The skin is the organ most exposed to the outside world and serves as the first line of defense against chemical and microbial threats. It has a highly variable individual microbiological environment. Maintaining and improving skin health and integrity is an important goal in both acute and long-term care. It is widely recognized that skin health is important. Skin personal care products are widely used, but their impact on the molecular and microbiological diversity of the skin is unknown and uncertain. It is an important aspect of cosmetic dermatology, and scientists are working to develop new methods and materials to achieve this goal.
