Why This Combination Works
Vitamin C
Targets dullness and dark spots. Best used in the am.
Niacinamide
Targets oil balance and pores. Best used in the either.
Modern research has debunked the myth that these ingredients can't be used together.

Frequently Asked Questions
Can you use Niacinamide and Vitamin C together?
+
Yes, absolutely. Modern research shows that Niacinamide and Vitamin C are highly compatible. Niacinamide actually helps stabilize Vitamin C, reducing its rate of oxidation and enhancing its overall brightening and barrier-repair efficacy.
Is Vitamin C and Niacinamide safe for rosacea?
+
Yes, but choice of formula matters. If you have rosacea, avoid high concentrations of pure L-ascorbic acid, which is highly acidic and can trigger flushing. Instead, look for gentle Vitamin C derivatives like Sodium Ascorbyl Phosphate or Tetrahexyldecyl Ascorbate, paired with niacinamide to help soothe redness and support the skin barrier.
How do you layer Vitamin C and Niacinamide?
+
The general rule is to apply the product with the lower pH first. If using pure Vitamin C (L-ascorbic acid) and a niacinamide serum, apply the Vitamin C first, wait 5-10 minutes for it to absorb, and then apply niacinamide.
- —Start with lower concentrations if new to actives
