What It Does
Niacinamide (vitamin B3) supports the skin barrier by boosting ceramide production, may help regulate sebum output, and has mild anti-inflammatory properties. At concentrations of 4-5%, it may also help improve the appearance of enlarged pores and mild pigmentation over time.
Best Use Cases
- Oil control and pore appearance
- Mild pigmentation and uneven tone
- Barrier support and hydration
- General skin health maintenance
Who May Benefit Most
Most skin types benefit from niacinamide. It is particularly useful for oily, combination, and sensitive skin types looking for a low-irritation active.
Cautions
Generally very well tolerated. Some individuals experience mild flushing at higher concentrations (10%+). Start with 4-5% if you are new to actives.
Common Mistakes
- Using excessively high concentrations (10%+) without need
- Expecting dramatic results for deep pigmentation — niacinamide works best for mild concerns
- Layering too many actives at once instead of keeping the routine simple
Combines Well With
- Hyaluronic acid
- Ceramides
- Retinol (used in the same routine)
- Sunscreen
May Combine Poorly With
- Vitamin C at very low pH (older concern, generally fine in modern formulations)
Realistic Timeline
Visible improvements in oil control and texture may appear within 4-8 weeks. Pigmentation changes are typically slower, often 8-12+ weeks.
