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 cause various diseases, such as heart disease or respiratory diseases, and even cause bronchial stenosis. Long-term inhalation of dust will increase the prevalence of asthma and lung diseases and early death rate.

The skin is in direct contact with dust on the outermost side of our body, which acts as a barrier between the organism and the environment. If often exposed directly to pollution, this barrier function will be reduced. 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 a profound effect on skin health. In the short term, it may cause premature aging, lack of water, and increase wrinkles. In the long run, damaged skin cannot be repaired, and losing the ability to protect the body from environmental factors may cause serious diseases such as skin cancer.

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

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