Chapped Lips: What to do when they don't heal?

Chapped lips usually heal after two to three weeks of regular application of a moisturizing, nourishing lip balm.

If this is not the case, a medical consultation may be necessary. Indeed, it is not normal to constantly have chapped lips and only a health professional can determine the underlying cause and propose an appropriate treatment.

• If chapped lips are due to an allergic reaction.

  As mentioned earlier, chapped lips that do not heal may indicate a contact allergy to a lip product or a toothpaste, for example. The most common allergens include fragrances, essential oils, and certain preservatives. To establish this diagnosis, the doctor may perform patch tests which involve applying small amounts of potentially allergenic substances to the skin and observing the reaction. If the allergy is confirmed, the treatment relies on avoiding the allergen. Meanwhile, taking antihistamines or corticosteroids can speed up the disappearance of symptoms and the healing of chapped lips.

• If chapped lips are due to a bacterial or fungal infection.

  Infected chapped lips are typically identified by oozing cracks, crusts, and pain. Infections often occur when untreated chaps become an entry point for pathogens. The treatment depends on the nature of the infection. If it is bacterial in origin, the doctor will prescribe a topical or oral antibiotic. On the other hand, for a fungal infection, an antifungal in the form of a cream or tablets will be recommended.

• If chapped lips are a result of a nutritional deficiency.

  Several studies have shown that a nutritional deficiency in iron, zinc, or B vitamins, particularly B2 or B6, can weaken skin tissues, including those of the lips, and make their repair more challenging. In addition to persistent chapping, a feeling of fatigue or brittle nails can indicate a nutritional deficiency. If suspected, a doctor can conduct blood tests to measure the serum levels of iron, zinc, and vitamins.

  If a deficiency is identified, the solution relies on a dietary adjustment to include foods rich in the missing nutrients: red meat, fish, eggs, green vegetables for iron; seafood, seeds, and nuts for zinc; and whole grains or brewer's yeast for B vitamins. Sometimes, dietary supplements may be prescribed. Once the intake is corrected, the lips usually return to their normal state within a few weeks.

In the event of chapped lips that do not heal, it is recommended to consult a healthcare professional. This individual can not only propose a suitable solution, but also ensure that this condition is not a sign of a more serious underlying ailment.
