Does Beautytek work to lift and firm breasts? What about effectiveness on stretch marks?

I would be highly skeptical of this product.  Breast firmness is determined by the amount and quality of breast tissue related to fat content of the breast.  A "lift" requires removal of excess skin.

Be careful. If a product or procedure sounds too good to be true, chances are it won't work, because every doctor would have one! Just like fat busting pills that claim to dissolve fat without exercise, many of these devices are unproven. Check out the link below to an article I wrote about sham procedures. Remember, buyer beware!

While there are all kinds of different treatment machines available abroad which claim to firm and tighten, FDA approval is usually much more stringent and usually has to show some sort of efficacy.  While this machine is available in a few markets in the US, it is not widely prevalent because often times these sort of devices do not offer long-term results but rather a temporary improvement only.  In most of the before and after pics, it is clear that while there may be some improvement, surgical intervention could have given a much more profound improvement which is permanent.  So be wary of the cost versus benefit when considering a device such as this.  Further, make sure you understand the training of the provider or supervising provider of the person doing the treatment.  Best of luck!

Load of crap.You thought it was too good to be true and you are right! Stay away from those magical creams and machines. All they do is lighten your wallet.

Please save your money. These devices are pure gimmickry and prey on patients who want gain without pain. Also keep in mind that Photoshop is a wonderful thing; if it can be used to airbrush out cellulite, it can so all sorts of things!

Generally non- invasive devices that show results that are too good to be true are. Be very skeptical of new gimmicks and devices that show incredible results. Find a board certified plastic surgeon in your area and discuss which options are best for you. Good Luck!
