Skin Barrier Functions

The functions of the skin to prevent external stimuli and foreign substances, such as allergy-causing substances, bacteria, and viruses, from entering the skin and to prevent evaporation of water from the body are referred to as the skin barrier function. The skin of atopic dermatitis is naturally prone to dryness, and because the skin barrier function is impaired, it is […]

Reactive oxygen species

Oxygen and related molecules that are more activated than oxygen in the atmosphere, a general term for highly reactive compounds containing oxygen. They are unstable and react easily with various substances. In minute quantities, they are useful to the human body, but in large quantities they produce lipid peroxide, which causes arteriosclerosis, cancer, aging, and impaired immune function.
