Contour correction is a unifying term for several entirely different skin treatments using dermal fillers, but usually conducted with the same purpose – to correct the shape of the body. Skin tightening, toning, face lifts, liposuction, certain botox injections, and several other plastic surgery and injection methods can fall under the category of contour correction, depending on the definition. The idea of body contour correction is quite an old one and has always been popular as a whole, however the favored techniques have changed over time. As with everything in the field of aesthetic medicine, the trend is to move away from the scalpel, and give preference to less invasive non-surgical methods, such as fillers. Modern fillers are capable of delivering results comparable to surgery with much less potential side effects and complications.
Scalpel and Injections
Initially injection-based methods of body contour correction used non-degradable synthetic dermal fillers, totally alien to our body. This was fine for a time, as it was the only viable non-surgical alternative. It was quite limited in the scope of its applications and side effects were still frequent. (In fact whether injecting non-degradable substances under your skin is safer than surgery from a biological perspective can be debated) Nonetheless, from the point of view of many patients, injection techniques appeared to be less threatening and when their popularity rose so did the research efforts. Eventually alternative organic injections were developed
Fillers with Hyaluronic acid, a substance naturally found in the human body are among the safest methods among the existing temporary fillers. Hyaluronic acid (HA) is one of the basic physiological components of the connective structure of the skin. It is responsible for the density of tissue, performs a vital function in stabilizing the three-dimensional organization of the components of the extracellular matrix and also has a natural ability to accumulate and hold water around itself, giving the skin elasticity, smoothness of texture, and a youthful look. As we age synthesis of HA slows down and the reserves of HA in the skin deteriorate. The quality of the intercellular substance of the dermis declines and as a result skin becomes less smooth, loses elasticity, accumulates wrinkles, and becomes drier.
Hyaluronic acid is rapidly synthesized and used up by our bodies, and each individual HA molecule has a very limited life span in a living organism - just a few days. Thus, any injection of additional Hyaluronic acid will be degraded quite quickly. To extend the aesthetic result, HA molecules need to be modified to become less recognizable for the group of enzymes called “hyaluronidase”, that degrade it. Chemical modifications prolong the life of the molecule from several days to several months. During all this time, HA performs its function of stimulating the formation of young loose connective tissue around the injection zone, until it eventually becomes degraded by the body.
Biological Rejuvenation of the Skin
Dermal fillers based on using Hyaluronic Acid have become quite popular, due to the enormous potential of the molecule. New applications for HA are being developed every year in this field and many others. Today's fillers can almost turn back time by eliminating wrinkles, restoring smooth lines of face and body, making lips expressive and appealing - all while maintaining a natural appearance, and without any surgical intervention. The key difference between today’s HA-based fillers and yesterday’s synthetic ones is that HA not only literally “fills” space under the skin, it prompts the body to make its own “filling” by stimulating the synthesis of extracellular matrix components.
Average duration of clinical effect after the introduction of biodegradable fillers is 8-12 months, meaning the processes the injection started continue for several months even after all the original injected material is completely gone! In our time, high-quality organic filler in the hands of a qualified specialist can indeed rival the results achieved by plastic surgery with none of the drawbacks.
