Ageing is a natural but complex process. Our cells age as we do and, with time, they are not able to replicate and, as a result our skin begins to look tired and wrinkles and fine lines start appearing. Medecine nowadays uses localised treatments with stem cells to improve the aesthetic appearance. These cells are responsible for the production of collagen, elastin and hyaluronic acid and they are usually injectied into the skin with micro-needling techniques.
