In some cases the lines are active (i.e. present on contraction), though they can also be static (i.e. present at rest), appearing below and/or above the lips. However, treatment is very effective and quite simple.
Dermal fillers are injected into the perioral area to plump out and smooth the lines. The effects are immediate and will last for several months. Some people who are severely affected with perioral lines opt to combine filler treatment with Botox for great, longer-lasting results.
