While it is true that heat results in skin tightening - just as when you cook food, the protein congeals and shrinks, there are, in my opinion, much better ways to do this than with a laser. It is the dermis and the subcutaneous tissue fascial framework that needs to be heated to cause skin contraction. If you apply a laser to the skin, then you must burn through the epidermis and heat the dermis. This will not reach the underlying fascial framework. So yes, a laser can give you skin tightening, but not the best result nor the most efficient with the least downtime.Over the last few years, the trend is towards applying radiofrequency energy to tighten the skin. While early attempts to do this to the surface of the skin (ie Thermage) have failed miserably, the proponents of this technology were in the right ballpark.For a while, I used ThermiTight to tighten the skin and it really does work. A long probe is inserted under the skin, an electrode at the tip is energized and the underside of the skin heats up, causing dermal and subcutaneous tissue tightening. I have seen some very impressive results with it.However, as technology improves, other devices emerge. The best one, in my opinion, is BodyTite. This operates under the same premise as ThermiTight, however, there are some technical differences. Suffice it to say that the energy is delivered at a higher power with BodyTite and it is bipolar as opposed to the unipolar ThermiTight, making it more "efficient" in its task. The last thing about BodyTite that I really like is that there is better thermal protection to prevent skin burns, than when using ThermiTight (although burns have not been a problem for me with this technology).I see that you live in Boca Raton. My colleague Jason Pozner is extremely experienced with this technology and I recommend that you see him. He taught me to use this technology and I am very happy with it. Good luck.
