This is a set of Hadakirara's all-in-one serum and a spot treatment serum. The spot treatment description is quoted from the official website below: This "Hadakirara Pinpoint" contains a high concentration (so high it can't fully dissolve) of vitamin C derivative (APPS), which is effective enough to kill acne bacteria, making it very effective for red acne. In addition to its effects on acne, the high concentration of vitamin C derivative (APPS) can also be expected to improve pores and control sebum secretion. Both products were purchased about six months ago. They have been stored in the refrigerator. - Brand: Hadakirara - Product Name: Serum Thank you for looking.
