When will the redness at the corners of the mouth from eating pineapple improve?

Eating pineapple and subsequently developing redness at the corners of the mouth may be due to an allergic or irritant reaction caused by bromelain or acidic substances in the pineapple. Generally, the recovery time for redness at the corners of the mouth after eating pineapple depends on the severity of symptoms. Mild cases may resolve within 3–5 days, while more severe cases may take 1–2 weeks to heal, with variations depending on the individual. Detailed analysis is as follows:

If an individual has a relatively strong constitution and only experiences mild redness at the corners of the mouth without other discomforts such as pain or itching, the recovery period is usually short. In such cases, simply stopping pineapple consumption, cleaning the corners of the mouth, and applying cold compresses may alleviate the redness within 3–5 days.

If an individual has a weaker constitution or experiences more severe redness accompanied by discomforts such as pain, itching, or blisters, the recovery period may be longer. In these cases, in addition to the basic measures mentioned above, treatment with topical or oral medications under medical supervision may be necessary. Recovery could then take 1–2 weeks or even longer.

In daily life, if redness at the corners of the mouth occurs after eating pineapple, it is recommended to immediately stop consuming pineapple and gently wash the area around the mouth with lukewarm water to remove any residual pineapple components.
