It is difficult to tell form the picture alone what is going on with your cat's lips unfortunately. It almost looks like she/he has a sore or even infection in her/his whiskers and commissure of the mouth. I would recommend you take your cat to your vet for an exam. She/he may need antibiotics to resolve this and possibly pain medication is she/he is is uncomfortable. I would also be concerned there may be sores in the mouth that need to be addressed if you are seeing them along the outside. It is possible your cat licked something toxic or caustic causing these problems. I would look around your home to see if there is anything she/he could have gotten in to. I hope your cat improves quickly!
