How Much Does Mesotherapy Cost?

As a Board Certified Plastic Surgeon, I must say that our society as a whole does not endorse this therapy and there are no current FDA regulations regarding the chemicals utilized in Mesotherapy.
I would urge great caution and only proceed if you have a trusted friend or family member who has undergone the treatment with satisfactory results.
Because I currently don't perform the procedure, I cannot give you advice on the costs.
However, I have seen several, treatment "failures" from practitioners in the area.

I do not recommend it and I warn against it. Patients that I have seen after the therapy have all been unhappy with the results. Also, we just dont know where the fat goes; being absorbed by your body is not physiologically sound.
Just dont do it. If you're interested in getting rid of the trouble areas, do what is proven to be effective and has a higher saftety index—liposuction.
Hope that helps.

A major advantage to this treatment over many others is how reasonably priced it is. While there is no one clear-cut answer to how much Mesotherapy can cost, you can expect each session to be priced from $250 to $600, at least the procedure to improve skin texture, though this may greatly vary depending on where you live.

This really depends upon the volume required, we charge £349 per ml of Juvederm volift mesotherapy. There are cheaper alternatives but the products in the EU are produced by companies with no established history or verification of manufacturing process. 

Despite popular belief, mesotherapy is not the same as fat - dissolving injections. 

Mesotherapy is a technique of injection of medication, or another substance under the skin.  The idea is that the medications are absorbed via subdermal plexus and produce specific result, like reduction of inflammation, not necessarily related to cosmetic surgery at all.

The original idea was that anti-inflammatory medications can help with improvement of arthritis symptoms, chronic inflammation and so on.  The medications used for that are toradol, papaverin, lidocaine, procaine and so on.

Another technique commonly mistaken with mesotherapy is also known as needling or "nappage", when vitamins, bioactive elements, hormones and other substances are places on the surface of the skin and then a rol with needles is applied to the skin to stimulate skin rejuvenation.  Estheticians commonly use this method.

In US mesotherapy is most commonly referred to as "fat melting injection" and they created quite a bit of negative publicity because of some advertizing issues, complications, overpromising and many other issues.

Overall, before considering mesotherapy know exactly what is going to be done, what medications are to be used, what results can be expected, and consult your plastic surgeon first.  In US at this time this is not recognized as a valid treatment modality.
