What if the lips are sour, dry and swollen? Thank you for your questions.

Drink more water. If my skin is broken, I will apply thick lip balm before going to bed at night. My lips are so good. Just try it. There are many reasons for dry lips. The most common thing is to start from the corners of the mouth. This is a phenomenon of vitamin deficiency. You should eat more kinds of food, not partial food, especially fruits and vegetables. Another kind of dry lips is lack of water or dry mouth due to talking too much. At this time, there will be some waste skin accumulation where the corners of the mouth and lips meet. Once this happens, drink water in time and wash your lips. When the lips are dry and not serious, the lips will become warped. Don't tear it with your hands or pliers at this time, which will easily tear your lips and lead to pain and bleeding. You can carefully cut off the upturned skin on your lips with small scissors in front of the mirror. Some lips are chapped, red and bleeding, which may be due to lack of nutrition, but it is related to dry weather. When the wind is strong or cold, the moisture on the skin surface is not enough, and the moisture is absorbed by the dry air. It is best to apply colorless lip balm and lip oil frequently. Some people wipe their lips with glycerin, thinking that this will moisturize their lips. Actually, it is wrong, because rubbing glycerin will make their lips drier, so it is not suitable for use. In addition, more attention should be paid to getting rid of the habit of licking your lips or wetting your lips with saliva, because doing so will evaporate the water on your lips. Many ladies, especially girls, like to make this mistake, so their lips are often dry. According to the advice of beauty experts, most of the dry lips of women are related to dry skin, so it is necessary to replenish water and oil, and it is best to massage the lips frequently. It's not difficult to massage your lips, and it doesn't take much time. As long as you apply a layer on your lips before going to bed every morning and evening, and then gently massage with the fleshy part of your fingers, it will help promote blood circulation, make your lips get oxygen, increase nutrition, and make the moisturizer reach the subcutaneous area of your lips quickly. After a few massages, wipe it off with paper and apply a layer of colorless lip balm, and your lips will become moist. Buy bezoar disinfectant, and then put toothpaste on your bubbles, which will make you feel cold. If the cold feeling is gone, you can wash the dried toothpaste with a clean cloth and then reapply it. Eat something simple, just clear your mouth.
