As far back as the 1950’s Professor Cluver proved that every time we go into sunlight our vitamin A is significantly depleted, both in the skin and blood. Daily replacement is therefore critical to combatting signs of skin ageing. There are many forms of vitamin A in skin care, some are more stable than others, but what they have in common is that they are all sensitive to light and air. This means they need to be formulated in a special environment and packaged to preserve the contents. In addition, a step-up system is kinder to the skin, enabling us to challenge the skin to be even better.
