4. Cracked and Extremely Dry Lips
Not every unusual-looking lip lesion is an infection.
Cold weather, dry air, dehydration, frequent lip licking, certain medications, irritants, and allergic reactions can all contribute to chapped or cracked lips.
Repeatedly licking the lips can actually make dryness worse. Saliva evaporates quickly and can disrupt the skin barrier, creating a cycle of dryness and irritation.
Using a bland, fragrance-free lip moisturizer or petrolatum-based protective ointment may help uncomplicated dryness. But persistent cracks that do not improve deserve attention.
5. A Sore That Keeps Coming Back
A recurring lesion is worth noticing.
If essentially the same area repeatedly develops discomfort, blisters, crusting, or another visible change, keep track of when it happens and what preceded it.
For example:
- Did it occur after significant stress?
- Did you recently have an illness?
- Was there substantial sun exposure?
- Did you start using a new cosmetic product?
- Did you experience trauma or irritation around the mouth?
- Does it appear in approximately the same location each time?
These details can be useful when speaking with a healthcare professional.
6. Changes That Do Not Heal
An isolated minor irritation may resolve relatively quickly. A lesion that remains, repeatedly breaks down, or progressively changes is different.
Persistent sores should not automatically be assumed to be something serious, but they should not simply be ignored either.
A healthcare professional can examine the area and determine whether testing or treatment is necessary.
This is particularly important if the lesion continues to enlarge, repeatedly bleeds, becomes increasingly painful, or develops a persistent unusual appearance.
