Hyaluronic acid is present in everyone’s body and fulfils various functions. One of these functions is to ensure sufficient resilience and suppleness of the skin. As the skin ages, hyaluronic acid is broken down faster while the production of this substance by your own body slows down. The result is a softer skin, sometimes with fine wrinkles. This is also the reason why many anti-ageing skin creams contain hyaluronic acid.
