Purchase date: August 15, 2025. Opened and used twice (4 drops with dropper x 2 times), but it didn't agree with my skin, so I'm selling it. The box has been disposed of, so only the main product will be included. I will pack it securely with cushioning material for shipping. The remaining amount is as shown in the photos. Since it has been opened, I will sell it for half price. Thank you for your understanding. This serum contains niacinamide and arbutin to even out skin tone. - Brand: anua - Product Name: Niacinamide 10+ Arbutin 2 - Contents: 30ml - Features: Serum - Usage: Skincare - Type: Mild Retail price: 2,800 yen Thank you for looking.
