Hyaluronic acid is a key player in aesthetic medicine. It can rehydrate, tone and smooth the skin, and can reshape the face by boosting volume in certain places, such as the cheekbones, temples or earlobes. It is also pain-free, since all hyaluronic acid formulations now contain a local anaesthetic.
What is hyaluronic acid?
It is a sugar that is naturally present and identical in all types of tissue: dermis, eyeballs, umbilical cord, etc. Vitreous and transparent by nature, it gives the skin its flexibility and tonicity. However various external factors – sun, smoking, pollution – and internal factors – age-related hormone changes – can reduce the quality and quantity of our hyaluronic acid stock. At age 50, we have lost around half of the stock we had as children! As a result, the skin does not look as fresh; it looks crumpled and wrinkles appear. To stop this damage, aesthetic medicine uses non-animal original hyaluronic acid injections. This fulfils the same function as the hyaluronic acid that is naturally present in our body: it traps water molecules, which generates volume and allows us to smooth fine lines and wrinkles in a flash. Depending on the area to be treated, the doctor will use a more or less cross-linked product, as cross-linking connects the molecules up with one another. The more cross-linked a product is, the more compact and harder it is. But injections do not only repair any damage; they also reboot our own hyaluronic acid production, as well as the production of another vital element for the skin: collagen.
