How It Works

Numbuzin No.3 Blue Bio-Retinol Pore Refining Serum uses a gentle bio-retinol complex with encapsulated retinol to help improve pore size, smooth uneven texture, and soften fine lines with less irritation than stronger retinoid formulas. Niacinamide helps regulate excess sebum and support brighter-looking skin, while salicylic acid helps clear clogged pores and reduce congestion. Barrier-supporting ingredients like panthenol and Centella help improve comfort and reduce dryness.
