- a rosy skin color (such as is available by staying in the open air) is considered by consumers to be healthy and therefore desirable, whereas a pale complexion is generally not as desirable.
- the object of the present invention was to provide skin-care preparations and preparations for the care of naturally aged skin, wherein the preparations should care for and beautify the external appearance of the body.
- simarin is the technical name of a plant extract from the fruits of the milk thistle (Silybum marianum), which can contain the three substances silybin, silydianin and silychristin in different concentrations.
