I bought this product on a friend's recommendation, and I would highly recommend it to anyone who's interested in buying it! I've only been using it for a few days but I've already noticed a huge difference in the softness of my lips. I've had issues with chapped lips for a long time now, since I accidentally used a chapstick that had ingredients I was allergic to a while ago, but this mask has completely cured that! My only complaint would be that since I sleep with it on, it does get on my pillowcase, but for how good of a job it does moisturizing my lips, I would say it's worth it. It's a 10/10 product for me, and I would definitely repurchase it (if I ever need to! You get a ton of product, and I don't think I'll be running out soon, regardless of the fact that I use it every night).
