Water Make-up works just like watercolour paint. 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. Don't work too dry, but do not use too much water. Water Make-up (Pure) dries within 15 seconds. If you do not want the colours to mix, be sure to wait for the first layer to dry before you work over it.
Hint: Regularly change the water you rinse your brushes in and preferably work with two water bowls: one for light and one for dark shades. Cotton buds
