Real reviews from verified buyers
This serum completely transformed my skin! My acne has reduced so much and my dark spots are fading faster than anything I’ve tried before. The texture is super lightweight and doesn’t feel greasy at all.
I’ve struggled with oily, acne-prone skin for years, but this actually works. My skin looks less shiny, pores appear smaller, and breakouts are much more under control.
After about a week, I could already see a difference. My redness calmed down and active pimples started shrinking. It’s gentle but still very effective.
I love how lightweight this serum is. It absorbs instantly and layers perfectly under sunscreen. My skin feels smoother, clearer, and more balanced.
This is the first niacinamide serum that actually helped with my acne marks. My skin tone looks more even and the overall texture has improved a lot.
I was worried 12% might be too strong, but it’s surprisingly gentle. My breakouts are less frequent, and my skin looks brighter and healthier overall.

Everything you need to know about our niacinamide serum
Niacinamide (Vitamin B3) is a water-soluble vitamin that works at the cellular level to improve multiple skin concerns. It helps strengthen the skin barrier, regulate oil production, reduce inflammation, and inhibit melanin transfer—resulting in clearer, brighter, and more balanced skin.
Yes! Niacinamide is compatible with most active ingredients, including vitamin C, retinol, AHAs, and BHAs. However, we recommend introducing one active at a time and monitoring your skin's response. Always patch test when combining new products.
Most users notice improvements within 2-4 weeks of consistent use. For optimal results, use twice daily as part of your morning and evening routine. Maximum benefits are typically seen after 8-12 weeks of continuous use.
Yes! Our formula is specifically designed to be gentle and non-irritating, even at 12% concentration. It's dermatologist-tested and suitable for sensitive skin. However, if you have extremely reactive skin, we recommend starting with once-daily application and gradually increasing.
While niacinamide is generally considered safe during pregnancy and nursing, we always recommend consulting with your healthcare provider before starting any new skincare products during this time.
No, our serum is completely fragrance-free to minimize the risk of irritation. The only scent you'll notice is the natural, mild smell of the active ingredients.
Try Fuzast® risk-free. If you're not satisfied with your results within 60 days, we'll refund your purchase. No questions asked. That's how confident we are in our formula.
