Description

Anti-dust composition

This article is about an anti-dust composition.

If dust accumulates in the body, the body's immunity will decline, which may lead to various diseases, such as heart disease or respiratory system diseases, and even cause bronchial stenosis. Long-term inhalation of dust will increase the prevalence of asthma and lung diseases, as well as early death Rate.

The skin, the outermost part of our body in direct contact with dust, acts as a barrier between the organism and the environment. This barrier function decreases with frequent direct exposure to pollution. In particular, since fine dust is 20 times smaller than pores, it easily penetrates the skin. In fact, air pollutants such as fine dust are known to have profound effects on skin health. In the short term, premature aging, lack of hydration, and increased wrinkles may result. In the long-term, skin is damaged beyond repair and loses its ability to protect the body from environmental factors, which can lead to serious diseases such as skin cancer.

Therefore, there is a need to develop cosmetics for isolating dust harmful to the skin (in severe cases fatal) from the skin.

In recent years, due to frequent going out, fine dust adheres to the hair and enters the As the number of cases on the skin or the human body increases, efforts are being made to reduce the adhesion of fine dust to the hair.
