Used. To make the remaining amount easier to see, I pushed the product down from the top, so the packaging got dirty (tears). Opened in August 2024! I'm sorry, I don't remember the exact date (＞人＜;) I haven't used it for even 10 days since then, so I think there's almost the full amount left. I would appreciate it if someone understands the condition. 【Product Overview】 COSRX's "The Retinol 0.1" is a face cream designed to improve skin firmness and smoothness.
