Background

With the development of society, the living standard is improved, and people pay more and more attention to the skin health condition of the people, because the skin health condition can influence the appearance of the people and the mood of the people. Skin water loss is a common skin problem, because of skin water loss, poor skin water circulation, slow skin metabolism, atrophy of blood vessels supplying skin nutrition, weak skin cell vitality, hypodermal fat reduction, loss of collagen, elastin and the like, and finally skin wrinkles can be formed. Whereas lack of water is indicative and vicious circle of water is the source. The skin has poor water circulation, and the skin has dry, peeled and false wrinkles. If the skin is not timely supplied with water, the skin water circulation is smooth, the malignant circulation of the skin water is easy to occur, the skin is changed from dry, peeled and loose to sagged, the false wrinkles are converted into true wrinkles, and the skin is in serious old and sick state.

The facial mask is used as a common skin care product in daily life, and the skin care product can promote the pore expansion of the skin, promote sweat gland secretion and metabolism by using the short time covered on the face, so that the oxygen content of the skin is increased, the skin can promote the removal of the products of epidermal cell metabolism and accumulated grease substances, and the high-concentration nutrition components in the facial mask liquid can be quickly fed into the skin, so that the skin can be quickly and effectively cared.
