Frequently Asked Questions
Can I use this 15% Niacinamide serum daily?
Yes, but due to its high concentration, beginners should start by using it 2–3 times a week and gradually build up to daily use as tolerated.
Is it suitable for sensitive skin?
Because of the high 15% concentration, sensitive skin types should patch-test first and introduce it slowly into their skincare routine.
Can I pair this with Vitamin C or AHA/BHA exfoliants?
To avoid potential irritation from active ingredients, it is best to alternate usage (e.g., use AHA/BHA or Vitamin C at night and Niacinamide in the morning).
