Prof. Dr. Volker Steinkraus is a passionate dermatologist. After completing his postdoctoral qualification in 1993 at the University Dermatology Clinic in Hamburg and a research stay at Thomas Jefferson University in Philadelphia, he took over as director of the Hamburg University Dermatology Clinic from 1995 to 1996.
In 1997, he founded the Dermatologikum Hamburg – today an international centre of excellence for dermatology, dermatological laboratory medicine, plastic surgery, laser medicine, vein and vascular medicine, and aesthetics. It now has several locations.
As an active dermatologist and dermatological surgeon, he is particularly interested in direct patient care and precise clinical diagnostics. In addition, he is deeply involved in training young doctors to become specialists in dermatology.
TetCode4® is a sophisticated system consisting of four components:
Modular and precise
Each active ingredient works where and when it is needed. The components complement each other: cleansing, nourishing, protecting – and improving the skin structure in the long term.
The Goal
The goal is skin that stays healthy, retains its natural radiance and feels strong every day.
Vitamins A, C and E are among the most well researched and effective substances in dermatology. Their positive effects have been scientifically proven for decades – and remain unrivalled to this day. That is why they are an integral part of TetCode4®.
Vitamin A (Retinol)
Stimulates collagen production, firms the tissue and smooths fine lines.
Vitamin C (L-ascorbic acid)
A powerful antioxidant that supports collagen production and can even out skin tone.
Vitamin E (Tocopherol)
Protects against UV-induced skin aging, improves skin smoothness and helps retain moisture.
Together, these three vitamins help to strengthen and protect the skin and preserve its natural radiance..
Niacinamide, a B vitamin, is a multi-talented ingredient for the skin – and one of the four pillars of TetCode4®.
It strengthens the cell architecture, improves structure and promotes elasticity. At the same time, it helps the skin to maintain its barrier function – the key to resilience and a healthy glow.
Botanicals represent the beneficial intelligence of nature. They make the skin supple, supply it with essential nutrients and support its barrier function. Fatty acids, vitamins and bioactive plant substances act as building blocks for strength and resilience.
TetCode4® uses selected plant oils such as jojoba and argan oil, skin-identical squalane and nourishing plant butters such as shea butter. Their finely balanced interaction moisturises, soothes and intensively nourishes the skin while strengthening its antioxidant protective shield.
A highly effective, natural treat – day after day.
Biomimetics are among the most exciting building blocks of modern research.They mimic nature's strategies – functions that have proven themselves over thousands of years in extreme habitats.This has led to solutions for cold, dryness or water shortage that can now be used in skincare.
Thanks to intensive research, this genius of nature can be deciphered and transferred: biomimetics such as ectoine, ceramides, squalane or extracts from heather and rye have a targeted effect, protect the skin and strengthen its resistance.
A pillar of TetCode4® that shows: nature is the best teacher.
