Best Serum for Large Pores and Oily Skin: What Actually Works

Final Takeaway

The best serum for large pores and oily skin isn’t about harsh exfoliation—it’s about balance. Oil regulation, barrier support, and antioxidant protection work together to visibly refine pores and smooth skin texture.

When chosen correctly, serums like niacinamide and arginine don’t just mask pores—they improve the skin conditions that make them look enlarged in the first place.
