Dr. Wang Xiaoyan
Dry and cracked lips are a common symptom that can be caused by various factors. The main causes include:
1. Environmental factors: Dry climate or cold weather can lead to insufficient moisture in the lips, causing them to become dry and cracked. Prolonged exposure to wind may also exacerbate this condition.
2. Vitamin deficiency: A deficiency in vitamin B2 can result in dry and cracked lips. These vitamins are essential for maintaining the health of the skin and mucous membranes.
3. Dehydration: Insufficient water intake or dehydration caused by certain illnesses can affect the lips' moisture levels, leading to dryness and cracking.
4. Allergic reactions: Allergic reactions to certain foods, cosmetics, or medications may cause dry and cracked lips, often accompanied by other symptoms such as redness, swelling, and itching.
If dry and cracked lips are severe or persistent, it is advisable to consult a doctor.
