It's great to make and use ampoule pads.

At first, I used to buy and use ampoule pads. However, they were too expensive, so I now buy the pads sold separately, soak them generously in ampoule, and use them as a face mask. They are so good that I don't need to buy mask packs separately. You can gather up ampoules you don't use often or samples you received, soak them in pads, and keep them refrigerated. Just store them in the refrigerator and use them as needed.
