Hyaluronic Acid is a material that exists in healthy tissues, namely in collagen and is responsible for the elasticity of the skin. Its unique properties retain water and play a crucial role in skin hydration. Modern HA is the product of laboratory manufacture, hence it is completely safe and free of any allergic reaction, while its duration is over a year. It can be used to "fill" wrinkles of the face, in areas such as between the eyebrows, nose lines, wrinkles of the edge of the mouth and neck.

It can also be used to increase the volume of lips and accentuate their outline. The material is absorbed slowly, but the treatment can be repeated if needed.
