Niacinamide, also known as vitamin B3, is a powerhouse ingredient in skincare, celebrated for its ability to improve elasticity, reduce fine lines, even out skin tone, and calm redness. It is well-tolerated by most skin types and pairs seamlessly with other active ingredients. However, choosing the right serum can be overwhelming given the abundance of options. To help, we consulted two leading dermatologists: Dr Ketaki Bhate, consultant dermatologist at Kensington Dermatology Clinic, No23. Skin, and Dr Aiza Jamil, consultant dermatologist at sk:n in Manchester. They share their top picks and answer common questions about niacinamide.

Expert Answers to Common Niacinamide Questions
What is niacinamide and how does it benefit skin?
Dr Bhate explains that niacinamide is a form of vitamin B3 with strong evidence supporting its use. It strengthens the skin barrier, reduces redness and inflammation, balances oil production, improves uneven skin tone, and can help with anti-ageing when used consistently.
Is niacinamide suitable for all skin types?
Dr Jamil notes that niacinamide is generally well-tolerated, but those with very sensitive or rosacea-prone skin should avoid concentrations over 10% to prevent flare-ups. People with compromised skin barriers from over-exfoliation or retinoid use should also pause use until the barrier is repaired.
How soon can results be seen?
Within two weeks, skin may feel less tight and irritated. After three to four weeks, oil production regulates, reducing shine and breakouts. Long-lasting improvements in pigmentation and texture may take up to eight weeks.
Tips for incorporating niacinamide into a routine
Avoid layering with AHA/BHA acids if you have sensitive skin. Use a gentle cleanser and moisturiser, and always apply sunscreen to prevent pigmentation. Choose fragrance-free formulas for better tolerance.
