Will my upper lip rise or fall as I hear conflicting information? (Photos)

Postoperatively, after a lip lift, you can anticipate bruising and swelling that will be noticeable to you and others for about 1 week. After the sutures are removed or dissolve, depending on the type used, there will be redness along the incision line for 4-6 weeks but this can be covered with makeup. Sometimes the upper lip lift is overcorrected with the initial procedure and will slowly assume its final position over weeks to months.
I can tell you that 3 days out is far too soon to jump to conclusions. That being said, 3mm is a very little amount to remove. I have never removed less that 4mm, since you need to create enough of a difference to justify the procedure and the risk of scarring. The cut into the nostrils is one technique and should have been discussed with you in detail prior to the procedure. Talk to your surgeon about the anticipated recovery process. The suturing does look meticulous. Best of luck.

3 days post op is too soon to judge your result.  Everything looks good in the photo.  Discuss your progress with your surgeon.  Hopefully, when everything settles you will be happy with your result.
