Microbiome

The community of bacteria, fungi, and other microorganisms that live on your skin and help maintain its balance.

Your skin microbiome is the diverse ecosystem of trillions of microorganisms — bacteria, fungi, viruses, and mites — that naturally reside on your skin's surface. Far from being something to scrub away, this living community plays an active role in how your skin functions day to day. A balanced microbiome supports the skin barrier, helps regulate pH, and contributes to your skin's ability to manage moisture levels and respond to environmental stressors.

In skincare formulations, the microbiome is supported rather than directly "added to." Prebiotics (nutrients that feed beneficial organisms), probiotics (live microorganisms), and postbiotics (beneficial byproducts of microbial activity) are the three main ingredient classes you'll see. Products formulated with these aim to encourage a favourable microbial environment on the skin's surface. You'll often find them in gentle cleansers, serums, and moisturisers designed to work with your skin rather than strip it back.

This matters because an out-of-balance microbiome can coincide with increased sensitivity, dryness, or congestion. If your skin feels reactive after switching products or over-cleansing, microbiome-supportive formulations can be a gentle way to recalibrate. They pair well with simple, low-irritant routines and fragrance-free products. Avoid combining them with harsh exfoliants or strong actives that may undermine the environment you're trying to support.

Honest caveat: microbiome science in skincare is still relatively young. While the evidence base is growing, researchers are yet to define exactly what a "perfect" microbiome looks like, and it varies significantly from person to person. No single product can guarantee a balanced microbiome, and claims that sound too precise should be met with healthy scepticism. If you're experiencing persistent skin concerns that feel beyond the scope of routine adjustments, consider speaking with a dermal therapist or dermatologist for personalised guidance.
