Promising review: "I love, love, love this product! Before I purchased it, I tried everything. I spent one winter in Chicago, and for years, my lips could never truly recover from the harsh, dry cold weather. Other products offered temporary moisture, but never had a lasting effect. I put this on at night and left it on as I slept. In the morning, after my normal cleanse routine, my lips were much softer. After three days of this use, I had normal, moist, soft lips. Now, for maintenance, I apply it once a week at night, alongside my facial mask routine, and my lips have never felt healthier. Pricey, yes. But you really only need a small amount, and it works fantastically. It is well worth the cost!" —Gwillickers
