I've struggled with chapped, dry lips ever since I was a child. I finally heard about this thing called 'Korean sincare" earlier this year and got the rest of my dry skin in order, but my lips just would not budge even with newfound religious application of my favorite chapstick. I heard from several skincare forums that this product is an absolute miracle, and with nothing left to lose I tried it. It WORKS. You have to definitely apply a nice, generous amount so when you go to bed your lips will feel sticky and tacky and if you have long hair like me expect to get some strands caught in it every now and then. I roll around a lot so I'm sure some of the product comes off onto my pillow or face but I still saw night and day improvement. I still have to apply chapstick because I am just so naturally dry everywhere but now I only have to apply chapstick 2 - 3 times a day instead up upwards of 10+ times a day before (and that never did anything). This product SAVED my lips, my lips commonly split on the bottom lip or at the corners of my mouth and ever since I started using it my lips no longer split or crack. I am so grateful to this product. It is worth it!
