Hyaluronic Acid

<< Back

The hyaluronic acid is not a synthetic product but a natural substance of the organism connective tissues. It can be found mainly in the skin, cartilaginous tissues, tendons, aorta walls, umbilical cord, etc. In terms of chemical classification, the hyaluronic acid is a glycosaminoglycan that gives elasticity and hydration to the skin, thus playing a very important role in the skin shape and resistance. The concentration of hyaluronic acid in connective tissues tends to decrease with aging and as a result the signs of skin weakness and relaxation become noticeable, together with deformations like wrinkles and folds in the face and body. As one of the elements in the synthesis of collagen and connective tissues, the hyaluronic acid with its anti-inflammatory and healing properties, not only increases the elasticity and hydration of the skin, but also contributes markedly to the body's defense against pathogens such as viruses and bacteria. Being a component of the organism tissues, the application of purified hyaluronic acid is not associated with risks of allergies or local inflammatory reactions which would otherwise be common complications in cases of application of synthetic fillers. The hyaluronic acid is also widely used in ophthalmology, otolaryngology and orthopedics, but due to its properties, it is considerated a very important substance especially for aesthetic treatments. The application of hyaluronic acid has become already quite widespread in the field of aesthetic medicine.
The injection of this substance restores plasticity, elasticity and tonicity to the skin, qualities which are lost with aging. In particular, the hyaluronic acid is applied to fill facial wrinkles, to plump and reshape the cheekbones, to fill the lips, and to correct various deformations (see also "Facial Treatments with Hyaluronic Acid").

After injection, the hyaluronic acid is slowly and gradually absorbed by the subcutaneous tissues without causing any side effects to the human organism. The molecules injected under the skin are attacked by enzymes called hyaluronidase and for this reason they are degraded within 24 - 48 hours and then absorbed by body tissues. In order to decelerate this physiological process, the hyaluronic acid is chemically treated with another substance (BDDE, 1,4 – Butanediol Diglycidyl Ether) whose function is to link to its molecules. The product is called cross - linked and takes its name after this process. In a few words, the hyaluronic acid applied as filler in aesthetic medicine is cross - linked to make possible a prolonged effect in the treated area. The achieved visual effect usually lasts 4 - 8 months, depending on the product, the characteristics of each individual person as well as the season (during the summer the effect is shorter due to high temperatures). Due to the above, it is advisable to repeat this treatment 2 - 3 times per year. However, even when the hyaluronic acid treatment is not repeated, the skin does not fully recede to its former condition and its hydration is enhanced for a long time.

Due to the safety and guarantee of its application in aesthetic treatments, and especially due to its wonderful and natural results in lips filling (see also “Lips Filling with Hyaluronic Acid”), the hyaluronic acid is nowadays one of the most recommended products in Europe and the United States by the international associations of plastic surgeons and the scientific community.

The treatment of skin deformations can also be performed with other SYNTHETIC products such as the liquid SILICONE, AQUAMID, RADIESSE, etc, which have permanent or long - lasting effects. Since these substances are recognized as foreign by the organism, there is an often present risk of ALLERGIC REACTIONS, INFECTIONS, subcutaneous GRANULOMAS, LOCAL INFLAMMATIONS, and PERMANENT FACIAL DEFORMATIONS. Therefore, KEIT® REFUSES THE APPLICATION OF SYNTHETIC MATERIALS in aesthetic treatments in full compliance with the highest standards of professional ethics and in full respect of all people’s health.

KEIT® applies high - quality hyaluronic acid which is produced by the most renowned Austrian (CROMA - PHARMA GmBH, http://www.croma.at), American (Allergan®, http://www.allergan.com) and Italian (IBSA Pharmaceuticals Italy, http://www.ibsa.it) international brands.
