Niacinamide (vitamin B3) is a multifunctional skincare active that helps strengthen the skin barrier, regulate sebum, reduce hyperpigmentation, and improve uneven tone and texture. At 10% it is a high concentration commonly used for visible cosmetic benefits.
| Reported effect | How often | Notes |
|---|---|---|
Mild transient flushing or warmth | Uncommon | More associated with oral niacin than topical niacinamide, but occasionally reported with topical use. |
Stinging, burning, or tingling on application | Uncommon | More likely at higher concentrations like 10% and on compromised or sensitive skin. |
Redness or irritation | Uncommon | Can occur with frequent use or when combined with other actives; usually resolves with reduced frequency. |
Dryness or peeling | Rare | Occasionally noted, often linked to other ingredients in the formulation. |
Allergic contact dermatitis | Very rare | Isolated case reports; true sensitization to niacinamide is uncommon. |
