Niacinamide serums are not all built the same way. In some, niacinamide is the main active. In others, it supports a different ingredient instead.
All five serums here are sold on Nykaa. Four use niacinamide at 10% as the main active: The Ordinary, Plum, Minimalist, and The Derma Co. One is from Dot & Key, using niacinamide at 5%. Its core is a 10% Vitamin C and Vitamin E combination.
Niacinamide is a water-soluble form of vitamin B3. It is widely used in serums to support skin’s barrier function. It also helps with oil and uneven tone. Review counts below show purchase and review volume only. They do not show fit or quality for your skin.

- Plum 10% Niacinamide Brightening Face Serum with Rice Water adds rice water to its niacinamide base. Rice water is a traditional ingredient used as a mild, soothing addition alongside active ingredients. Plum positions this serum for brightening. It has 144,181 reviews.

- The Derma Co 10% Niacinamide Face Serum For Acne Marks is formulated for acne marks, not general brightening. It has 74,640 reviews.
- Dot & Key 10% Vitamin C + E Face Serum With 5% Niacinamide builds around Vitamin C and Vitamin E. Niacinamide is added as a supporting ingredient, not the main active.
