Concept

Scientifically proven, intelligently simplified: our modular system provides you with a clear routine and visible results. Each element fulfils a specific function, and all complement each other perfectly. Fewer products, maximum quality and precision – for noticeably greater effectiveness.

Competence

Four decades of dermatology at the highest level and experience gained from hundreds of thousands of patient contacts. The skincare concept developed by Prof. Dr. Volker Steinkraus focuses on the essentials: simply structured, evidence-based and supported by authentic dermatological expertise.

Science

Each of our products follows a rigorous dermatological development process. Our TetCode4^® principle combines four groups of ingredients: (1) vitamins A/C/E, (2) niacinamide, (3) plant extracts and (4) biomimetics – carefully combined for reliable results. No trends and no randomness, just proven ingredients for the skin.

Made in Germany

All Steinkraus products are manufactured in Germany under direct control and using transparent processes. This means short distances, high standards and reliable quality. No outsourcing and no compromises; quality assurance takes precedence over cost pressure.

Sustainability

We develop and package our products with respect for the environment. Our range remains deliberately limited: only products with genuine benefits and proven effectiveness. With every product sold, we actively support moorland conservation.

Application Concept

The secret: the right active ingredient at the right time.
Our application concept follows a clear principle: modular and serial. Modular means that each step can stand alone and can be omitted if necessary. Serial means that the order must remain unchanged. The products with the TetCode4^® formula are precisely tailored to this: they improve the skin structure step by step in a targeted manner – flexible in application, but always scientifically precise in their composition.

Hyaluron Serum

Inge B.

Use the hyaluronic serum in the morning and evening – even under the eyebrows. It absorbs quickly, provides intense moisture and makes the skin appear plumper and smoother. For me, it's an essential part of my skincare routine!

Pia T.

Good consistency, absorbs wonderfully. Non-sticky. Versatile. Can be used on its own or as a base for other products. Skin feels nourished and looks even. A treat for skin and soul!

The niacin serum is a real game changer! It refines pores and soothes the skin. Super gentle and ideal for daily care.

I've been using it for over a year. It's the first serum where I can actually see results.

Angelika S.

After just one week, I noticed a positive change! My skin feels firmer! It just feels wonderful on my skin!

Sina H.

I have tested many products and can therefore say that Prof. Steinkraus' products are excellent. I have combination skin and, at almost 40, still tend to have blemishes and spots, but I tolerate everything very well.
