Before starting, you ensure your hands and nails are well cleaned. File your nails if necessary, so that there are no snags. By doing this you prevent damages on the face and risk of infection. With this you avoid damaging the skin and avoids the risk of infections.
Always work using clean materials (sponges, brushes, spatulas, water bowls) and change the water regularly.
Get the subject to put on any clothes beforehand that have to be put on over the head. Protect your models clothing with a hairdressing cape or a towel.
Store the make-up in a dry and cool place until the next time you use it.
The sponges are disposable so you can throw them away after use. If you do want to reuse them, first rinse them under the tap with some soap or shampoo or wash them in the washing machine (in a net bag or pillow case), set to at least 60°C.
You can clean brushes with water and soap or shampoo. Put the moist hairs of the brushes back into shape by hand after washing. Dry the brushes lying flat on a towel and do not place them upright, since that causes the moisture to run down into the shaft.
