What is Hyaluronic acid?
Hyaluronic acid is an anionic, nonsulfated glycosaminoglycan distributed widely throughout connective, epithelial and neural tissues. It is unique among glycosaminoglycans in that it is nonsulfated forms present in millions particles weight at the plasma membrane.
Hyaluronic acid is found in many tissues of the body, such as epidermis, derma and cartilage. It is an important component of articular cartilage as it responsible for its resilience (resistance to compression) where it is present as a coat around each cell. It is also a major component of epidermis and derma, where it is involved in tissue protection, resistance and repair. When the skin is exposed to excessive UVB rays, smoke, pollution and in the natural ageing process, the cells in the skin stops producing as much hyaluronan and, specially with the ageing, it increase the rate of its degradation.
Moreover, hyaluronic acid has been used in the medical field in other to attempts to treat osteoarthritis of the knee via injecting it into the joint. It was also approved for use in eye surgery (such as corneal transplantation, cataract surgery, glaucoma surgery, and surgery to repair retinal detachment).
Therefore, we can assume that hyaluronic acid is well suited to biomedical applications on the cartilage, derma and epidermis with optimal results, biocompatible material, fast and comfortable procedure, save and non permanent effect.
The linear hyaluronic acid has a relatively short life after injection into the body. Special manufacturing techniques have been developed to extend the length of the hyaluronic acid chain and stabilise the molecule for longer results after the medical applications.
So, it was created a chemical procedure that introduced a protein into the solution creating the well known cross-linking hyaluronic acid.
The degradation of the hyaluronic acid became much slower and the results obtained once injected was definitely longer comparing with the linear type.
