Vitamin C + Niacinamide: Are They Compatible?

No label conflict found

Information from the FDA label and published sources. Not medical advice.

Why

The 'pure Vitamin C neutralizes niacinamide' myth comes from 1960s-era lab conditions at high heat. In modern cosmetic formulations at skin pH, Vitamin C and niacinamide coexist perfectly. Many professional serums deliberately combine both.

Usage guidance

Apply Vitamin C first (ideally AM), niacinamide second. Or split — Vitamin C AM, niacinamide PM — no efficacy lost.
