Lip color is abnormal.

The color of the lips is different. If the lips are black and purple for a long time, it is recommended to go to the hospital to check the heart. If the lips turn white in the short term, it is likely to be nutritional anemia in the near future. Eat spicy food, or your lips will change color when stimulated. After exercise, or eating spicy food, the blood on the lips will also become active. Because the lips are thin, it is easy to see discoloration, and so is the face, but the skin on the face is thick and difficult to see.
