To achieve a very nice child's make-up you have to use vegetable or water-based paints, which are not toxic and are ideal for children. Enjoy it!
1. Get the vegetable or hypo-allergenic water-based paint, Vaseline to stick the diamond and other elements you want to add.
2. Use makeup brushes that are soft and can be washed with hot water and soap.
3. Do not use too much water to prevent the makeup from dissolving.
4. Most important: remove all makeup from the face of children, before they go to bed. The skin of children has to breathe.
