Best Serums for Oily Skin

If you have oily skin, the best Korean serums are usually the ones that control shine without drying you out. The goal is lightweight hydration + calming ingredients + oil-balancing actives, so your skin stays smooth and clear instead of greasy by midday. Korean skincare does this so well because most formulas feel thin, absorb fast, and layer perfectly under sunscreen and makeup.

COSRX 15% Niacinamide Serum

One of the top picks for oily skin is COSRX 15% Niacinamide Serum. Niacinamide is famous for helping reduce excess oil, the look of pores, and post-acne marks, and COSRX pairs it with Zinc PCA which is also great for oily and breakout-prone skin. This serum is especially good if you want that “cleaner pores, less shine” look over time.

Beauty of Joseon Glow Serum (Propolis + Niacinamide)

If you want something that gives glow but still works for oily skin, Beauty of Joseon Glow Serum (Propolis + Niacinamide) is a super popular choice. Propolis is known for being soothing and supportive for stressed skin, while niacinamide helps balance oil and improve uneven texture. It’s the kind of serum that makes your skin look healthy and “glass skin” without feeling heavy.

Anua Heartleaf 80 Soothing Ampoule

Another amazing option (especially if your oily skin gets clogged easily) is the Anua Heartleaf 80 Soothing Ampoule. Heartleaf is a favorite ingredient in Korea for calming breakouts and reducing irritation, and this ampoule is known for being non-greasy and lightweight, so it won’t feel sticky on oily skin.

Torriden DIVE-IN Low Molecular Hyaluronic Acid Serum

If your oily skin gets dehydrated easily (tight but still shiny), Torriden DIVE-IN Hyaluronic Acid Serum is a perfect lightweight option. It hydrates without feeling oily or heavy, and it helps your skin look smoother and healthier without adding extra shine.

In the end, these serums are some of the best Korean choices for oily skin because they all feel lightweight, non-greasy, and effective without making your face look shiny or heavy. Whether you want oil control, calming care, or hydration that doesn’t clog pores, each one of these options can fit perfectly into a simple routine.
