A lifesaver during the winter! My lips can get very dry under colder conditions, but all I need to do is lather this stuff on my lips and let it sit overnight. The next morning, when you wipe it off, your lips are smooth and plump again! Lipstick can glide back on easily. However, I wouldn’t say this provides long-term moisture, it’s a rather a daily commitment to keep the top layer of your lips moist. I don’t mind this though.
