I've always struggled with my lips because they're cracked year round. I've tried multiple brands from EOS, carmex, Burt's Bees, Aquaphor, etc. and although they do help they don't prevent cracked lips. I even tried drinking more water and using lip products that contain SPF but, I still struggled with my cracked lips until I bought the Laneige Lip Sleeping Mask. I love this product, it keeps my lips moisturized and gently exfoliates them. I use it any time during the day when I feel that my lips lack moisture.
