The Plum Niacinamide Face Serum with Rice Water is one of the brand's most popular, holy-grail skincare products. It is specifically formulated to tackle blemishes, acne marks, uneven skin tone, and large pores.

Plum offers this serum in two strengths: a 10% concentration (their bestseller for targeted action) and a 5% concentration (ideal for total beginners or highly sensitive skin). Both feature a unique, lightweight, milky-fluid texture that absorbs instantly without leaving any sticky residue.
