Is Botox or Dysport Used for Feather Wrinkles on the Lips?

A small amount of Botulinum Toxin may minimize the vertical wrinkles of the upper lip. It is not recommended for musicians that play wind instruments or professional singers as there might be difficulty pronouncing certain letters initially. For those people whose muscle creates significant pursing of the lips, the deep vertical lines can improve significantly with the Botox or Dysport and filler can be used in addition.

The fine vertical lines on the lips respond to a combination of the fillers like Restylane or Juvederm and a very small dose of Botox or Dysport in the wrinkles. The dosage has to be very small and carefully calculated or it can lead to change in the lip shape with an abnormal appearance, and sometimes changes in speech and swallowing.

Although I hear often about this being done, I do not personally recommend or perform botox injections to the lips themselves. As noted by the other physicians, this can produce problems with speech articulation and facial symmetry.
I find that mild lines are well treated with volume fillers. I personally like Juvederm due to the softness of the product in the lip.
For deeper lines, dermabrasion/laser/chemical peel technqies produce excellent correction
