Final Thoughts

Finding the right serum for oily skin doesn’t mean fighting your natural oils it means balancing them. Oily skin still needs hydration, just not in heavy, pore-clogging formulas. That’s why Korean skincare has become such a game changer: lightweight, fast-absorbing serums that keep shine under control while improving clarity and texture.

The five options we explored COSRX Niacinamide 15, Beauty of Joseon Calming Serum, Innisfree Green Tea Seed Serum, Some By Mi Miracle Serum, and Torriden Dive-In Serum cover every need an oily skin type may face. From oil control and pore refinement to calming irritation and restoring hydration, each one delivers targeted results without leaving the skin greasy.

If your priority is tighter pores and less shine, COSRX is your best bet. For calming breakouts, the Beauty of Joseon serum is a gentle favorite. If you’re after everyday hydration that feels refreshing, Innisfree’s classic green tea formula is perfect. For stubborn blackheads and uneven skin, Some By Mi offers a clarifying boost. And if you’re oily but also dehydrated, Torriden provides deep yet weightless hydration.

The best approach? Choose one that fits your main concern and stay consistent. With time, you’ll notice less shine, fewer breakouts, and an overall smoother, more balanced look. In 2025, these serums stand out as the top Korean skincare solutions for oily skin, proving that with the right routine, oily skin can look healthy, fresh, and naturally glowing.
