliminate vertical lip lines is to replace some of the volume that has been lost from lips over time. Dermal -- or skin -- fillers can be injected into lips to make them fuller. These procedures are very similar to the ones used to give Hollywood stars their sexy pouts, except that the goal is to replace what Mother Nature gave you and gravity took.
One popular dermal filler is collagen. Collagen from your own body or from a donor can replace the collagen lost due to aging, filling in the lips and smoothing lines. The advantages of collagen are low cost -- it is relatively inexpensive -- and, if the collagen is derived from your own body, low risk of allergic reaction. Collagen treatments have an almost immediate effect, but they're a very temporary solution, lasting only about three months [source: ASAPS].
Another type of filler that can replace lost lip volume, tightening and smoothing skin, is hyaluronic acid. Several popular lip fillers used by cosmetic surgeons contain this ingredient, though the concentrations vary. These treatments are more long lasting than collagen treatments, lasting up to a year.
A third option is to have fat injected into your lips to reduce lip lines. You may be able to have fat from one part of your body (such as the stomach) extracted, treated and injected. This can reduce the appearance of lip lines and it can give your face a fuller, more youthful look overall. Fat injections can cause lumping or scarring, though, so talk with your surgeon about the risks versus the benefits.
If injection-type fillers don't sound good, however, there are other options. For more information, read on.
