How to Treat Sun Blisters on Lips

After a long day in the sun, you may discover you have sunburn — even if you took precautions to protect your skin. While you may see redness or a rash or feel the tenderness of your skin right away, blisters may take a bit longer to appear. Normally, blisters occur within a few hours of the burn, but they can develop days after excessive sun exposure [source: Livestrong].

Blisters can range in size based on the severity of your burn. They can also be quite painful, especially on a sensitive area like your lips. Because you're constantly using your mouth, these blisters may be even more irritating and painful when they appear on the lips. As a result, your first order of business may be soothing your discomfort instead of treating your blisters.

Any type of burn will cause inflammation of the skin, which contributes to the pain the burn causes. Taking aspirin, acetaminophen or ibuprofen can help reduce this inflammation and ease some of the discomfort that follows [source: Nissl].

Cooling gels, which often contain soothing aloe vera, corticosteroids or antihistamines, can also be applied to sunburned lips to ease pain and moisturize damaged skin [source: WebMD].

You also should try to reduce pain by avoiding further irritation of your sunburned lips and blisters. Try to limit your sun exposure until the blisters have healed, because further sun damage can lead to more pain. Keep the area dry, cool and free from any possible irritants — including contact with the blisters [source: Nissl].

Once you have eased some of the pain of your blisters, read on to find several steps you can take at home to help the healing process.

After you've taken preliminary steps to ease the pain of sunburn and the sun blisters that come with them, you can try some home remedies designed to help yourself heal. A basic sun blister should heal on its own, but you can hasten the process.

If the blisters are small and unbroken, don't try to pop them. This won't help the healing process and may lead to infection. Although you can drain larger blisters with a clean needle, you shouldn't because the skin around your lips is incredibly sensitive. Do all you can to help keep the blisters and the skin covering them intact, as this will protect the sensitive new skin underneath from infection [source: Nissl].

Cleaning the blisters regularly and applying an antibiotic ointment, like polymixin or bacitracin, will help to prevent infection, which will help them heal properly and quickly [source: Nissl]. Because the blisters are on your lip, you won't be able to cover them with a bandage. This makes cleanliness of utmost importance; your lips will touch many potentially irritating substances throughout the day.

While these home remedies will help you with your blisters, there are other so-called remedies that you shouldn't use; they'll do more harm than good. Avoid petroleum-based products, as well as any lotions that contain benzocaine or lidocaine [source: MedlinePlus].
