Karin Herzog Small Brush is recommended for use with face products containing oxygen to avoid active ingredients from being absorbed by the finger tips. Dr. Herzog's patented oxygen formulas contain active oxygen which is stabilized in the cream but changes to its more effective gas form upon contact with the skin.
Use Karin Herzog Small Brush to apply all Karin Herzog Oxygen products for the face. For ease of application, briefly moisten the brush under running water, as this will make spreading the treatment easier. After use, repeat this quick rinse. As oxygen is highly antiseptic, one does not have to worry about the brush being compromised. The oxygen in the treatments disinfects the brush with each use.
