My doctor has suggested 6 treatments of fractora laser will this give me the results? (photo)

There are a lot of treatments available to help tighten and improve the quality of the skin on the neck. Fractora is an excellent option. It is actually not a laser, but works using radiofrequency delivered into the skin through very fine needles. Fraxel laser on the other hand is delivered from the skin down. 
Regarding Fractora - 6 treatments is quite a lot. I would start with a combination treatment using Fractora and Forma to tighten and improve the skin. This is a really good option.
I offer a number of different options too. RRS by SkinTech, intradermal injections are really good at tightening and reducing the sagging in the neck area. Profhilo also helps to improve the neck area and used with a 10 point lift can give some great results.
Several options to think about. But make sure you have a really good neck cream, Ultra Firming Neck Cream by NeoStrata and Body emulsion by ZO Skin Health area all good.

Please remember the Fractora isn't a laser, be wary of practitioners calling it such.  It uses radio frequency technology in conjugation with mico-needling to deliver heat deep into the skin. This causes a remolding of the skin and a tightening of it as well. Fractora works from under the skin allowing collegian  to remodel. So in several weeks you will have much healthier skin, but keep in mind a series of three treatments is recommended for optimal results.  In our experience it causes for a tightening of the skin and visibly improved skin from sun damage.  It works well for a maintenance option for post surgical to help extend your results.
