From wiki:
http://en.wikipedia.org/wiki/Rouge_(cosmetics)
Nowadays, rouge generally consists of a red-coloured talcum-based powder (滑石) that is applied with a brush to the cheek. The colouring is usually either the substance of safflor (the petals of safflower), or a solution of carmine in ammonium hydroxide and rosewater perfumed with rose oil.
It seems, rouge is made from plants, chemicals and minerals.
I think your friend is confused rouge with lipsticks. A food additive named "carmine" is used in manufacturing lipsticks. It is a red dye and used in many food stuff such as candies, ice-cream, jellies ... etc.
Carmine is made from insects.
As long as you are not allergic to it or you are a vegetarian. I don't think you should worry too much.
For more information about carmine, check out the following web site:

In case you want to know the insect, its name is cochineal.
