Practice good lip hygiene and use medicated lip balms sparingly. Be cautious of lip balms that contain camphor and menthol, which both provide a tingly feeling that some people can't get enough of [source: Janes].
Moisturizing Extremely Dry Lips
You don't need pricey formulas to fix extremely dry lips. In fact, you can probably get the job done after a quick look through your kitchen cupboard or bathroom cabinet.
Exfoliation isn't just good for your body -- it also can help your lips. To exfoliate, gently rub your lips with a washcloth morning and night. Mix together a small amount of olive oil and sugar, and then rub the concoction on your lips. If you'd rather not go the natural route, head to your drug store and look for a lip exfoliator.
Once you've exfoliated, follow up by applying a lip balm or lip treatment. Products with beeswax, shea butter, vitamin E or oils such as jojoba, olive and coconut can provide your lips with an adequate amount of hydration [source: Latona]. Reapply your lip balm often. Inexpensive petroleum jelly can also work as a lip moisturizer. However, save it for times when the sun is starting to set, or use a lip product with sunscreen on top of it. Lip products should have a sun protection factor (SPF) of at least 15. Also make sure that your lip balm's SPF offers broad-spectrum coverage from both UVA and UVB rays.
Sunscreen is vitally important for your lips. Remember, your lips don't have melanin (pigment). That means that they are extremely susceptible to the sun's damaging rays, which can cause skin cancer. Sunburned lips can be uncomfortably dry, and in some cases they'll also peel. Finally, if you want to keep the signs of aging at bay, sunscreen can reduce any wrinkles or cracks in skin.
