Hyaluronic Acid Facial Fillers
Hyaluronic acid is a naturally occuring substance in the body which can be made in the laboratory and used for facial augmentation. This article shows information about several hyaluronic acid substances on the market today.
Facial fillers is a broad term which refers to temporary or possibly permanent injectable materials which are added to the face to erase some of the signs of aging. There are many on the market today and this article will focus on several on the market composed of hyaluronic acid.
Restylane, Perlane, and Juvéderm are composed of hyaluronic acid. Hyaluronic acid is a component of all connective tissues, especially abundant in the deep layers of skin, and is the same chemical composition across species. Three different formulations of Juvederm were approved by the FDA in 2006 for injection into the mid to deep dermis for correction of moderate to severe facial wrinkles and folds (such as nasolabial folds). The formulations differed in the size of the hyaluronic acid particle. Adverse side effects of Juvéderm treatment are rare, and usually go away in less than a week without any intervention. Side effects of Juvéderm usually result from the injection itself and may include redness, tenderness, swelling, firmness, and bruising. Since your body already contains hyaluronic acid, and the ingredient in Juvéderm is created through biosynthesis in a laboratory and is designed for biocompatibility, there is very little risk of an allergic reaction after Juvéderm treatment. Juvederm is estimated to last approximately 6 months though individual results may vary.
Restylane is another hyaluronic acid, similar to Juvederm. It is also synthetically created and technically has less hyaluronic acid per volume, though the significance of this clinically has not been determined. In theory it lasts less time than Juvéderm though the actual results in clinical practice have yet to be directly tested. Restylane too is said to last about 6 months though individual results may vary.
Perlane is another hyaluronic acid which is synthetically created from Streptococcus species of bacteria. The final product does not contain any bacteria but can cause allergic reaction is there is any previous history of problems with similar substances. The particle size is slightly greater than Restylane which makes it a better choice for larger grooves. It is indicated for implantation into the deep dermis to superficial subcutis for the correction of moderate to severe facial folds and wrinkles, such as nasolabial folds. Like Restylane, Perlane lasts about 6 months and does not generally cause allergic reactions.
All of these hyaluronic acid products will last about the same amount of time, usually around 6 months though individual results may vary from one month to 9 months or more. The products are synthetically manufactured which means that the risk of allergic reaction is minimal. The major difference in the products is the size of the particle which will determine their effectiveness in various situations. Smaller particle sizes are useful for fine lines and wrinkles, such as those around the lips. Larger particle sizes are more useful for deeper folds, such as the nasolabial folds. The good thing is – if you don’t like what you see it will be gone without a trace in about 6 months. The bad thing is – if you like what you see it will be gone without a trace in about 6 months.
