FAQ
Oxygen Skincare Technology
What is oxygen skincare and how does it benefit the skin?
Oxygen skincare delivers stabilized active oxygen directly to the skin, boosting cellular regeneration, enhancing hydration, and promoting a radiant complexion. Karin Herzog is the pioneer in this skincare innovation, offering scientifically formulated creams that release oxygen upon contact with the skin.
How does Karin Herzog stabilize oxygen in its creams?
Dr. Paul Herzog developed a patented and groundbreaking method to stabilize active oxygen in an emulsion form. This innovation allows the oxygen to remain inactive in the cream until it comes into contact with the skin, where it is gradually released in controlled doses. Unlike oxygen that evaporates quickly, this stabilized form penetrates deeply beneath the epidermis, promoting cell regeneration, detoxification, and improved oxygenation of the tissues. This technology ensures maximum effectiveness, safety, and prolonged results, making it ideal for various skin concerns including dullness, aging, acne, and uneven tone.
Is oxygen skincare suitable for all skin types?
Yes! Our oxygen-infused formulas are ideal for all skin types, including oily, dry, and sensitive skin. The natural delivery of oxygen helps balance sebum production, soothe inflammation, and improve skin texture.
Ingredients & Formulations
Are Karin Herzog products free from parabens and harsh chemicals?
Yes, all our products are formulated without parabens, sulfates, or harmful additives. We use clean, skin-friendly ingredients that support long-term skin health.
Are Karin Herzog products vegan and cruelty-free?
Most of our skincare line is vegan and all products are 100% cruelty-free. We do not test on animals, and our formulas respect both the environment and your skin.
What makes Karin Herzog different from other skincare brands?
We are the only brand to offer stabilized oxygen skincare, created by a Swiss doctor. Our science-backed approach combines medical-grade innovation with luxurious, spa-quality care.
Skincare Concerns & Benefits
Can Karin Herzog help with anti-aging?
Absolutely. Our oxygen-enriched creams improve skin elasticity, reduce fine lines, and stimulate collagen production—making them powerful anti-aging solutions for mature or dull skin.
Application & Usage
How do I apply oxygen creams for the best results?
Do not massage the cream. Apply a thin, even layer to clean, dry skin using a brush or fingertips and let it absorb naturally. The oxygen will self-penetrate without manual application.
Can I use Karin Herzog with other skincare brands?
Yes, but for optimal results, we recommend using a full Karin Herzog routine. The oxygen formulas are designed to work synergistically with our cleansers, masks, and moisturizers.
How long before I see visible results?
Yes, but for optimal results, we recommend using a full Karin Herzog routine. The oxygen formulas are designed to work synergistically with our cleansers, masks, and moisturizers.
Can I apply oxygen products to eyelashes or eyebrows?
It’s not recommended due to the potential lightening (bleaching) effect on hair.
Sensations & Skin Reactions
Why is my skin dry after applying oxygen treatments?
The skin needs time to adapt to the normalizing action of active oxygen. For dry skin, we recommend using a face oil like "Vita-A-Kombi Oil" to boost hydration and anti-wrinkle effects. You can also use a comfort cream such as "Additional Sweet", "Vitamin H", or "Day Protection" (which includes SPF 30).
It’s my first week using oxygen treatments. Why do I feel tingling?
A slight tingling is normal, especially with higher oxygen percentages (e.g., Silhouette 4%, Vita-A-Kombi 3 with 3% oxygen). This is a sign that oxygen is penetrating deep into the skin. The sensation fades over time as your skin adjusts. If you don’t feel tingling, it doesn’t mean the product isn’t working—responses vary by skin type.
Why do I notice more blemishes when I start using the products?
This is completely normal. Active oxygen works deep under the skin to eliminate bacteria, toxins, and cell debris. As your skin normalizes, some imperfections may temporarily surface before disappearing. This proves the product is working. It's important to continue daily use for best results.
Pregnancy & Safety
Can oxygen-based products be used during pregnancy or breastfeeding?
Yes, they are generally safe to use during pregnancy and breastfeeding. However, since every pregnancy is unique, we recommend consulting your doctor if you have any concerns.
Product Storage
How should I store the products?
Keep them tightly closed, away from light and heat sources.
