The reason why the mung bean mask feels tingling is allergic to mung beans or the skin is extremely dehydrated. When the skin is extremely short of water, small wounds will appear on the surface of the skin because it is too dry, and tingling will occur when the mask is suddenly replenished, mainly because the cells have dried up due to lack of water and suddenly become uncomfortable when they are filled with water. Moreover, the mung bean mask can be deeply cleaned and has certain irritation, and it will sting when it meets small wounds.

Some people are naturally allergic to mung beans, so they can't eat or even touch them. The main component of mung bean mask is mung beans, which is not very friendly to people who are allergic to mung beans. Some people with sensitive muscles can't stand the irritation of mung bean mask, so they will feel tingling.
