Can you use vitamin C with niacinamide?
Yes — the cancellation myth is decades out of date. Niacinamide and vitamin C are an excellent brightening pairing, layered or in one product.
Why
The 'they cancel each other out' rumour comes from a 1960s test-tube study using raw ingredients under heat — conditions that don't apply to modern formulations or skin temperature. Both ingredients fully retain their efficacy when layered.
How to layer them
Apply vitamin C first (it needs direct contact at its lower pH), wait 30-60 seconds, then niacinamide. Standard placement is morning. Many products combine both — CeraVe Vitamin C Serum, Olay Regenerist Vitamin C + Peptide 24, La Roche-Posay Pure Vitamin C10 all do.
Pro tip
This pairing attacks hyperpigmentation through two different mechanisms (vitamin C blocks production, niacinamide blocks transfer) — better than either alone.
