I wasn't too sure about this sleeping pack when I first got it (plus the size of the container is much smaller than I had imagined) however a little goes a long way! But too much and you'll find it pretty greasy and unpleasant. This mask is light enough to use during dry windy winter days especially if you need an extra layer of protection! Not sure if i'll re-buy as I definitely want to try COSRx's honey sleeping pack first and well as Makonde's jasmine and rose sleeping packs.. >_<
