This ampoule is so affordable for the price and the size! I saw celebs raving about this on some makeup shows and was curious to try it and it is perfect for my dry skin! I apply it at night and even during the day before my makeup and do not have to worry about using so much since ampoules can be pricey! I would definitely order again once I run out, but I don't know when that would be since it is so much quantity!
