Does niacinamide work for pigmentation?

Yes. Niacinamide works by inhibiting the transfer of melanin from melanocytes to skin cells, reducing the appearance of dark spots and uneven skin tone. At 5-10% concentration, it shows visible improvement in 6-12 weeks of consistent daily use.

How long does niacinamide take to work on dark spots?

Most people see early improvement in skin texture and redness reduction within 3-4 weeks. Visible brightening and fading of dark spots typically appears at 6-8 weeks. Significant improvement in overall skin tone is usually seen at 10-12 weeks.

What percentage of niacinamide is best for pigmentation?

5% niacinamide is clinically proven to reduce pigmentation. 10% can deliver faster results but may cause mild flushing in sensitive skin. Start with 5% and increase to 10% if your skin tolerates it well.

Can I use niacinamide with vitamin C?

Yes. Niacinamide and vitamin C are compatible and work through complementary mechanisms. The most common approach is to use vitamin C in the morning and niacinamide in the evening, though they can also be used in the same routine.
