What is the impact of pathogenic bacteria on skin health?

Pathogenic bacteria have a significant negative impact on skin health, primarily by leading to skin infections and inflammatory conditions. When harmful bacteria penetrate the skin barrier, they can trigger the body's immune response, resulting in inflammation. This can manifest as various skin issues, such as acne, cellulitis, or other infections.

For example, the presence of bacteria like Propionibacterium acnes in pores can contribute to the development of acne by causing inflammation and clogged pores. Even common conditions such as impetigo and folliculitis arise from pathogenic bacterial infections, illustrating the detrimental effects these microorganisms can have on the skin.

In contrast, moisture enhancement, improved barrier function, or reduced acne risk is associated with beneficial bacteria or healthy skin practices. These are not outcomes of pathogenic bacteria, which emphasize the importance of understanding the role of different types of bacteria in skin health.
