A lightweight leave-on serum with niacinamide (vitamin B3) at 5% and a small amount of zinc PCA. Niacinamide is one of the best-tolerated actives available: used daily it helps calm the look of redness, refines the appearance of enlarged pores and supports the skin barrier. The 5% level is chosen deliberately — higher concentrations offer little added benefit for most people and are more likely to irritate.

This is a supporting active, not a fast fix. Visible changes in tone and pore appearance build over weeks of consistent use, and it works best as one steady step in a routine rather than something you expect to feel working.

How to use

Cautions
