Summary: Cosmetic surgeons are always looking for a way to improve their practices. One way to do that is to catalogue the ways in which hyaluronic-acid based dermal fillers are different from one another. After all, there are plenty of different fillers on the market, so it can be difficult to keep track of which filler works best in which circumstance. However, researchers have developed a way to do just that, based on the cohesivity—the ability of molecules to stick together—after injection. This can help surgeons determine the best injectable for your desired results.

Finding the Best Injectable for Your Desired Results

There are many characteristics that make for a good dermal filler injectable. Many of those characteristics will, of course, depend on the desired results. There are some results that will be best produced by Juvederm and others that will be best produced by Restylane Silk. But that isn’t to say that plastic and cosmetic surgeons are not looking for some overall qualities that tend to make a good dermal filler. It should be noted that Botox cosmetic injections are not covered under “dermal filler” discussions, as Botox is not itself a dermal filler (it mitigates wrinkles based on a completely separate operating principle).

What qualities do surgeons look for in a dermal filler? Well, one big one is something called cohesivity. When testing for cohesivity, researchers were looking to see how well the dermal fillers were sticking together. It should also be noted that this metric only worked when applied to hyaluronic acid-based fillers (this includes fillers such as Juvederm and Restylane, but not fillers such as Bellafill). Hyaluronic acid-based fillers already have a widely respected reputation when it comes to what they can accomplish for patients, but the excess of formulations and permutations pumped out by manufacturers can make it difficult for surgeons to choose the best injectable for a particular situation.

Using Cohesivity as a Reliable Metric

Having this metric—cohesivity—can help surgeons figure out what they should use and when. Essentially, by measuring how well the molecules of a hyaluronic-based dermal filler can stick together, surgeons can better anticipate the look and the feel of final results using that dermal filler. The researchers who developed this testing methods tested six different FDA approved hyaluronic-based dermal fillers, and the results ranged from full cohesivity to full dispersion. In other words, in some dermal fillers, all of the molecules stuck together really well. And in other dermal fillers, the molecules tended to disperse and spread out.

At first glance, this might seem as though some dermal fillers are “better” than others, but that’s actually not the case, nor is this method designed to bear that out. After all, there are many situations where you might actually want the dermal filler to spread out. For instance, there are some cases where if a dermal filler is too thick, it will block the translucence of the skin, causing the skin to look plastic and artificial. On the other hand, there are times where you want to have very precise control of where the dermal filler is administered.

A Boom in Non Surgical Procedures

This is even more important given just how many procedures dermal fillers are used for. For example, if you were to get a revision rhinoplasty in Los Angeles at Westside Aesthetics, you would probably want to use a dermal filler with high cohesivity. There are currently many of these procedures available—patients can get a non-surgical solution to a traditionally surgical procedure. In many ways, these procedures are exceptionally wonderful because they allow patients who might otherwise avoid surgery to get excellent results. But it does make the selection of a dermal filler much more important.

It also makes it more tempting than every for manufacturers to create new and diverse products. Restylane Silk, for example, is specifically formulated for patients who want a non surgical lip augmentation procedure done. The smaller particles make the lips look much more natural than they would with other dermal fillers, which may cause a “grainy” look. It’s would not be surprising, then, that companies will be looking for a way to create new products that make results of non surgical procedures better. These better results will certainly benefit patients, as well as surgeons who will have more control over the procedure. But it will also complicate the choices involved.

Get Results That Are Great For You

Plastic and cosmetic surgeons, therefore, need a way to have confidence in the dermal filler they select. Currently, much of this confidence comes from experience and intuition. But the research recently performed by Dr. Hema Sundaram and Dr. Samuel Gavard Molliard will help cosmetic surgeons make decision based on empirical data. If nothing else, that will help to reassure patients of the results of these decisions. That said, even without this, cosmetic surgeons generally get excellent results. After all, it takes a significant amount of training and expertise to begin giving patients injections.

So if you want to diminish wrinkles or you want to alter your appearance, dermal fillers are a great option for you. Fortunately, there are enough options that one dermal filler or another can accommodate your desired results.
