My philtrum looks saggy when I smile, what can I do to fix it? (Photos)

You appear to be an excellent candidate for a lip lift.  A lip lift does 4 things: shortens the distance between your nose and upper lip, increases the mucosa of the upper lip, increases the incisor show and pulls up the corners.Best Wishes,Gary Horndeski, M.D.

There are surgical and non-surgical approaches to lip augmentation. Non-surgical approaches include botox (slight lift, reducing gum show) and filler (volume restoration). Surgically, you can have two separate incisions under the nose (italian), one incision under the nose (bull horn), one incision at the red/white upper lip junction (gull wing) or two separate incision at the corners, or a combination, depending on your desired look and anatomy. My preferred surgical technique is called the Elelyft, which is a version of the bullhorn approach.
You seem like an appropriate surgical candidate based on your photos. An in-office consultation or video consultation would be key to confirming that. 
Consult with an experienced lip surgeon for a complete range of options that are appropriate for your situation.

Hi there and thank you for your question. We divide the upper lip into two parts, the red lip part is called the labial lip and the skin between your red upper lips (labial part) and your nose is called the philtre part of your upper lip. According to your photos your philtrail upper lip is elongated with a shortened labial part. Performing an upper lip lift will certainly improve the proportions of your lips. It is important to keep in mind, that this procedure is performed with less elevation in men, to make sure your upper lips will not look like the upper lips of a woman. Try to  find a plastic surgeon who is well experienced with lip surgery in order to have an in-person consultation. Good luck!

Kind regards,
