Niacin Serum 20%

This serum contains 20% niacinamide and is enriched with collagen-strengthening copper ions. Excellently tolerated, niacinamide has been proven 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, antimicrobial, 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.

- Niacinamide (vitamin B3) is the core ingredient of this serum with 20%. It has a protective effect and strengthens regenerative functional processes of the skin.

- The 0.3% hyaluronic acid has a hydrating effect and improves the skin's feeling.

- The copper gluconate strengthens the collagen.

- Calluna Vulgaris (heather) provides a high concentration of bioactive polyphenols that strengthen the protective function of the skin.

- Secale Cereale (rye) has an astringent and antimicrobial effect and supports the skin's natural exfoliation processes.

(13) Niacin Serum 20% is a stand-alone product and can be easily incorporated between all skincare steps after cleansing. Before applying the face care (e.g. Face Care Light, Medium or Rich), the Niacin Serum should always be allowed to absorb for 2-3 minutes. In the TetCode4 routine, the evening Hyaluron Serum could be replaced by the Niacin Serum.

We do not believe that CLEAN products are a must or the answer to every skin care problem. But we want to provide a quick guide for those who want to avoid certain ingredients.

Our Clean Beauty concept is primarily defined by the ingredients you won't find in the products with the CLEAN icon:

BHA (butylated hydroxyanisole), BHT (butylated hydroxytoluene), chemical sunscreens, EDTA, ethanolamines, ethoxylated ingredients (Ceteareth-20, emulsifying wax, PEGS, polysorbate-20, polysorbate-40, steareth-20, sulfates), formaldehyde, methylchloroisothiazolinone and methylisothiazolinone, methylcellulose or 2-methoxyethanol, nitro- and polycyclic musk, parabens, petrolatum and paraffin, phthalates, resorcinol, silicones, animal by-products (with the exception of lanolin and beeswax), toluene, triclosan and triclocarban.

With this icon you can see at a glance which products meet the standard of our CLEAN Guide.
