hexapeptide
Peptides are substances present in nature and in our body. They are like chains formed by many small rings linked to each other: these small rings are called amino acids. The peptide which is present in the eye cream Smiling Eyes is made up of 6 amino acids. It acts on expression lines that are particularly evident in the eye contour area, preventing their formation and improving the appearance of those already present. It also helps to prevent the loss of collagen, a protein that makes the skin toned and elastic.
Hyaluronic acid
This substance is naturally produced by our bodies to help moisturise and protect tissues. Hyaluronic acid can be found at high, medium or low molecular weight. High molecular weight hyaluronic acid: creates a protective film on the uppermost layer of skin, keeping water in tissues from evaporating and thereby preserving moisture over time. Medium molecular weight hyaluronic acid: increases the elasticity of the skin. Low molecular weight hyaluronic acid acts deeper in the skin and helps reduce wrinkles.
