Restylane is the first hyaluronic acid dermal injection approved by the FDA (2003). It is used to fill in facial hollows, add volume to the skin and smooth wrinkles.
Restylane’s active ingredient is hyaluronic acid. According to the Plastic Surgery Guide, this is a natural sugar compound that is found in our bodies. For example, it is a component of connective tissue and functions as a lubricant to protect cells.
The molecular structure of hyaluronic acid allows it to bind to water molecules up to 1000 times its own weight, making it excellent for hydrating and adding volume to the skin. It also binds readily with the existing collagen and elastin. It even promotes the synthesis of new collagen structures.
Restylane also consists of a patented form of hyaluronic acid called NASHA. This stands for non animal stabilized hyaluronic acid. This secondary ingredient forms the base of the gel-medium that comprises the injection.
One of Restylane’s advantages is that it presents a very low risk of prompting allergic reactions. This is because it is protein free. Instead of protein, bacterial derivatives are incorporated into the final formulation of the product.
Since it is non-animal sourced, the organic ingredients are the result of bioengineering.
The nature of hyaluronic acid makes it an ideal dermal filler for correcting areas such as:
Additionally, there are different treatment techniques that can be applied. These depend on the procedure’s objective and producing outcomes that that are natural looking and aesthetically balanced.
Juvederm is a similar product that is also made of hyaluronic acid. Restylane’s consistency, however, is firmer than Juvederm. Decisions on how and when they are used really depend on the unique characteristics of the issue that is being addressed. For example, Juvederm would not be ideal for chin contouring. In some instances, Restylane can even be used on the nose.
The number of injections will vary with each condition. This can be determined prior to the actual procedure.
Restylane injections will last approximately 3 to 9 months. This depends on several factors, including how much is injected and the metabolism of the patient.
Restylane not only adds volume to the face, it adds structural support as well. A specialized physician will be able to evaluate factors with individual patients such as smile patterns and overall facial anatomy to administer it in a way that gives the best results.
