Prof. Dr. Steinkraus Collection | TetCode4®: dermatological science for an intelligent beauty ritual
The Prof. Dr. Steinkraus collection is born from the clinical rigor and aesthetic sensibility of an international reference in dermatology, and is built around a clear philosophy: caring for the skin with precision, respect and visible results. Its patented TetCode4® system proposes a modular architecture of active ingredients, where each one works where and when it is needed, complementing each other to cleanse, nourish, protect and improve skin structure over the long term. This holistic vision — integrating biomedical science, the intelligence of nature and formulation excellence — places the brand at the heart of purposeful luxury cosmetics: healthy, radiant and strong skin every day.
The core of TetCode4® is made up of four active worlds that interact with one another to offer complete, evolving skincare. The first, the universe of vitamins A, C and E, brings together three high-performance classics with decades of dermatological evidence: vitamin A (retinol) stimulates collagen production, improves firmness and smooths fine lines; vitamin C (L-ascorbic) acts as a powerful antioxidant, supports collagen synthesis and helps even out skin tone; vitamin E (tocopherol) protects against photoaging, improves smoothness and helps retain moisture. Together, they strengthen and protect the skin, preserving its natural radiance. In the collection, their presence is expressed in antioxidant and firming serums and creams that fit into a daily beauty ritual focused on prevention and correction.
The second pillar, niacin (vitamin B3), acts as a regulator of the skin barrier and the skin's immune system. In smart formulations, niacinamide helps reduce sensitivity, reinforce barrier function, improve texture and minimize the appearance of pores, bringing balance to combination skin and soothing support to reactive skin. Incorporated into gentle cleansers, lotions and daytime treatments, it enhances tolerance and evens out complexion, reinforcing an approach to luxury cosmetics that prioritizes comfort and efficacy.
The third world belongs to botanicals: plant extracts selected for their potency and purity, providing polyphenols, sugars, lipids and micronutrients with antioxidant, soothing and revitalizing action. These plants, studied for their resilience in demanding environments, infuse the formulas with a refined sensory character and a balanced functional response. In this area, the collection relies on botanical oils and complexes to nourish without overloading, support elasticity and soften reactivity, fostering a beauty ritual that feels elegant, enveloping and deeply comforting.
The fourth universe, biomimetics, demonstrates that nature is the best teacher. Molecules inspired by evolutionary strategies — ectoin to protect against environmental stress and dehydration; ceramides to rebuild the barrier; squalane for light, biocompatible emolliency; heather and rye extracts for resilience against cold and dryness — are incorporated into the collection with the aim of mimicking mechanisms proven over thousands of years and translating them into tangible benefits: more resilient, hydrated and balanced skin. This biomimetic approach can be felt in textures that embrace the face like a second skin, in polished finishes that feel weightless, and in results that last well beyond application.
The Prof. Dr. Steinkraus collection offers key pieces for a complete premium routine: cleansers that respect pH and preserve the barrier; toners and essences that optimize skin receptiveness; serums with vitamins A, C, E and niacinamide that address tone, texture and firmness; biomimetic treatments rich in ceramides and ectoin that seal in hydration and shield against the environment; and day and night creams that coordinate antioxidant protection and regeneration. Each product is designed to fit flexibly into daytime and nighttime habits, allowing you to personalize your care according to season, climate, sensitivity and goals (radiance, anti-aging, comfort).
On the sensory level, the brand's luxury cosmetics are expressed through exquisite textures: silky emulsions that melt in without residue, fast-absorbing gel-creams with a "second skin" effect, balms that provide instant comfort, and highly penetrating water-based serums that deliver a technical freshness. The olfactory signature is discreet and modern, designed to accompany rather than interfere — a detail consistent with the dermatological focus and the pursuit of compatibility with sensitive skin. Application is conceived as a beauty ritual: upward movements to stimulate and redefine, gentle pressure to activate microcirculation, mindful breathing to turn the routine into a moment of wellbeing.
The visible results that TetCode4® delivers are progressive and reliable: immediate hydration and softness; within weeks, finer texture, more even tone and improved bounce; in the medium term, reinforced firmness and smoothed wrinkles; over the long term, skin that is stronger against aggressors (UV radiation, temperature changes, pollution) and a serene radiance that is the hallmark of a healthy barrier. This path of continuous improvement is supported by effective ingredients and optimal proportions, avoiding excess and prioritizing consistency in skincare.
