Vitamin A (retinol) is a well-researched anti-aging ingredient that is essential in any effective product concept for the care of aging skin. This makes it an indispensable pillar of TetCode4. It effectively inhibits the enzymes that break down the valuable collagen that gives the skin its volume and elasticity. The result: collagen-building activities predominate, the skin breathes and remains naturally beautiful.

Only in the evening or at night, as vitamin A can be inactivated by light. Apply to the face immediately after cleansing. The serum can be used on its own, but it is ideal to finish with hyaluronic serum and face cream.

Please note the gradual application. Special note: Occasionally, slight skin irritation may occur at the beginning of use. We recommend gradually increasing the frequency of use during the first four weeks, e.g., only every second or third evening. After this adjustment period, the product 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 used as recommended in the evening.
