Using these Maqpro liquid watercolours is easy. First, choose the size of the bottle that suits your needs. For face painting, you can use a fine - tipped brush to create detailed designs. Just dip the brush into the watercolour and start applying it to the skin. If you're using it for artistic make - up, you can be more creative with the application. To remove the watercolours, simply rinse your face or the painted area with water. If there's a bit of residue, you can use a mild soap. When it comes to storage, keep the bottles in a cool and dry place. Make sure the lids are tightly closed to prevent the watercolours from drying out. Also, don't let the watercolours come into contact with eyes or open wounds. If you have sensitive skin, it's a good idea to do a patch test first.
