Hyaluronic acid is an element found in several tissues, such as the epidermis or cartilage, and is characterised by its incredible capacity to attract and retain water. It can absorb up to 1,000 times its weight in water.
The amount gradually decreases in the natural ageing process, and the skin loses hydration and elasticity and firmness. This also happens with the joints, where cartilage loses its water retention capacity and becomes stiffer.
This great moisturising power has made hyaluronic acid a substance widely used in cosmetic products and a great asset for skin with a certain degree of dehydration.
