I had an endonasal lip lift yesterday.
Very happy with the results, even after one day. Surgeon used transparent sutures, so it's barely visible. Have a tiny line next to each nostril. The incision under my nostrils are hidden inside my nose. The sutures are extremely small. He spent about 45 minutes on the sutures alone.
If you want minimal scarring, check out "endonasal lip lift" it's relatively new, and quickly becoming the next best thing.
