Sunburned lips occur when the delicate skin on the mouth is exposed to excessive ultraviolet (UV) radiation from the sun, leading to inflammation. Symptoms include redness, swelling, tenderness, dryness, cracking, and peeling as the skin attempts to heal.
Effective Relief Options
Pure aloe vera gel soothes sunburned lips, possessing anti-inflammatory properties that reduce discomfort and support healing. Apply fresh gel directly from a plant or use a 100% pure, unscented product. Cool compresses also provide immediate relief; soak a soft cloth in cool water and gently hold it against the lips to alleviate burning and reduce swelling.
Moisturizing lip balms containing ingredients like soy, shea butter, or cocoa butter replenish moisture and protect healing skin. These ingredients create a gentle barrier that aids in recovery. For pain relief and to reduce swelling, over-the-counter anti-inflammatory medications such as ibuprofen or aspirin can be taken orally. Natural humectants like honey draw moisture into the skin and have antibacterial and anti-inflammatory qualities. Coconut oil, a good emollient, moisturizes and forms a protective barrier, reducing moisture loss.
What to Avoid
Certain ingredients in lip products can exacerbate irritation and should be avoided. Products containing camphor, menthol, or phenol are not recommended; while they may provide an initial cooling sensation, they can cause further drying and irritation. Similarly, alcohol, often listed as denatured ethanol or isopropyl alcohol, can strip moisture from the lips and compromise the skin barrier.
Strong fragrances, artificial colors, and parabens are also best avoided, as these can trigger allergic reactions or increase skin sensitivity. Petroleum jelly, commonly found in many lip balms, is not recommended for sunburned lips because its occlusive nature can trap heat, hindering cooling. Chemical sunscreens, such as oxybenzone, should also be avoided due to potential absorption and irritation.
When to Seek Help and Prevent Future Sunburns
While most cases of sunburned lips resolve with home care within three to five days, certain symptoms warrant medical attention. Consult a healthcare provider if you experience:
Severely swollen lips, a swollen tongue, or a rash.
Signs of infection, such as drainage, pus, a foul odor, or a fever of 100.4°F (38°C) or higher.
Difficulty eating, drinking, talking, or opening your mouth.
Symptoms that persist or worsen beyond the typical healing period.
Preventing future sunburns on the lips is important due to their thinness and lower melanin content, which makes them highly susceptible to UV damage. Apply a lip balm with an SPF of 30 or higher for effective prevention, providing protection against both UVA and UVB rays. Reapply frequently, especially after eating, drinking, or licking your lips, as the product wears off quickly. Seeking shade during peak sun hours (10 a.m. to 4 p.m.) and wearing a wide-brimmed hat can further shield the lips. Staying well-hydrated also contributes to overall lip health and resilience against sun damage.
