Your lips are made of skin that is soft and delicate. As a result, they can easily crack and split under certain conditions.

Since a split lip can develop gradually, it may be difficult to pinpoint the exact cause. Understanding possible reasons can help you determine the best way to treat and prevent future splitting.

Causes:

1. Weather

Exposing unprotected lips to the sun or coldness can lead to inflammation.

2. Dehydration

Dry lips sometimes due to dehydration.

3. Lip Licking

Licking your lips will cause your saliva evaporates from your lips, hence lips’ natural moisture evaporates too.

4. Lip Injury

Falling and hitting your mouth, biting your lip will cause split lips.

5. Allergy

An allergic reaction to certain ingredients in lipstick, toothpaste, moisturizers, or even some foods may cause a split lip.

6. Vitamin and mineral deficiency

Lack of Vitamins B2 (riboflavin), B1, B6, zinc and iron can also lead to split lips, especially at the corners of the mouth.

Treatment:

1. Apply lip balm with SPF or petroleum jelly to your lips.
2. Increase your fluid intake to keep your body and lips hydrated
3. Don’t lick your lips
4. Apply a cold compress to bleeding lips
5. Change the products if it causes crack lips
6. Get enough of Vitamins B, zinc and iron.

嘴唇干裂

嘴唇是由柔软细腻的皮肤制成。所以，它们在某些条件下很容易破裂和分裂。

由于唇裂会逐渐变化，因此可能很难确定原因。了解可能的原因可以帮助您确定治疗和防止将来干裂的最佳方法。

原因：

1. 天气

嘴唇暴露在阳光下或寒冷的气候下会导致炎症。

2.脱水

脱水容易导致嘴唇干燥。

3. 舔嘴唇

舔嘴唇会导致唾液从嘴唇蒸发，因此嘴唇的自然水分也会蒸发。

4.嘴唇受伤

跌倒并碰撞到嘴巴，咬住嘴唇会导致嘴唇裂开，且容易受伤。

5.过敏

对口红，牙膏，保湿剂甚至某些食物中的某些成分的过敏反应可能会导致嘴唇裂开。

6.缺乏维生素和矿物质

缺乏维生素B2（核黄素），B1，B6，锌和铁也会导致嘴唇裂开，尤其是在嘴角。

治疗：

1. 在您的嘴唇上涂上带有SPF或凡士林的润唇膏。
2. 增加水分摄入量，以保持身体和嘴唇有足够的水分
3. 不要舔嘴唇
4. 对于流血的嘴唇进行冷敷
5. 如果使用特定产品导致嘴唇裂开，请更换产品
6. 摄取足够的维生素B，锌和铁。
