1, dark circles-black renal insufficiency. The formation of eye circles may be due to too much waste deposited in the blood. The skin of the lower eyelid is thinner than other parts, which is the easiest to reflect the color of blood. If the beautician sees a customer with serious dark circles under his glasses, he can ask her if she hasn't slept well recently, and if she feels stressed or overtired. Then tell her to nurse her kidneys more often, because the renal insufficiency that dominates the urinary and reproductive organs will also make her eyes dull. Tell customers to eat more black food.

2, eyelid edema-body fluid disorder. The eyelids are swollen badly. You may have a fluid disorder. Ask the customer if she is weak and thirsty recently, and tell her that the kidney may be "playing tricks". A healthy kidney can smoothly excrete excess water from the body. When water is insufficient, it will slow down metabolism and store water in the body, thus causing mild edema.

3, fat particles-high cholesterol. If you see more wrinkles and fat particles in customers' eyes, ask them if they didn't notice when applying skin care products, and teach them how to apply skin care products correctly. At the same time, we should also tell customers that there are many fat particles around the eyes, which also reflects the high cholesterol. If it is serious, we suggest that the other party go to the hospital for examination.

4, eye of a needle-low immunity. Japanese medical experts have found that long needle eyes indicate that your immunity is declining, and bacteria can easily enter your eyes from the root of eyelashes, causing inflammation. If there are repeated pinholes, you'd better go to the hospital for a comprehensive health check-up.

5, the whites of the eyes are yellow-there is a problem with the liver and gallbladder. If the eyes are blurred, there may be something wrong with the liver and gallbladder. Bile is a yellow-green liquid secreted by liver cells and stored in gallbladder. When there is something wrong with the gallbladder or liver, bile will flow into the blood, making the whites of the eyes yellow.
