Vitamin C
Vitamin C is a vitamin that must be ingested through the diet, because the human body is unable to synthesise it. Helps to raise immune-system barriers and reduces fatigue and tiredness. Vitamin C also has strong antioxidant properties: it fights the free radicals responsible for cellular ageing. It is also essential for collagen biosynthesis, because it is responsible for the transformation of two structural amino acids that are characteristic of this protein.
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.
