Your skin’s surface hosts a controlled ecosystem of diverse microbiome not just impacted by environmental and external factors.
The most dominant types include:
* Staphylococcus epidermidis: A very common, mostly beneficial bacterium that helps prevent dangerous invaders from colonizing your skin
* Cutibacterium acnes: Found primarily in hair follicles and sebaceous glands, they feed on sebum (oil). An overgrowth of certain strains is linked to acne.
* Corynebacterium: Another common genus that thrives in oily or moist areas of the body, like the armpits.
The gut-skin axis is a dynamic, bidirectional relationship between the microorganisms in your digestive tract and the ecosystem on your skin. When gut health is compromised, systemic inflammation and altered immune responses frequently manifest as skin conditions like acne, eczema (atopic dermatitis), psoriasis, and rosacea.
