Correct gummy smile and deep horizontal crease above upper lip. Surgery or Botox? (photo)

Thank you for supplying photos, but unfortunately they are not at standardized angles for proper examination. Botox may be used for a Gummy Smile and can be used to soften the creases above the lip. These treatments relatively inexpensive as they do not require a large amount of units needed for Masseter or Forehead injections. 
If seeking potential treatment, I strongly recommend that you follow up with an experienced injector, preferably a Facial Plastics Surgeon.
Keep smiling!

Hi there! Thank you for your enquiry. Anti-wrinkle injections are very effective in general in the treatment of a ‘gummy smile’ and results usually last up to 4 months. This can vary however from person to person for reasons such as a difference in metabolism. It may be worth revisiting your practitioner for a review to discuss your concerns and re-evaluate your treatment plan before deciding to commit to surgery.
Hope this helps!
Best Wishes,
Dr Rupert

Botox or other neurotoxins can improve gummy smile.   Your injector May need to increase the dose to improve the results.
