Best K-Beauty Serums for Combination Skin
120 serums reviewed and ranked for combination skin. Updated 2026.
Combination skin gets the most out of targeted serum application — use oil-regulating actives on the T-zone and hydrating formulas on dry areas, or find a balanced serum that addresses both. Niacinamide is the MVP ingredient here because it simultaneously controls oil and strengthens dry zones.
What to Look For
- ✓ Versatile formula that addresses both oil and dryness
- ✓ Lightweight enough for the T-zone, nourishing enough for cheeks
- ✓ Can be spot-applied at different concentrations per zone
Key Ingredients
- Niacinamide — Balances oil and hydration — the ideal combo-skin ingredient
- Hyaluronic Acid — Provides zone-appropriate hydration without adding oil
- Vitamin C — Brightens uneven tone across different skin zones

9/10 · serumBeta Glucan Power Moisture Serum
iUNIK signature product and one of the best-kept secrets in sensitive-skin K-beauty. 70% beta-glucan — a powerhouse humectant and soothing agent — combined with a minimalist supporting cast. The result is a serum that hydrates like hyaluronic acid but also calms reactive skin the way centella does. Cult favorite for a reason.
