Why do I need a brush to apply the products You need the brushes to apply our oxygen products which contain active oxygen. As soon as the cream touches the skin the oxygen reaction is triggered by the catalase enzyme in the skin. To avoid the absorption of the oxygen by the fingertips, we recommend applying all oxygen products with a brush. So the miracle effects of the oxygen are left for the areas where you really need them.

How can I clean the brush? It's sufficient to simply rinse the brush under water after each use.
