There are two components to these lines. One is the muscles that create the frown expression AND the other is the crease created by the frowning.
To deactivate the frowning muscles we use Botox to paralyse them. It is not a painful treatment but only lasts about 4-6 months. To treat the crease we use filling material such as Restylane OR Evolence.
Each case is individualized as often just the Botox does the trick AND and in another person just filling is needed. Examination by a qualified plastic surgeon can help to determine the best approach.
