COSRX Lip Sleep Ceramide Lip Butter Sleeping Mask 18 ingredients
I stumbled across this product by accident but it has solidified my belief in lip masks. This is my favorite by far. It has staying power and allows me to go to bed and wake up with soft lips. I literally look forward to using this mask at the end of my night time routine.
I swear by this lip mask. I suffered from extremely dry lips for months including most of the summer. Alongside prescribed cream and aquaphor this has brought my lips back. I use it in the morning and night almost like a moisturizer for my lips. I was looking at Laniege however I feel like it’s mainly just marketed better.

Works great. But not vegan or cruelty-free!
