Skin Flora

Skin Flora — the community of bacteria, fungi, and other microorganisms that naturally live on the skin's surface, also called the skin microbiome. This ecosystem helps defend against harmful pathogens, supports the skin barrier, and interacts with the immune system to keep skin balanced.

Key points

• The skin hosts diverse microbes that vary by body site depending on moisture, oil, and temperature.
• A balanced microbiome helps crowd out pathogens and contributes to a healthy skin barrier.
• Harsh cleansing, over-exfoliation, and some ingredients can disrupt this microbial balance.
• Maintaining a gentle routine and intact barrier supports a stable, resilient skin flora.
