This set of three serums is perfect for skincare. They are almost unused, and I'm selling them because they unfortunately didn't suit my skin at all. I've used each one about five times or less. I've also been careful not to touch the dropper parts. Products included: * Medicube PDRN Pink Ampoule * Medicube Azelaic Acid 16BB Calming Serum * Medicube PDRN Pink Exosome Shot 7500 - Brand: medicube - Color: Pink - Color: Blue - Number of Items: Set of 3 - Type: Serum Thank you for looking.
