The Pros and Cons of Muscle Relaxants

The easiest way to distinguish muscel relaxants form dermal fillers is by remembering that muscle relaxants work on ‘moving’ lines that appear with facial expressions, while dermal fillers address ‘static lines’ that remain even when our faces are resting.

What are muscle relaxants?

Botulinum A muscle relaxants reduce or stop muscle contraction that occurs with facial expression such as lines on your forehead when you raise your eyebrows, crows’ feet when you smile, or frown lines.
Due to medical advertising laws, I can’t mention Botulinum A products by their common brand names, but it’s highly likely you’re familiar with at least one well-known brand.

What can muscle relaxants be used for?

Botulinum A muscle relaxants can be used to reduce or eliminate the wrinkles and lines that appear as your face naturally moves. Common treatment areas include:

  • The frowning area
    Lines that appear across the forehead when you raise or lower your eyebrows
  • Crows’ feet
    The creases that appear around the eyes when you smile
  • Bunny lines on the nose
    These often appear when smiling
  • Down turning of the corners mouth
    These occur naturally as you age.
  • Strap muscles in the neck
    These can be very marked in certain facial expressions with some women.

What can’t muscle relaxants be used for?

Botulinum A will not work on lines that you see when the face is at rest.

For example, if you have deep lines in the frown area, these will not disappear with a muscle relaxant, although the muscle relaxant will prevent the deepening of those lines when you try to frown.

Do muscle relaxants work straight away?

No. You will not see any visible difference immediately after your Botulinum A injection. It typically takes one to four days to notice any difference in the strength of your muscles; and up to two weeks for the full effect to be seen.  This gradual effect means the people around you, even your partner, will not tend to notice that you’ve “had work done”.

How long do muscle relaxants last?

Typically, the effects of muscle relaxants last for around three months.

Some lucky people will get six to eight months from a single treatment; and on a rare occasion someone may find the effects wear off in six to eight weeks, especially if they have a high metabolism or lead a highly active lifestyle.

What side effects can occur with muscle relaxants?

It is possible to bruise around the treatment area following Botulinum A.
