We often see people with red cheeks after drinking. What is the reason? It turns out that there are two kinds of enzymes in human body that act on alcohol. There is an enzyme called alcohol dehydrogenase, which can quickly convert ethanol into acetaldehyde. People who contain a lot of this enzyme in their bodies often have blushing symptoms in a short time after drinking.

The other is called acetaldehyde dehydrogenase. People who blush after drinking only have the former enzyme but not the latter enzyme, so acetaldehyde accumulates rapidly in the body and cannot be metabolized. Therefore, their faces will turn red for a long time, and they can only count on P450 (a group of oxidases with low specificity) in the liver to slowly metabolize the alcohol intake.

Simply put, acetaldehyde in alcohol can dilate capillaries. After drinking alcohol, acetaldehyde in alcohol makes the capillaries on people's faces dilate, and the more blood passes through, the people's faces will turn red.

Can red bloodshot skin drink?

Actually, it's okay to drink a little, but Mr. Sophia Kao doesn't recommend people with red blood skin to drink frequently, because drinking is usually in a state of revelry and excitement. If a person is excited, it will stimulate the adrenal gland to secrete too much and stimulate blood circulation, which will lead to vasodilation. If drinking alcohol stimulates blood vessels in this state, it will not increase the pressure on blood vessels!

If you are in this situation for a long time, you may have many pimples and pustules that look like acne. In the later stage, the sebaceous glands in the nose are swollen and the nose is deformed. This is rosacea, which is why men are more prone to rosacea, because they generally socialize more.

Therefore, it is best not to drink alcohol for the skin with red blood. Even if you want to drink, you should only drink a little, and don't drink too much.
