Sleep plays a major role in preparing the body for an alert and productive tomorrow. But sleep is not a period of inactivity.

Colouring the lips is certainly not a new idea. It was practiced as early as 3500 BC.
In the past, a natural dye was used to paint lips. It was not until the 17th century that lipstick manufacturing really took off. The lipstick was made of mixtures that included pig fat and red sandalwood(檀香油). It was kept in tiny pots and applied with a colouring stick.
Lipstick was invented and first presented by Parisian perfumeries (香水制造商) in Amsterdam. But these "little red sausages" were less practical. They were wrapped in silk paper and the ends had to be broken off before each use. They also did not come cheap.
