What causes redness and a burning sensation above the lips?

Generally, redness and a burning sensation above the upper lip may be caused by dry weather, dietary irritation, or conditions such as cheilitis, contact dermatitis, and perioral dermatitis. When these symptoms occur, it is advisable to seek medical attention promptly to identify the underlying cause and receive targeted treatment. Specific causes are analyzed as follows:

1. Dry weather: In dry climates, the skin on the lips loses moisture quickly. If hydration is not replenished in time and proper moisturizing measures are not taken, the skin above the lips can become dry, red, and develop a burning sensation due to dehydration. Applying lip balm to the area above the lips and maintaining skin moisture, along with increasing daily water intake, can help.

2. Dietary irritation: Consuming excessive spicy or hot foods can irritate the mucous membranes and skin above the lips. The irritating components in these foods may cause local blood vessel dilation, leading to redness and a burning sensation. Avoid spicy and excessively hot foods, and opt for mild, gentle diets instead.

3. Cheilitis: Inflammation of the lips (cheilitis) may result from bacterial infection or habitual lip-licking. This condition often presents with redness and a burning sensation above the lips, possibly accompanied by flaking and cracking. As directed by a physician, topical antibiotics such as erythromycin ointment, chlortetracycline ointment, or mupirocin ointment may be used to reduce inflammation.

4. Contact dermatitis: Exposure of the skin above the lips to certain allergens, such as cosmetics or metal jewelry, may trigger contact dermatitis. Symptoms include localized redness, burning, itching, and sometimes papules or blisters. According to medical advice, topical corticosteroids such as hydrocortisone butyrate cream, desonide cream, or fluocinolone acetonide cream may be applied to alleviate allergic reactions.

5. Perioral dermatitis: Long-term use of fluoridated toothpaste or topical corticosteroids may induce perioral dermatitis. This condition typically manifests as redness and a burning sensation above the lips, with surrounding papules or pustules and mild itching. Depending on the severity, medications such as tacrolimus ointment, pimecrolimus cream, or metronidazole gel may be prescribed to control the condition.

In daily life, maintain good lip hygiene and avoid harmful irritants; eat a balanced diet and maintain regular sleep patterns. Seek medical care promptly if any abnormalities occur on the lips.
