Itchy lips and blisters after applying lipstick
Itching and blistering of the lips after applying lipstick may be caused by conditions such as contact cheilitis, ectopic sebaceous glands, or herpes labialis. Treatment should be based on the specific cause. Details are as follows:
1. Contact Cheilitis
This usually refers to a localized irritant or allergic reaction of the lips triggered by exposure to external chemical substances. Due to inflammatory stimulation, symptoms such as blisters and itching may occur. Medications such as levofloxacin hydrochloride capsules or amoxicillin capsules may be used under medical guidance.
2. Ectopic Sebaceous Glands
This condition may be related to hormonal levels or trauma, and can cause skin irritation, resulting in symptoms such as papules and pain. Topical treatments such as tretinoin cream or fusidic acid cream may be applied as directed by a physician.
3. Herpes Labialis (Cold Sores)
This typically refers to a skin condition occurring at the junction of the oral mucosa and skin, which may lead to tissue lesions in the mouth, causing small bumps, redness, and swelling. Medications such as Liu Shen Wan (Six God Pills) or metronidazole buccal tablets may be used under a doctor's supervision.
In addition to the above causes, similar symptoms may also result from shingles, eczema, hand-foot-and-mouth disease, etc. Avoid scratching with hands and maintain local cleanliness.
