We ranked 10 Korean serums for pores & oil by the same three axes shown on every product page — evidence grade, cross-retailer rating consistency, and Korean market signal — with no sponsored slots. 4 carry our top "A" evidence grade. The formulas lean on Niacinamide 10%, Tranexamic acid 4%, Heartleaf, Tea tree. 7 of 10 are stocked in the US; the rest ship from Korea with duties already included in the price you see. Our current top pick is Anua Niacinamide 10% + TXA 4% Dark Spot Serum. Prices run $17–$38. Take the quiz to re-rank for your skin.










Right now we rank Anua Niacinamide 10% + TXA 4% Dark Spot Serum first for pores & oil, scored on evidence grade, rating consistency and Korean market rank rather than sponsorship. It's one of 10 options on this page — take the 60-second quiz to re-rank all of them for your own skin type and tone.
Each product is scored on published-evidence grade (4 here earn an "A"), how consistent its ratings are across retailers, and where it sits on Korean category charts. Nothing here is a paid placement — mallang doesn't sell products.
7 of the 10 are available from US retailers. The others ship from Korea; every price on this page already includes estimated import duties so the total is what you'd actually pay.
2 of the 10 carry our fungal-acne-safe flag, and 8 are fragrance-free. These flags are seed data pending human verification before launch — check each product page for its full flag set.
4 of the 10 appear on Korean retail category rankings, which is one of the signals we weight — Korea often adopts a formula months before it trends in the US.
