Frequently Asked Questions
If you can't find the answer to your question, please don't hesitate to get in touch with our dedicated team.
Is Karin Herzog for all skin types?
Yes, if used correctly, Karin Herzog products are suitable for all skin types, even sensitive skin. All Karin Herzog products are paraben and preservative free and many do not even use any additional fragrances (check detailed ingredients). If your skin is sensitive, start using the products gradually. Apply the oxygen products every other night for two weeks, then increase to every night. Monitor the effect on your skin and possibly increase to using morning and night.
How should I apply Karin Herzog’s Oxygen products?
Directions vary for each product. However, we recommend that you apply the products that contain active oxygen with a brush rather than massaging them directly into the skin. This prevents the active ingredients being absorbed by the fingertips. Dr. Herzog's patented oxygen formulas contain active oxygen, which is stabilized in the cream but converts to its more effective gas form on contact with the skin. Application with a brush helps to ensure all of the transformative effects of the active ingredients are delivered directly to targeted area rather than being absorbed by your hands.
Can I mix Karin Herzog products with products from other brands?
We don't recommend mixing Karin Herzog products with other brands: the stabilized oxygen in our products may cause some ingredients (preservatives for example) to penetrate deeper than they are designed to, thus causing unwanted reactions. If you wish to continue using your usual cleansing milk and lotion, rinse your skin with pure water or Tonic Lotion before applying a Karin Herzog cream with oxygen.
