Expert Review Summary
The Some By Mi Yuja Niacin 30 Days Blemish Care Serum centers on 82% Citrus Junos extract and a clinical-level 10% niacinamide concentration. Yuja provides natural vitamin C, citric acid, and antioxidants, while niacinamide targets sebum production, pore visibility, and melanin transfer behind post-acne marks. Glutathione, arbutin, 12 vitamins, and a brightening botanical complex including mulberry and licorice reinforce the pigment-fading effect.
The texture is a lightweight pale-yellow gel-serum that absorbs within seconds without residue, compatible with AM and PM routines. At $19 for 50ml the cost-per-ml is low for a double-active brightening serum. Citrus-derived fragrance means fragrance-sensitive users should patch test first.
