Sunburned lips occur when the delicate skin on your lips is exposed to ultraviolet (UV) radiation. This damages skin cells, leading to inflammation. Symptoms include reddening, swelling, tenderness, and sometimes blistering. Lips are particularly susceptible because their skin is thin and contains minimal melanin, the natural pigment that helps protect against UV rays.
Immediate Relief and Healing Strategies
Applying a cool compress can reduce pain and inflammation. Soak a clean cloth in cool water, wring it out, and gently hold it against your lips for several minutes.
Moisturizing the lips is important for healing. Use fragrance-free and dye-free lip balms, petroleum jelly, or products with aloe vera, shea butter, or vitamin E. These ingredients help hydrate the skin and create a protective barrier, preventing further moisture loss. If using aloe vera, choose a 100% pure product to avoid irritation.
Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help manage pain and reduce swelling. Staying well-hydrated by drinking plenty of water supports overall skin health and can help counteract dehydration.
Practices to Avoid During Healing
Resist the urge to pick or peel any flaking skin or blisters. Doing so can increase the risk of infection and cause further damage.
Avoid irritating products like flavored lip balms, or those with menthol, camphor, alcohol, or harsh chemicals. These ingredients can cause stinging, dryness, and prolonged discomfort. Also, refrain from consuming hot or spicy foods and drinks, as they can irritate the sensitive, healing lip tissue.
Avoid further sun exposure. Continued UV radiation can worsen the burn and prolong healing. Protect the area by staying indoors or seeking shade.
Preventing Future Sunburn on Lips
Regularly apply a lip balm with an SPF of 30 or higher. This protects against both UVA and UVB rays, which can cause damage.
Reapplication of SPF lip balm is important, especially after eating, drinking, or licking your lips, as these activities can quickly remove the protective layer. Reapplying every hour ensures consistent protection. Wearing a wide-brimmed hat provides additional physical shade for your lips and face.
Limit overall sun exposure, particularly during peak hours between 10 AM and 4 PM when UV radiation is strongest. Lips can burn in any season, and reflective surfaces like snow or water intensify UV exposure. Consistent year-round protection is important for lip health.
When to Seek Medical Attention
While most cases of sunburned lips heal within three to five days with home care, certain symptoms warrant medical attention. Seek professional help if you experience severe swelling or large, persistent blisters, as these can indicate a more severe burn or an allergic reaction.
Look for signs of infection, such as increasing pain, pus, red streaks, or a fever. Consult a healthcare provider if pain or discomfort does not improve within a few days, or if symptoms worsen. Any open sores or cracks on the lips that are not healing should be evaluated by a doctor.
