Dark circles under the eyes are an increasingly prevalent problem among adults, typically caused by shadowing in the hollow of periorbital muscles and lax skin. Numerous cosmetic formulations have been created to address dark circles under eyes such as skin-firming products containing isoflavonoids (phytohormones), saponins, and peptides as well as plant extracts such as salvia miltiorrhiza and rhizoma gastrodiae as well as nicotinic acid and camellia oil.
