Since it is an acid, a test in the hollow of the elbow is recommended before any use.

Polyglutamic acid was first discovered in jellyfish to help them retain moisture in salt water. It is also a main component of the sticky, stringy paste in Nattô, traditional Japanese food made from fermented soybeans. It is able to absorb up to 5,000 times its weight in water, developing an absorbent microgel on the skin that swells and traps water, preventing its evaporation.
