Are at-home 3MHZ ultherapy machines that penetrate to 4.5 cm effective?

Even though it may sound and read  like a great deal, I do not think it is in your best interest or safe to purchase a machine and perform treatments on yourself.  The best and safest option is to have the procedure performed by a board certified facial plastic surgeon or dermatologist who has the authentic Ultherapy machine.The technology behind Ultherapy is very sophisticated.  The machine delivers a precise amount of ultrasonic energy to precise tissue depths, that causes a very specific temperature level at that depth.  And only at these precise depths and precise temperature levels can you get the results that Ultherapy delivers.The attached link provides more information on Ultherapy.I hope this helps.  

I suggest going to a board certified dermatologist or plastic surgeon who specializes in these treatments as serious complications can occur with non certified and at home treatments and machines.  Best, Dr. Emer.
