Introduction
Cold sores on the lips are usually caused by viral infections, allergies, or inflammation, and pearl powder should not be used. Pearl powder has no antiviral or anti-inflammatory properties, and its particles may irritate damaged mucous membranes, worsening discomfort and potentially delaying healing. If the blisters are clustered, painful, or do not improve within a week, medical attention is recommended. The main component of pearl powder is calcium carbonate.

Water blisters on the lips are usually caused by viral infections, allergies, or inflammation and should not be treated with pearl powder. Pearl powder lacks antiviral and anti-inflammatory properties, and its particles may irritate damaged mucous membranes, worsening discomfort and potentially delaying healing. If blisters are clustered, painful, or do not improve within a week, prompt medical attention is recommended.

Pearl powder is primarily composed of calcium carbonate. Although it has mild astringent effects, the skin on the lips is delicate. Applying pearl powder to broken blisters may leave particles trapped in the wound, increasing the risk of bacterial infection and possibly causing local itching or swelling.

Water blisters on the lips require a clean and dry environment to allow the damaged mucosa to heal naturally. Pearl powder does not address the underlying causes of blisters, and using it indiscriminately may delay proper treatment—especially since virus-induced blisters often require prescription medication as directed by a healthcare provider.

To promote healing, keep the lips clean and avoid licking or squeezing the blisters. Use a gentle, non-irritating lip balm for moisturizing, maintain a bland diet avoiding spicy or hot foods, drink plenty of water to stay hydrated, and minimize friction to support wound recovery.
