Biomaterials have long been used as dermal fillers, as non-toxin options to facial cosmetic enhancement. After passing through a collagen phase, the market for dermal injections is now dominated by hyaluronic acid (HA). Outcomes are mostly satisfactory, except for one snag: they don't last forever.

 

The reason comes down to the fact that HA is constantly produced and degraded in the human body. Cells secrete it, while a specific enzyme called hyaluronidase degrades it. All told, HA injections are often repeated after about six months.

 

Chitosan and its derivatives are rugged and versatile polymers which can behave very similarly to HA, with one key difference: they degrade at a much slower rate in the human body. Oligo Medic is conceiving of an improved dermal injection for creating facial volume with the same satisfactory characteristics of HA, but fundamentally longer lasting outcomes.
