Gold foil is not absorbed by skin, and active gold foil can improve skin permeability, adjust skin acid-base balance, nourish skin and prevent ultraviolet damage.

The production of gold foil is that the gold bars with a gold content of 99.99% are processed through more than ten processes, that is, they are constantly beaten and then turned into gold foil. Real gold foil is as light as a feather, as soft as satin, as thin as cicada's wings, and its thickness is less than 0. 12 micron, which is thinner than a long piece of paper burned to ashes. Gold foil is edible (gold foil dinner, gold foil wine, gold foil candy), can be used for cosmetics (beauty, anti-aging), can be used as gold foil thread, and can also be used for high-grade ink painting formula. At present, hospitals have studied the use of gold foil in surgical suture surgery.
