1. Can niacinamide be used every day?

Yes, niacinamide is generally safe for daily use. Most dermatologists recommend applying it once or twice a day depending on the formulation and skin tolerance, as it helps strengthen the skin barrier and maintain hydration.

2. How long does niacinamide take to show results on skin?

Like most skincare ingredients, niacinamide doesn’t deliver instant results. With consistent use, you may start noticing improvements in skin texture and hydration within a few weeks, while more visible changes typically appear within 4 - 12 weeks. Though, there’s no fixed timeline.

3. Does niacinamide help with acne-prone skin?

Niacinamide may help support acne-prone skin by regulating excess sebum, reducing inflammation, and strengthening the skin barrier. These properties can help minimise breakouts and improve the overall appearance of the skin over time.

4. Can niacinamide cause skin irritation?

Niacinamide is generally well tolerated by most skin types, including sensitive skin. However, very high concentrations may cause mild irritation for some individuals, so patch testing and starting with lower concentrations is recommended.

5. Can niacinamide be used with vitamin C?

Yes, niacinamide can typically be used with vitamin C in a skincare routine. Modern formulations stabilise both ingredients, allowing them to work together to support brighter, healthier-looking skin without reducing effectiveness.
