What is niacinamide?
Niacinamide is the quiet workhorse of modern skincare. It regulates oil production, supports the barrier, and fades dark spots over time. Most formulas use 4–10% concentrations, with 5% being the sweet spot for sensitive skin.
Key benefits
- Visibly minimizes the appearance of enlarged pores
- Regulates sebum for balanced, less shiny skin
- Fades post-acne marks and uneven tone
- Calms redness and soothes reactive skin
- Strengthens the skin barrier
Who should use it?
All skin types — especially oily, combination, acne-prone, and sensitive skin. One of the few actives safe to use during pregnancy.
How to use niacinamide
- Apply morning and/or evening after cleansing and toning.
- 2–3 drops of a 5–10% serum is plenty for the full face.
- Layer before heavier creams and oils.
- Always follow with SPF during the day.
Pairs well with
- • Hyaluronic acid

- • Salicylic acid

Frequently asked questions
Can I use niacinamide with vitamin C?
Yes. Modern formulas make this pairing common, though very sensitive skin may prefer to alternate vitamin C in the morning and niacinamide at night.
What percentage of niacinamide should I use?
4–5% is ideal for sensitive skin or first-time users. 10% gives maximum pore and oil benefits but can cause flushing in some people. Going higher offers no proven extra benefit.
How long before I see results from niacinamide?
Oil control and hydration improvements show within 2 weeks. Pore appearance and dark spot fading take 8–12 weeks of consistent use.
