Purchased last year, the serum is about half used. The retinol ampoule is about 1/3 used. The product felt good! I am selling because I purchased something else. Recommended for those who are hesitant to buy! Please give it a try. This is a set of serum and ampoule that smooths skin texture and minimizes pores. - Product Name: numbuzin SERUM - Product Type: Serum - Product Name: Pore RESET - Product Type: Ampoule Thank you for viewing.
