What Niacinamide Does for Your Skin

Pore Minimizing — Niacinamide regulates sebum production at the skin surface level, which visibly reduces the appearance of enlarged pores over time. Studies show consistent daily use at 10% concentration produces measurable improvements in pore size within 4–8 weeks.*

Skin Tone Evening & Blemish Reduction — Niacinamide inhibits the transfer of melanin to skin cells, reducing dark spots, hyperpigmentation, and post-acne marks. One of the most well-researched ingredients for uneven skin tone — without the irritation of retinol or acids.*

Skin Barrier Strengthening — Niacinamide stimulates ceramide synthesis in the skin, rebuilding the protective lipid barrier that keeps moisture in and environmental aggressors out. Essential for sensitive skin and those with compromised barrier function.*

Oil Control Without Stripping — Unlike alcohol-based toners or harsh astringents, 10% niacinamide regulates sebum production without disrupting the skin's natural moisture balance. Suitable for oily, combination, and even dry skin types.*

Fine Line Smoothing — Niacinamide supports collagen production and improves skin elasticity over time, visibly reducing the appearance of fine lines with consistent use.*

How to Use

Who This Is For

Anyone dealing with enlarged pores, uneven skin tone, oily or combination skin, or post-acne marks. Niacinamide is one of the most versatile and well-tolerated skincare actives — it works across all skin types and ethnicities, and it pairs well with almost every other skincare ingredient including retinol, vitamin C, and AHAs.*

Frequently Asked Questions

How long until I see results?
Most people notice reduced oiliness and improved skin texture within 2 weeks. Pore minimizing and skin tone improvements are typically visible at the 4–8 week mark with consistent twice-daily use.*

Can I use this with vitamin C?
Yes. The old concern about niacinamide and vitamin C forming niacin (which causes flushing) has been largely debunked at the concentrations used in skincare. You can layer them, or use vitamin C in the morning and niacinamide at night if you prefer.*

Is 10% too strong for sensitive skin?
10% is the research-backed concentration for visible results. Most people tolerate it well. If you have very sensitive skin, patch test first and start with once-daily use before moving to twice daily.*

Can men use this?
Absolutely. Niacinamide is equally effective for men's skin — particularly for controlling shine, minimizing post-shave irritation, and reducing enlarged pores common with thicker skin.*
