Colour cosmetics products (commonly called make-up) are designed to add colour and thereby enhance the appearance of the skin. They are mainly used on, but not limited to, the face and have been part of human life for thousands of years – ancient Sumerian men are said to have invented and worn lipstick in the year 5000 B.C.
In more recent times, formulators have sought what they term dual benefit ingredients which don’t just decorate the face but contain cosmetics ingredients that provide a benefit to the skin.
