First, if your lips are swollen, you may want to suspect cheilitis. Cheilitis is a dermatitis that occurs on the lips and includes exfoliative, contact, and actinic types.

In the case of contact cheilitis, it can occur due to habits such as frequently licking the lips with the tongue, or because of low humidity, wind, and irritants.

For example, lips may swell due to irritation or allergic reactions caused by products applied to the lips, such as lipstick or lip balm, as well as toothpaste, dental materials, or food.

Actinic cheilitis is cheilitis caused by excessive sun exposure, and it may mainly appear with dryness, peeling, and symptoms such as swelling.

As such, there are various types of cheilitis, and depending on the type, different symptoms may accompany it. Symptoms such as swollen lips, itching, and a burning sensation may occur.

Lip swelling can also occur due to herpes simplex. Herpes simplex is when small blisters develop on the lips as fatigue builds up.

If herpes simplex occurs inside the mouth, it is not a problem, but if it appears on the lips, it can be bothersome because it does not look aesthetically pleasing.

You may also experience lip swelling due to cheilitis. Inflammation can occur because of irritants such as the toothpaste or lipstick you use, and symptoms such as a burning sensation may appear together.

You can also experience this symptom due to angioedema, which is called anaphylaxis. It may cause the lips to swell and be accompanied by various symptoms such as headache and dizziness.

Also, when dead skin forms on the lips, many people tend to pick it off, but doing so can instead cause wounds, so it is best not to pick at it.

In addition, it is good to pay attention to moisturizing the lips in everyday life, and checking whether the cosmetics used on the lips contain irritants can help prevent symptoms.
