Slightly acidic — close to skin's natural pH (4.5–5.5). Gentle and generally well tolerated.
Dermatologist Note
10% niacinamide is at the higher end of studied concentrations. A 2021 meta-analysis confirmed niacinamide reduces hyperpigmentation comparably to hydroquinone with fewer side effects. The zinc PCA component helps regulate sebum. Note: flushing (redness/tingling) can occur at high concentrations in some individuals — start with every other day use.
