Fraxel Laser Increased Collagen in the Lips?

Hi Niy,
You have not told us how long ago the Fraxel re:store treatment was, or when your fat transfer was.
The swelling will go down with time. 
I hope that your lips return to normal quickly.

The Fraxel Restore does not go deep enough to increase lip size through new collagen production. Your lip swelling is simply inflammation from the treatment and will go down eventually.
You may also have an allergy to the cream or ointment you are using-this is a much more common cause of lip swelling after laser treatments in the lip or peri oral area.
Fraxel does not go deep enough to effect the fat that has been transferred to your lips. If the fat transfer was done at the same time as the Fraxel, it is also contributing to the prolonged swelling-lip swelling after fat transfer can take 3-4 months to resolve

The lips swell a lot when the are exposed to laser and other resurfacing treatments.  I don't know how far out from surgery you are, but your swelling should go down within days of the procedure.  You may also ask for oral steroids (medrol) to expedite.
