I feel like it improves the application of foundation when used before makeup. Also for night care. The back of the lid is a dropper, so it can always be used hygienically. The photos from the third image onwards are of the ones I am currently using; the item for sale is the new, unopened one in the first and second images. November 2024 regular delivery. I can't use it all, so I'm offering it to someone who wants to try it.
