How long does niacinamide take to work?
Visible improvements in oil control and skin tone usually appear within 4–8 weeks.
Can I use niacinamide every day?
Yes, niacinamide is gentle enough for daily use.
Is niacinamide good for acne scars?
It helps fade post-inflammatory hyperpigmentation (dark marks), but not deep textured scars.
