The reason for the redness of the wine all over the body starts with the drinking. Drinking whether you drink wine, red wine, white wine, beer, drink in is ethanol. After ethanol enters the body, it is first metabolized in the liver and converted into acetaldehyde under the action of ethanol dehydrogenase. Acetaldehyde is the main cause of skin redness all over the body, because acetaldehyde has the effect of dilating capillaries, so if the subcutaneous capillaries are dilated, it will cause skin redness all over the body. If the subcutaneous capillaries of the face are dilated, it will cause redness of the facial skin. If the enzyme is powerful, it will dehydrogenate acetaldehyde to form acetic acid, which will form carbon dioxide, water and fat under the action of acetic acid kinase. The human skin capillaries will not appear dilated, so there will be no redness of the skin all over the body.
