Is niacinamide safe for sensitive skin?

Yes! Niacinamide is actually one of the most gentle and safe ingredients for sensitive skin. It even helps strengthen the skin barrier that's often weak in sensitive skin.

Can I use niacinamide with vitamin C?

There's an old myth that they shouldn't be mixed, but recent research shows it's totally fine! If you're unsure, use vitamin C in the morning and niacinamide at night.

How long until I see results from niacinamide?

For oil control, you might feel it in 2-4 weeks. For brightening and pores, it usually takes 8-12 weeks. Be patient!

Why is my skin red after using niacinamide?

The concentration might be too high, or your skin might be sensitive right now. Try reducing the frequency or choosing a lower concentration (2-5%).
