Skin Flora

Written by Reviewed by the SYNC editorial team Published Last reviewed Editorial standards

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.

Frequently asked

What is the difference between skin flora and the skin microbiome?

The terms are used interchangeably to describe the community of microorganisms living on the skin's surface.

Can skincare products affect skin flora?

Yes, harsh cleansers and over-exfoliation can disrupt the microbial balance, while gentle care and a healthy barrier help keep it stable.
