The serum contains 20% niacinamide and is enriched with collagen-boosting copper ions. Niacinamide is extremely well tolerated and has been proven to be involved in many biochemical reactions that keep the skin healthy. As an all-rounder, it strengthens the skin barrier and has pigment-lightening, antimicrobial, pore-refining, sebum-regulating, and skin-protecting properties.
The result is a more even complexion and a fresher appearance.

Enjoy this product as a compelling addition to the highly concentrated serums in the TetCode4 line—hyaluronic acid, vitamin C, and vitamin A—with which it can be combined excellently.

In the TetCode4 routine, the evening Hyaluron Serum could be replaced by the Niacin Serum.
