Frequently Asked Questions

Q: What does nicotinamide (niacinamide) do for the skin in this face serum?

A: Nicotinamide (also known as niacinamide or vitamin B3) is a well-researched skincare ingredient that helps even out skin tone, support the skin's natural moisture barrier, refine the appearance of pores, and smooth the look of fine lines. The JAYSUING Nicotinamide Face Serum delivers these benefits in a lightweight liquid essence that absorbs quickly without leaving a greasy residue.

Q: Is this nicotinamide serum suitable for sensitive skin?

A: Yes — this serum is formulated to be compatible with all skin types, including sensitive and mature skin. However, as with any new skincare product, we recommend performing a patch test on a small area of skin before full application, especially if your skin is particularly reactive.

Q: How long will one 30ml bottle of this face serum last?

A: With a typical application of 3–5 drops per use, one 30ml bottle should last approximately 4–6 weeks with once-daily use, or around 2–4 weeks with twice-daily use. The product should be used within 6 months of opening for optimal efficacy.

Q: Can I use this serum with other skincare products?

A: Absolutely. This niacinamide serum is designed to layer well within a multi-step routine. Apply it after cleansing and toning, then follow with your moisturiser and SPF in the morning. It pairs well with hydrating and brightening products.
