Niacinamide is a water-soluble form of vitamin B3 (also called nicotinamide). It's one of the most thoroughly researched ingredients in modern skincare and works on multiple skin pathways at once — calming redness, regulating oil, brightening uneven tone, and supporting the barrier.
B3 is the skincare ingredient that gets along with everyone. It calms what's red, evens what's uneven, and pairs with almost any other active.
The clinical evidence for Niacinamide is strongest in these areas:
Almost every skin type — combination, oily, dry, and sensitive skin all generally tolerate niacinamide well. A reliable starting active for beginners.
At high concentrations (above 10%), some sensitive skin may experience flushing or mild irritation. Start at 5% if you've never used it.
Build a complementary routine — these actives layer cleanly with Niacinamide.
No major incompatibilities reported. Start with one active at a time, patch test, and wait 24 hours before reintroducing a second active.
Niacinamide appears in 3 products from the SSKENN catalog.
"Helps visibly even skin tone, support a healthy barrier, and reduce the appearance of enlarged pores with consistent use."
