1. The very first thing they educate you on through medical school regarding how to analyze scientific studies are what individuals obtained the actual research. In this instance the sponsor for this research and paper was Erchonia the business that produces Zerona lasers.

2. Exactly who submitted this article? In this instance this article seems to happen to have been authored by Ryan Maloney. Who’s Ryan Maloney? He is not  only the medical director of Erchonia he actually is one of the owners of the patent on the Zerona laser. Aside from that you don’t know his experience. We know he’s not even a PhD or MD. Usually it might be right behind his name under the authorship of this article. He  shows a special economic gain to publish this article in a beneficial light.

3. Eight individuals did not have finalized measurements. The 1st dilemma is why? Four had been from the treated group and four were in the  placebo group. At first that seems to be OK, but if you examine further within it, they retained all of those test subjects within the study.  They took the last measurements for those patients and brought them forward. Yet again, it looks Ok to start with but at the time you  start to look at the pattern of circumferential reduction in the 14 days post treatment the sizes are trending back toward  baseline. So if you ever include these patient’s final measurement (which by the way is the very best overall average circumferential reduction  during the procedures for the treated group) and take them forward they’re going to artificially reduce the real values fourteen days post  treatment. All eight of those subjects should’ve been removed from the study.

4. There isn’t any examination of aesthetic benefit. To have this be worth something you would have to have before and after pics which  are assessed by several people that are blinded to which treatment the particular participant received. So, in other words,  is a 3 inch reduction visually significant.

5. They just do not say if patients are male or female. So the question is left, can it work as well on males as it may on females? This is extremely important because men tend to have thicker skin. As a result, will the laser penetrate as deep in men?

6. the study was limited to patients with a BMI of 25 to 30. Now I think it is fine to have this limitation as you’ve to  start your research somewhere. But the limitation is that the article is implying that it will work for all BMI’s. What about the  thinner female patient with a BMI of 20 but has a small lower abdominal pooch? Or what about the patient that has a BMI of 35?  This should be stated in the conclusion but Mr. Maloney seems to forget this.

7. They also do not state if the patients received their treatments for free or if they were compensated for their time. This  is only important for the portion of the study that talked about the patient satisfaction. We need to understand that patients  will put a value on the procedure because if something is free their expectations are much lower. their expectations are much  higher if they paid $2500 for the procedure. So if this was free to the patient and you have 30% of the treated group that are  dissatisfied or neutral what would that mean to a clinic if the patients are paying for it. I would guess you will have a much  higher dissatisfied group that either wants their money back or free procedures. I do not want something in my clinic that has a  30% failure rate.

8. They do not discuss if either group was asked to change their diets. This should be stated up front in the methods portion  of the article. They also do not mention if there were any dietary supplements required such as niacin. Almost all clinics using Zerona  are having the patients take niacin even Erchonia recommends it.

9. They set the standard for success to be an inch loss of 3 inches or greater. Only 62.86% of the treated group achieved  success. So this translates in to a 37.14% failure rate. Again, not something that I would want to stake my reputation on.

10. Now what do the numbers mean? In the event you look at the numbers the patients baseline combined measurement average was 120.31  inches. At week 2 of treatment (the best measurements achieved) the average was 116.79 inches or an inch loss of 3.52 inches on  average. This sounds pretty good until you look at the true numbers. Using the numbers from the study this equates to a 2.9% inch  loss as measured over 4 areas. Is this clinically (visually) significant? I do not think that many individuals will be able to see  a 2.9% change or if they can it will be meaningful.

11. Lets take a look at the 2 weeks post procedure measurements. Remember, these are not true numbers as 4 patients had their  best numbers included in these measurements pulled forward and included here. (I think all of their measurements should have been  puled out). At 2 weeks post treatment, you see a .31 inch increase from the circumferential measurements at the 2 week  treatments. What this equates to is an 8.8% increase in inches in only 2 weeks. So what takes place at 4 weeks? 6 Weeks? So if it were  a perfectly linear increase it would only take about 20 weeks or so to be 100% back at baseline. That is if it were linear and I  highly doubt it may be a linear response and if i had to guess many patients will be back at baseline measurements within 6 to 10  weeks and this is why there are no long term scientific studies. The organization has had ample time to produce longer term reviews they  apparently do not want to.

So as you can see, there are a few issues with this article and how it was analyzed and written. The first and foremost problem is  that the article was authored by an individual with direct financial interest in the product. The ASLMS journal never should have  published this article on account of the authors conflict of interest or it should have a disclaimer prior to the abstract. I have no  vested interest in any of these non-invasive technologies and would love to see something like this work and have long term  benefits for the patients. I think this technology may have better long term benefits on cholesterol etc. I have heard that there  are some interesting research coming. I just hope they are not written by Mr. Maloney. And for others reading this I assume that  Chad works for Erchonia or the marketing and advertising company that is selling this thing to anyone they can including chiropractors.

This skin tightening procedure functions through tightening the existing collagen as well as stimulating brand new collagen growth, which means improvements aren’t only instantly obvious but may continue for around 6 months. The treatment is ordinarily done in a single session that requires between 20 minutes and two hours depending on the area that is to be treated. Recovery is fast, and pain free.

Is Thermage something I want?

As we age our skin loses natural moisture and elasticity when our collagen molecules breakdown resulting in a wrinkled, lined and dry skin texture.

Thermage Epidermis Tightening Procedure is suitable for most skin types and colourings. The procedure will refresh skin through working for the existing collagen which makes it tighter and stimulating new growth. The result can be smoother tighter epidermis which will appear younger and less wrinkled or lax.

Ladies between the ages of 35-60 typically possess the right and most predictable final results, although a consultation might be able to determine predicted individual outcomes.

How Thermage works:

Facial skin is comprised of Three layers – The outer layer (the epidermis), a collagen- rich underlayer (the dermis) and an inner layer underneath the dermis (the subcutaneous layer – also known as the fat layer) which has a web of collagen fibres running via it.

Thermage skin tightening procedure may be the only non invasive treatment available which tightens and renews your skin’s collagen in all 3 tiers. By applying unique Capacitive Radiofrequency (CRF) technology which safely heats your skin’s collagen, your skin will instantly tighten and turn out to be smoother in consistency and tone. New collagen progress will mean that the outcomes will continue to appear over time.

Normally, the complete procedure will take from 20 minutes to two hours, depending on the procedure location. General anesthesia is not needed, but to ensure you are comfortable the MD might offer light discomfort medications before procedure.

What does the Thermage procedure feel like?

As the CRF power is delivered to the dermis and underlying tissue a brief deep heating sensation will be experienced. This deep heating sensation can be an indication that collagen is reaching successful temperatures for tightening.

The surface with the skin is chilled before, throughout, and after each application of CRF energy, this will safeguard the skin and make the treatment much more comfortable.

After your Thermage treatment

After the Thermage Skin Tightening Procedure, the skin may be slightly red or swollen for the day or two. But most citizens resume regular activities immediately after treatment, and unlike surgery there’s no downtime or special follow-up care.

Following the procedure, you should continue to see improvements to your skin as a result from the production of new and increased collagen, as well as some additional contouring effects due to continued tightening over time. These effects will continue for up to six months.

How much does Thermage cost at a local medical spa

The price of this particular treatment is influenced by for the size of areas needing cure. Following an initial appointment, you will be advised of the price.
