Sunday Riley B3 Nice 10% Niacinamide Serum
Links may contain affiliate codes.
Formulation Summary
A premium 10% niacinamide serum built around antioxidant-rich botanicals. The formula pairs standard niacinamide with trans-resveratrol and EGCG from green tea for free radical protection. Brightenyl, a biotechnology-derived brightening agent, rounds out the active complex.
Sunday Riley positions this as a multi-tasking antioxidant treatment rather than a pure niacinamide serum. The botanical extracts include turmeric, centella, boswellia, and neem. These add anti-inflammatory properties but also increase the formula's complexity. The water-based texture absorbs quickly without residue. Contains less than 1% synthetic fragrance.

The Formulation Explained
Antioxidant-forward approach
Sunday Riley positions this as a multi-tasking antioxidant treatment rather than a pure niacinamide serum. Trans-resveratrol and EGCG from green tea provide free radical protection. Brightenyl, a biotechnology-derived ingredient activated by the skin microbiome, addresses dark spots through a different mechanism than niacinamide alone.
Complex botanical formula
The formula includes turmeric, centella, boswellia, neem, and other botanical extracts. These add anti-inflammatory and soothing properties but also make this a more complex formula. Users with botanical sensitivities may want to patch test.
10% niacinamide concentration
Niacinamide appears second in the INCI list after water, consistent with the 10% claim. This is a standard effective concentration for oil control, pore minimizing, and brightening benefits.
Contains fragrance
Unlike many niacinamide serums, this formula includes synthetic fragrance at less than 1%. The brand is transparent about this. If you're sensitive to fragrance, this may not be the right choice.
