Juvederm is one of the leading FDA-approved dermal fillers recommended by experienced dermatologists and plastic surgeons. It is an ideal, minimally invasive treatment for moderate to severe facial folds and wrinkles. Juvederm is primarily based on hyaluronic acid, which is a natural substance found in the muscles, tendons, and skin of human beings and other mammals.
The most important use of Juvederm lies in removing deep smile lines or nasolabial folds, which are skin creases running from the corners of the mouth to the nose. It also serves as an effective lip augmentation agent, and helps to fill hollow cheeks and scars on the face. Sagging or drooping skin can be rejuvenated and made more elastic when volume is added to it with hyaluronic acid.
The effectiveness of Juvederm lasts for anywhere between six and nine months. This is because hyaluronic acid, which is a biocompatible compound, eventually gets absorbed by the body. This requires a patient to undergo repeat treatment to maintain the results over a longer period of time. If the patient receives a supplemental treatment a few weeks after the Juvederm injections are administered, the duration of the results can be improved.
Juvederm is a cross linked compound according to its manufacturers. Cross linking is a process to bind the isolated chains of hyaluronic acid chemically so that it converts into a gel to improve its longevity once it is injected inside the dermis. In its natural form, hyaluronic acid is a liquid, and the body can metabolize it in half a day. Cross linking process is the key to prolong the effectiveness of the treatment.
Properties of Hyaluronic Acid
For cosmetic and dermatological applications, Juvederm is an excellent alternative because hyaluronic acid can absorb up to a thousand times its own weight in water. This helps to add new volume underneath the surface of sagging facial skin. Hyaluronic acid has a natural property to bind with the skin collagen and elastin to transfer more basic nutrients to the skin. This helps the patient’s face to take on more youthful aspects.
A study conducted by researchers at the University of Michigan found another unique property of hyaluronic acid. It tends to stretch skin cells known as fibroblasts in such a way that the skin is naturally induced to produce new collagen. The new collagen replaces the collagen depletion that may have occurred with age. This results in reduction of facial wrinkles and creases. The same study pointed out that hyaluronic acid also tends to prevent the breakdown of existing collagen.
