Niacinamide & Barrier
Niacinamide and barrier-support actives
Niacinamide, panthenol, ceramides, peptides — calming ingredients that pair with almost everything, and the rare cases where they don't.
The 'barrier club' of ingredients regulates sebum, calms redness, and supports the skin's natural lipid matrix. They're the safest layer in your routine — but a few oral medications still need a heads-up.
