Do you recommend Power Star Body Sculpture machine to loose some fat at my tummy? And does it tightens my skin?

Anything that claims it will tighten skin tends to be very disappointing in my experience. I would recommend Coolsculpting for fat removal without surgery and hope your natural skin elasticity will tighten enough like with weight loss. If you have excess skin after this can be removed with a tummy tuck or body lift but you should see a degree of skin tightening naturally. Be vary cautious with all these new noninvasive fat loss devices as most don't work!

It sounds like this device is trying to use all the buzzwords of noninvasive fat reduction but it does not appear to be FDA approved for fat reduction. HIFU is a proven technology with Liposonix and Ultrashape, but not all HIFU is the same so just saying it has that doesn't mean it is actually doing anything. Cavitation is an effect of ultrasound that can occur under certain conditions but again it is meaningless to describe it as a technique or a technology. Go with proven technologies but even those have limitations. If you have had 2 pregnancies and a C-section it is likely that a tummy tuck should be considered.

No - I can not recommend the PowerStar Body sculpture machine.  I did look at the YouTube video the company has posted.It does not appear to have passed FDA testing for safety.  The effect of this machine is unknown at this time.I'd stick to technologies that have been FDA cleared - like CoolSculpting.  

There will always be devices claiming to be the latest and greatest, and of course these devices claim they can provide a desired result without surgery. Find a plastic surgeon you trust and follow his instructions. 

No, I would not recommend this non-FDA approved treatment.There is no photos and your questions implies that there is skin laxity.  If you have laxity, not of the noninvasives with come close to a short scar tummy tuck.

There is a lack of valid scientific data about the claims from Power Star Body Sculpture. Radiofrequency treatments from Vanquish or fat freezing from CoolSculpting are more proven for nonsurgical fat removal. While there may be benefit in the appropriate patient for non-surgical fat contouring,there is no non-surgical device that will produce the same result as artistically performed liposuction.I would suggest that you find a surgeon
certified by the American Board of American Plastic Surgery and one who is
ideally a member of The American Society for Aesthetic Plastic Surgery (ASAPS)
that you trust and are comfortable with. You should discuss your concerns with that
surgeon in person.

Things of that nature tend to be extremely disappointing to most patients in my experience. I see a steadty stream of patients that try various machines and feel they have not gotten their money's worth.
