What Is Niacinamide (Vitamin B3)?
Niacinamide is the topically active form of vitamin B3; it is effective for pore tightening, strengthening the moisture barrier, reducing hyperpigmentation, and regulating sebum production. Concentrations of 5–10% are most common; it is also well-tolerated by sensitive skin types.
What Does Niacinamide Do?
Niacinamide works to control pore size and sebum output, even out skin tone, and reduce fine lines and redness. It can be used alongside vitamin C and retinol; typically, niacinamide is applied first, followed by vitamin C or retinol. Routine recommendations can be found in our vitamin C serum and retinol guides.
Who Should Use Niacinamide?
It is especially beneficial for oily, combination, and acne-prone skin. It also has a soothing effect on sensitive and rosacea-prone skin. You can plan your application sequence with our skincare routine guide.
Niacinamide at concentrations above 10% may cause mild redness in sensitive skin; starting with a lower percentage and gradually increasing is a safer approach. When used with retinol in an evening routine, applying niacinamide first followed by retinol can help reduce irritation. Consistent use for at least 8–12 weeks is required to see results for hyperpigmentation and pore refinement.
