In order to treat crows feet, Botox and Dysport can certainly help relax the orbicularis oculi muscles which contribute to these wrinkles. The drug of either product works by blocking the release of a neurotransmitter called acetylcholine from the nerves that communicate with these muscles.
Basically, Botox and Dysport can be used for facial expression wrinkles that are located at eye level (in your case- crows feet) or above. So these would include forehead lines and frown lines, also referred to as the elevens. Injections can also be applied to lift the eyebrows. In some people, age causes the muscles in the forehead to atrophy. And their brows will descend as a result. Muscles work in opposite pairs. So relaxing one set will automatically make the other contract. And this strategy can be used to lift the brows.
Generally, these injectables should not be used in the lower part of the face around the mouth. This can impair speech and the ability to eat. However, there may be some exceptions.
Besides the type of wrinkle, candidates would need to be in general good health. Botox and Dysport are contraindicated for anyone with conditions that weaken the muscles. They are also not to be used for those who need to be on certain types of medications. And they are prohibited in women who are pregnant or lactating.
These are just general guidelines. They are not intended to serve as specific medical advice. Therefore, it would be best to speak to a board certified dermatologist or plastic surgeon
