This is an excellent question. Stretch marks can be improved with the laser. This is a matter of rebuilding the collagen in the dermis which is lost due to the striae. I would normally recommend doing the laser both before and after and is you will find that several treatments may be necessary in order to achieve the best result. The issue then becomes timing which you should discuss with her plastic surgeon.
Laser treatment to improve texture and stretch marks is now doable when combined with a neck lift or facelift. We have extensive experience in combination therapy an found improved results when performed together.
