## Questions & Answers

**Q: For Beginners : Is 10% Niacinamide suitable for daily use / multiple concerns?**
A: Yes. 10% Niacinamide supports multiple concerns like uneven tone, texture, and excess sebum. Sensitive skin: start with 1–2 drops, 2–3x/week, then increase gradually as your skin adjusts.

**Q: For Sensitive Skin: Is 10% Niacinamide Serum suitable for sensitive skin?**
A: Yes. This serum passed a skin irritation test with a 0.0% irritation score and is formulated to be gentle. Since skin varies, start with a small amount 2–3x/week and increase gradually as your skin adjusts.

**Q: Can I use 10% Niacinamide Serum with Vitamin C, Retinol, or AHA/BHA?**
A: Yes. It pairs well with vitamin C, retinol, AHA/BHA, hyaluronic acid, and peptides. If combining strong actives causes stinging or redness, reduce frequency or use them at different times of day.

**Q: How long does it take to see results from a 10% Niacinamide Serum?**
A: Results vary by skin type and discoloration level. In clinical testing, tone changes appeared around 2 weeks, while set dark spots take longer. Use consistently for at least 2–4 weeks, adjusting based on your skin's response.
