After the anti wrinkle injections wear off, usually in 3 to 6 months, the muscles do recover.
However, because the muscles have not been active for a long time, they usually do not recover to the same intensity as before you had the
anti wrinkle injections.
This means that the facial muscles do still function, so you have normal expression but not with the intensity in the brow area that gives you the frowning and angry, unapproachable appearance that the scowling heavy muscles deliver to those with whom you are talking or communicating with.
