Hyaluronic acid fillers are gel-like substances used for filling wrinkles, facelift, deep skin hydration. The main ingredient of fillers is hyaluronic acid, a type of sugar that is present in most tissues of our body, joints, connective tissue, and skin. Hyaluronic acid is an intercellular fluid that has the ability to bind up to thousand times its weight in water. Our body uses it to hydrate tissues, as a lubricant, to enhance the immune response of tissues, and for reparation. All these properties were used when hyaluronic acid fillers were made, in order to obtain a means by which we can safely and effectively regenerate the skin, subcutaneous tissue, joints, urinary bladder and many other structures in the body.
Hyaluronic acid filler treatment
Different types of hyaluronic acid fillers have been developed in aesthetic medicine.
Each of the companies involved in their production has its own method of binding hyaluronic acid molecules, namely, based on the molecularcross-linking, the fillers may last between one month and 18 months.
Our natural hyaluronic acid is degraded and renewed in 7 days, while molecular cross-linking in fillers does not allow such a rapid degradation. Modifications of molecules include different structure of HA molecules, particle size, concentration of hyaluronic acid molecules.
What is the purpose of hyaluronic acid fillers in rejuvenation?
Hyaluronic acid can be used in different areas of the face and body in order to achieve different results such as:
* Cheek and lip enhancement
* Jawline and chin definition
* Full facelift with hyaluronic acid
* Filling the tissues around under-eye rings and minimizing under-eye rings
* Filling and removing fine or deep wrinkles on the face
* Tightening of ligaments on the face
* Compensating for the bony appearance of the face
* Improving the appearance of neck skin
* Reducing the depth of wrinkles on the décolletage area
* Hand rejuvenation using HA fillers
Hyaluronic acid fillers before and after
How long the achieved result will last depends on the density of the filler used as well as on the indication, i.e. the area where the filler was applied. In case of face volumization, the effects are achieved over 12 to 18 months. If a larger amount of fillers is used, the result can last up to 30 months, with a gradual loss of the result. An exception may be a large loss of fat tissue, i.e. weight loss. In that case, the applied hyaluronic acid is not lost but one’s own fat tissue is lost. The result of filling deep wrinkles, especially nasolabial folds, can last up to 5 years if facelift is performed during that period. Volume added to the lips can last between 6 months and 2 years, depending on the amount of material being applied as well as the filler brand.
What are the side effects of hyaluronic acid fillers?
Hyaluronic acid fillers are currently the safest fillers on the market. However, there are situations that can lead to complications. Complications that are transient in nature and include redness at the injection site, bruising, mild pain or swelling. These complications can last up to 7 days and are relatively common.
