Is there anything that can be done to improve the look of my lip lift scar? (Photos)

Thank you for your pictures your healing looks good.  Please do follow your surgeons protocol.  You could at this stage application moisturise or bio oil to help hydrate the scar.  All The Best 

There are several options for lip lift scar, including:
Surgical revisionLaser resurfacingDermabrasion
A surgical revision is often favored, assuming there is still room along the philtrum to remove more tissue. Since less tissue is removed during a revision compared to the original lip lift surgery in most cases, the area is under less tension which usually results in better healing and improved scar appearance. The redness will always improve with time. Gary Linkov, MD

Revision bullhorn lip lift. This is why I never use this! For 45 years I have used the M type lip lift which has the scar INSIDE the nose except for a small one at the base of the columella. I have never had to revise my lip lifts. See a very experienced lip lift surgeon to excise this scar and convert it to a M type  

Talk with your surgeon. Are they prepared to help you with the scar or are they simply being unhelpful? If they are unhelpful, I recommend seeking out a dermatologist who is offering scar care. This is becoming an increasing focus for dermatologist. The redness can be improved with laser treatments. Also the volume of the scar can be helped with 5-FU. You do not have to live with this.
