冬天空气干燥,孩子嘴唇容易干裂,而且一旦嘴唇干裂,孩子就喜欢用舌头去舔。但是越舔嘴唇会越干。这是因为,经常舔会舔掉皮肤表面的保护层,皮肤失去保护,更容易失水,这样,就形成越干越舔,越舔越干的恶性循环。 The air is dry in winter, the child’s lips are easily chapped, and once the lips are cracked, the child loves to tongue out. But the more you lick your lips, the harder it will be. This is because, often licking lick the protective layer of the skin surface, the skin loses its protection, more likely to dehydration, so that the more dry the more licking, the more licking the more vicious circle.
