Niacinamide, also known as vitamin B3, is one of those gold-standard ingredients I come back to time and again in clinic—and for good reason. It’s remarkably well-tolerated, making it suitable for virtually every skin type, including sensitive, redness-prone and acne-prone skin, and it delivers a wide range of benefits that support healthier, more resilient skin.

FAQs
What is Niacinamide?
Niacinamide is a water-soluble form of vitamin B3 that's renowned for its versatility and gentle effectiveness.
What Does Niacinamide Do?
It helps to strengthen the skin barrier, which is crucial if you’re dealing with sensitivity, redness, or dehydration. It increases the skin’s natural production of ceramides—the lipids that keep your barrier intact and your skin feeling calm and comfortable.
It’s also brilliant for regulating oil production and the appearance of large pores, which is why I often recommend it for those prone to congestion or shine, particularly in the T-zone. At the same time, niacinamide has an impressive ability to brighten uneven skin tone, making it a hero ingredient if pigmentation or dullness is a concern. It inhibits the transfer of melanin from pigment cells to the skin surface, helping to fade dark marks over time.
Niacinamide has been shown to reduce inflammation and support the skin’s natural repair processes, which is why it often finds its way into routines designed to tackle breakouts, redness, or even early signs of aging.
In short, it’s a gentle powerhouse. If I had to choose one ingredient that plays nicely in almost any skincare routine—whether you’re targeting blemishes, sensitivity, or pigmentation—it would be niacinamide. Consistent use, ideally in a well-formulated serum or moisturiser, can make a tangible difference to the clarity, calmness, and overall health of your skin.
When Should You Use Niacinamide?
Niacinamide works beautifully in both your morning and evening routines, making it ideal for leave-on products like our Flawless Moisturiser. For optimal results, use niacinamide twice daily - consistency is key to achieving the balanced, clear complexion it can deliver.
Can Niacinamide Be Used with Other Ingredients?
Niacinamide is one of skincare's most sociable ingredients. It pairs excellently with hyaluronic acid for enhanced hydration, works synergistically with retinoids for comprehensive anti-aging benefits, and can even help your skin tolerate stronger actives more effectively.
How Long Does Niacinamide Take to Work?
With twice-daily application, improvements in skin texture and tone typically become noticeable within 2-3 weeks. However, the full benefits of niacinamide - including pore appearance and redness reduction - develop over 8-12 weeks of consistent use.
