Depends on the cause: dark spots can be caused by many different things. If you have dry cracking lips, using moisturizer and sunblock can make the dark spots lighter and may go away. Home remedies like lemon juice used on your lips may help. Smoking can cause skin changes and should be stopped. But it could also be a skin cancer. If the dark spots persist, you should have a doctor look at your lips
