Special Note: (1) Die empfindlichen Vitamin C Konzentrat-Kugeln können evtl. durch die Erschütterung beim Transport ihre ursprüngliche runde Form verlieren. Dies beeinträchtigt die Eigenschaft und Wirksamkeit des Produkts in keinster Weise. Das Pulver können Sie mit der Aktivatorflüssigkeit auflösen und wie empfohlen auftragen.
(2) Durch die hohe Konzentration des Wirkstoffs und den kristallinen Charakter des Niacinamids kann es je nach angewendeter Produktmenge nach dem Antrocknen des Wirkstoffs zu harmlosen weißen Streifenbildungen auf der Haut kommen. Durch das anschließende Auftragen und Einarbeiten von Hyaluron und/oder einer Pflegecreme (Face Care Light, Medium oder Rich) verschwinden diese Streifen sofort.

As an effective antioxidant, vitamin C (L-ascorbic acid) plays a crucial role for all human organs. It is particularly important for the healthy structure of the skin because it enables the biosynthesis of collagen, the main component of the dermis. A vitamin C deficiency leads to instability of the connective tissue. The sensitive power vitamin is enclosed in a protective bead and only dissolved and activated with a special activator liquid immediately before application. This allows the full potential of one of the most important anti-ageing vitamins to be exploited - without compromise. The serum firms the skin, reorganises the skin matrix and creates a pure and fine complexion.

Vitamin A (retinol) is an excellently researched, highly regarded anti-ageing substance, which is a must for any effective product designed to care for skin that is showing signs of ageing. This makes it an essential part of TetCode4. Vitamin A is effective at inhibiting the enzymes that break down precious collagen, which lends the skin volume and elasticity. This means the collagen-building activities prevail, so the skin can breathe a sigh of relief and remain naturally beautiful.

Nur abends bzw. nachts, da Vitamin A durch Licht inaktiviert werden kann. Direkt nach der Reinigung auf das Gesicht auftragen. Das Serum kann für sich alleine angewendet werden, ideal ist jedoch das zusätzliche Finish mit Hyaluron Serum bzw. Niacin Serum 20% und Gesichtscreme. Bitte einschleichende Anwendung beachten.
Special Note: Occasionally, some minor skin irritation is experienced when the product is first used. We recommend introducing the serum gradually during the first four weeks, e.g. only using it once every two or three evenings. After this acclimatisation phase, it can be used every evening without any problems. Please note that retinol can make the skin more sensitive to UV radiation. However, this is irrelevant when it is used in the evening, as recommended.
free from artificial fragrances, silicone, microplastics, acrylates and parabens
Only use in the evening or at night because vitamin A can be rendered inactive by light. Apply to the face immediately after cleansing. The serum can be used on its own, but should ideally be followed by hyaluronic serum or niacin serum 20% and face cream.

Hyaluron specialises in moisture retention and works effectively all the way down to the deeper layers of skin. It reduces irritation and plumps up the skin, making it a must for any bathroom cabinet worth its salt. The serum from the Prof. Dr. Steinkraus range is particularly effective: with 2.5% hyaluron, it is highly concentrated and contains all three molecular sizes of hyaluron. This is crucial because it offers you outstanding penetration twinned with both immediate and longterm effects. You can use hyaluron serum on its own, but we recommend applying it with the vitamin A in the evening or C serums. The combination results in synergies that significantly enhance the efficacy of the individual products. This delivers a real boost for your skin.

After cleansing and applying vitamin C (in the morning) or vitamin A (in the evening), apply the hyaluron serum sparingly and leave it on long enough. Only when hyaluron has bonded well with the skin can additional face care, foundation or make-up be applied.

The serum contains an effective concentration of 20% niacinamide and is enriched with collagen-strengthening copper ions. Excellently tolerated, niacinamide has been shown to be involved in a great many biochemical reactions to maintain healthy skin. As an all-rounder, it strengthens the skin barrier, has pigment-brightening, pore-refining or sebum-regulating as well as skin-protecting and thus protective properties. As an effect, you will experience a more even complexion and a fresher appearance of the skin. Enjoy this component as a convincing complement to the highly concentrated serums of the TetCode4 line hyaluron, vitamin C and vitamin A, with which you can combine it perfectly.

As part of the TetCode4 routine, the niacin serum 20% can replace the evening hyaluron serum.
