Getting to Know The 4 Main Types of Injectable Hyaluronic Acid

Dermal fillers are a very much in demand with hyaluronic acid, a temporary filler, being the choice of many clients and patients just simply because the results are not permanent or toxic to the body.

Hyaluronic acid is one of those structures that is uniform throughout nature and very well tolerated by almost everyone. The hyaluronic acid that is injected for cosmetic purpose is stabilized into a viscous gel by a cross linking process.  It is soft enough to move with the face without being animated and stable enough not to be absorbed by the body.

There are four main hyaluronic acid preparations that are in use today. These are

Restylane – This is an FDA approved substance produced from the cultures of Streptococcus equi.  It is very biocompatibile with the native hyaluronic acid in your patient’s skin, which means that the results are likely to last a long time. There are many types of Restylane that are not yet FDA approved on the market including Restylane Fine Lines (for superficial lines) and Reystylaine Perlaine (for volume contouring). The viscosity of Restylane is directly proportionate to the size of the particles in the gel.

Hylaform (INAMED AESTHETICS) is an FDA approved hyaluronic acid made from rooster combs that is crossed with divinyl sulfone. It is slightly less biocompatible with the dermis. Its very large particle size makes it better for deep dermal implantation.

Captique (INAMED AESTHETICS) is a synthetic, non-animal hyaluronic acid dermal filler that is produced through the process of bacterial fermentation. This suits clients who do not like the idea of avian proteins in their body.

Juvederm (INAMED AESTHETICS) includes a line of hyaluronic acid fillers that boasts increased biocompatibility because the particles have been reduced to a homeogenous gel. It also allows for refined results and techniques.

Each of these is injected intradermally, which is an art that takes great skill. If the substance is injected too deep then the duration of the effect will be shorter, maybe even a matter of days rather than months.  If the substance is injected too shallowly into the skin then there maybe bumps, skin discolorations or areas where an excess fullness is very obvious.

One of the benefits of injecting hyaluronic as compared to other types of injections is that it does not usually require local anaesthesia to be administered.
However, one of the axioms of this type of injection is that it seems the deeper they are more likely the patient is to be in discomfort as you inject them.  If you are less than artful with the needle as you are administering the injection, you can cause bruising.  Excess bruising decreases the effectiveness and the duration of dermal filler as its life can be shortened because of an extreme inflammatory response.  The average life-time of a hyaluronic filler is about nine months.

It is how talented that you can become using a needle that has to do a lot with how well your patients will do afterwards and also how long the effect will last.
