Fillers or Dermabrasion for Lines Above Lips?

Upper lip wrinkle lines can be improved with fillers such as Juvederm and Restylane. The correction should last about 9 to 12 months. Usually it is advantageous to add filler to the borders of the lips as this helps efface the lines in these areas and can also provide fullness for the lips.
Adding Botox will diminish the active wrinkling caused by the movement of your lip muscle and can enhance the result though not everyone likes the "feel" of Botox in the lips, and the Botox only lasts about 3 to 4 months. Dermabrasion can significantly reduce wrinkle lines and provides a more permanent correction.
Adding fat grafting improves the result, and can provide fullness for the lips if desired. Some doctors feel that the stem cells in fat grafting will help "restore" the tissues to which the fat is added. The results of fillers are immediate and there is minimal downtime. Botox takes 2 days to 2 weeks to be effective. Dermabrasion is a surgical procedure and has significant downtime of 7 to 14 days. Fat grafting looks overdone for about 2 weeks. Many times, dermabrasion and fat grafting is done at the same time other facial rejuvenation procedures are being performed such as face and neck lift.

Easy answer is use very temporary fillers (Restylane, Juvederm) first. There are simple to inject, last 3 months, are inexpensive. If after a trail with the temporary fillers you can proceed to a semi lasting filler (Perlane, ArteFill). Dermabrasion is a surgery that has healing time of 2 weeks to months, and is much more expensive.
The basic physiology of upper lip wrinkling:
1. Loss of volume in dermis or a thinning of the tissue causing a valley/crater appearance;
2. muscle hyperactivity;
3. a combination.
So the treatment is either fill the valley with a filler or fat vs sanding down the hills of skin on each side of the valley (vertical lines) in the lip. Hope this helps.
