Advances in the knowledge of the biochemical mechanisms associated with aging have led to the development of different approaches to reduce and repair their effects, in particular through the use of minimally invasive procedures. The use of materials with high biocompatibility and biodegradability has allowed to address different signs of skin aging, such as furrows, wrinkles, labial atrophy and loss of the superficial texture of the skin, as well as the restoration of the turgidity, elasticity and hydration of the skin. skin. One such substance is represented by hyaluronic acid, which plays a determining role in the hydration of the extracellular space due to its ability to attract water molecules, and also creates physiological conditions in the extracellular matrix for proliferation, migration and organization of skin cells.
