Dry and peeling lips can be caused by a variety of factors, including dehydration, sun damage, vitamin deficiencies, eczema, contact dermatitis, skin picking and licking, poor quality lip balms, and yeast infections. Some lip balms contain ingredients that can irritate or dry out the skin, such as menthol, salicylic acid, cinnamic aldehyde, and balms with flavoring. To prevent and heal dry, chapped lips, here are some tips:

• Drink plenty of water to stay hydrated.
• Use lip balm that contains SPF 30 or higher and avoid products that contain irritating ingredients.
• Avoid licking, biting, and picking at your lips.
• Use a humidifier at home to add moisture to the air.
• Avoid holding items made of metal with your lips.
• Avoid salty and spicy foods that can cause skin irritation and water loss.
• Be mindful of medications that can cause dry, peeling lips and use lip balm frequently.

Its important to note that persistent lip dryness can also be a sign of a deficiency in vitamins B and C, iron, zinc, or folic acid, and multi-vitamin supplements may help. If dry, chapped lips persist for more than 2-3 weeks, its recommended to consult a dermatologist.
