Frequently asked questions
Can I use vitamin C with niacinamide?
Yes, most modern formulas combine well.
Does vitamin C replace SPF?
No. It complements daily sun protection but does not replace it.
Why has my serum changed colour?
Ascorbic acid oxidises in air and light. A slightly yellowed serum can still be used, but a brown one is better replaced.
