Product FAQ
Is 20% niacinamide too strong for sensitive skin?
While potent, this formula includes soothing ingredients like panthenol and allantoin to reduce irritation—start slowly and patch test if needed.
Can I use this with vitamin C or AHA/BHA products?
Yes, but it’s best to alternate use or apply at different times (e.g., niacinamide in the evening, vitamin C in the morning) to avoid overstimulation.
How long before I see results?
Most users report visible improvement in brightness and texture within 2–4 weeks of consistent use, with continued benefits over time.
