Mung Bean Pore Tight-Up Serum — Reddit Reviews
by beplain
Updated November 10, 2026
Pore-blurring niacinamide serum with a light, makeup-friendly finish; cooling is underwhelming.
What the community says
Redditors mainly reach for this lightweight serum when pores look obvious, and one oily-skin user says it sits well under makeup. The trade-off is a cooling effect some users barely notice, making the summer-refresh claim YMMV.

What the science says
Niacinamide has some evidence for helping acne, often working about as well as a common acne antibiotic applied to the skin 1. For dark spots, niacinamide has some evidence of fading patches, and all four studies that tested it directly found it helped more than a moisturizer without it 2. It also has some evidence for signs of aging, with studies showing firmer skin and fewer wrinkles 3. Its effect on the skin barrier is not proven yet, since only one study tested it directly and found less water loss 4.
