Asian Glow, a name for Alcohol Flush Reaction, is a common genetic, inherited, mutation in an enzyme that is vital for the metabolism of alcohol. The enzyme called aldehyde dehydrogenase 2 (ALDH2) is deficient, and the significant decrease in its activity leads to a buildup of acetaldehyde which is a toxic product of the breakdown of alcohol. This mutation is present in anywhere from at least 30% to even 70% of people of East Asian descent. It occurs in around 8% of the world’s population, or 560 million people. 

 

People with this syndrome tend to turn red or pink quickly after consuming alcohol. There is a common misconception that turning red is the only consequence of this condition, but in reality, there are various grave health risks associated with it.
