Niacinamide

The steady multitasker

What it does

Supports the skin barrier, helps regulate visible oiliness and can gradually improve uneven-looking tone.

Who it suits

Most skin types, especially oily, combination or mark-prone skin. Lower strengths are often enough.

How to start

Try 2-5% once daily. Higher percentages are not automatically better and may feel sticky or irritating.

What it pairs with

Comfortable with ceramides, hyaluronic acid, sunscreen and most treatments.

What to avoid

Pause if it repeatedly causes flushing or stinging. Do not keep layering duplicate niacinamide serums.

What to expect

Oil balance may feel better in weeks. Marks take longer and still need daily sunscreen.

Evidence, honestly

Well-studied for barrier support and sebum regulation. Evidence for pigmentation is promising but gradual.
