If children have skin irritation or small cuts on their faces, you can also do the painting on the hand.
WATER MAKE-UP

Grimas Water Make-up (Pure) is an unperfumed, gluten-free water-based make-up, intended for face-painting and body-painting.
Pure means that the product in question does not contain any chemical preservatives (such as parabens) or halogenated organic compounds.

Water Make-up works just like watercolour paint. The best way to apply Grimas Water Make-up (Pure) and Water Make-up Pearl Pure is to use a brush. Use the brush and a little water to soften the make-up and make it a bit pasty. Test the colour intensity on the hand. Apply the Water Make-up into the hairline (do not forget the ears and the neck); this will prevent a mask-type effect. Don't work too dry, but do not use too much water.

This example makes use of the principle of 'aging'.

Shadowing/lining
Important areas for shading are the eye sockets, the temples, the side of the nose and below the cheekbones. The vertical frown wrinkle and the naso-labial ('nose-lip') fold are also important areas to shadow.

If you extend sharp lines, for example by extending the naso-labial fold line downwards, this will give a negative and even rather mean effect. The longer the line, the more severe the character will appear. The naso-labial fold line can be found more easily if you ask the person whom you are making up to do a grimace.
