Thank you for viewing. The AGE-R BOOSTER is a skincare device designed to improve skin firmness. AGE-R BOOSTER medicube AGE-R BOOSTER-H Purchased from the official Medicube store. Used a few times, but I am selling it because I am using another facial device. There are minor scratches, but they are mostly unnoticeable. There are no instructions. I am looking forward to purchases from those who understand that this item has been in someone else's possession. Please refrain from purchasing if you are sensitive to such matters. Please refrain from price negotiations.
