Collagen is a vital molecule which helps to improve general health. The complex protein is found in many of our organs – and makes up 6 % of your own body weight, determines the elasticity as well as strength of the connective tissue. Collagen rejuvenates your body delivering a silky smooth feel to your skin.

Hyaluronic acid is a multiple sugar (polysaccharide), which can be characterized by its moisture-binding capabilities. One gram of the molecule can bind up to 6 liters of water. Hyaluronic acid is the main component of our synovial fluid and ensures that our joints remain steadfast under heavy loads. In the skin, hyaluronic acid works like a natural water reservoir, providing it with more elas-ticity. Every year the body loses about 1 % of its own hyaluronic acid content. Paired with a simultaneous collagen breakdown, the disappearance of HA leads to loss of skin elasticity, volume and the appearance of wrinkles.

Christian Berlin's Iris Elixir uses a low molecular weight hyaluronic acid, enabling it to be absorbed through the lymphatic system. The acid is then carried to the cell tissue where it sediments. A study of the biochemical properties of HA shows that the oral intake significantly improves the skin’s moisture level. In another study on the long term effects, scientists from the School of Medicine in Thessaloniki and the University Hospital Basel have shown that hyaluronic acid exponentially decreases the aging process of the skin.
