Hi, Thank you for your interest in GOSIV products. The repairing Retinol (Vitamin A) Night Serum, with its active ingredients such as 1% Retinol, Niacinamide and Ceramide, can help reduce the appearance of pores.

However, it may take time to reduce the appearance of pores, and the product begins to show its effect when used regularly.
