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. Already widely used in skin care, it protects and intensifies the natural color of eyelashes, creating the optimal condition for increasing their pigmentation.
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.
