I actually got this because of its AHA properties. I'm not sure if it's working because of the AHA ingredient, or if it's just a good product in general. It's very similar to the Laneige sleeping lip mask, except it's a tiny bit thinner on the lips. Not as sticky. I especially love the scent. It's a relaxing herbal tea scent that I just can't get enough of. I use it the same way as the Laneige one. I put it on before bed time and wake up with super soft kissable lips!!! Would repurchase and definitely recommend!
