The concentration of alcohol (ethanol) should not be too high, otherwise it may irritate the skin and absorb a lot of water from the epidermis.
Long-term exposure to ethanol can lead to dryness, desquamation, chapped skin and dermatitis.
Facial flushing after drinking is caused by the temporary dilation of blood vessels under the skin, because there is an efficient alcohol dehydrogenase in this kind of human body, which can quickly convert the alcohol in the blood into acetaldehyde, and acetaldehyde has the function of dilating capillaries, which will cause redness and even flushing of the skin.
