The Baby Lips Lip Balms tout themselves as being a clinical strength moisturizing lip balm with SPF 20 sunscreen and are supposed to provide 8 hour moisture along with lip renewal. After four weeks, your lips are supposed to be 82% visibly less dry, 94% less rough, 77% more supple, and 77% better looking. I haven't tested these balms for four weeks but I'll try to and update when I'm done with it
