Microbiomes are complex ecosystems of microscopic organisms that live on skin, in the environment and on surfaces all around us. These communities of microorganisms play an important role in maintaining balance within the environments where people and animals live.
As scientific understanding of the microbiome continues to expand, interest in beneficial bacteria - often referred to as probiotics - has grown beyond digestive health. Researchers are increasingly exploring how microbial balance influences skin, indoor environments and the wider ecosystems we interact with every day.
In this article, we explore what microbiomes are, where they exist, and why maintaining microbial balance matters for pets, people and homes. If you're new to topical probiotics, you may also find our guide explaining how probiotics work on skin and surfaces helpful. We also look at how probiotic approaches – such as LUCAA+ probiotic pet care and Provilan Clean probiotic cleaning products – are designed to support healthier microbial ecosystems on skin and surfaces.
Quick Answer: What are surface probiotics?
Surface probiotics are beneficial microorganisms applied to skin or surfaces - often in spray form - to support microbial balance. Instead of trying to eliminate all microbes, probiotic approaches introduce helpful bacteria that compete with less desirable microorganisms for space and nutrients. Over time, this encourages a more stable microbial environment on skin, in pet environments and within indoor spaces.
What is a microbiome?
A microbiome is the community of microorganisms that live within a specific environment. These microorganisms include bacteria, fungi, viruses and other microbes that interact with each other and with their surroundings.

Where are microbiomes found?
The microbiome is most widely known for its role in the digestive system. However, microbial ecosystems exist almost everywhere.
Microbiomes can be found:
- on human and animal skin
- in the mouth, ears and eyes
- on indoor surfaces and fabrics
- in soil, water and air
- throughout homes and buildings
Every person, animal and home hosts a microbiome that is unique and constantly evolving, influenced by environmental conditions, lifestyle and daily routines.
Why microbial balance matters
Microorganisms are invisible to the naked eye, yet they represent one of the most abundant forms of life on Earth. Scientists estimate that the human body contains trillions of microbial cells alongside human cells.
Although microbiome science is still evolving, many researchers now recognise that balanced microbial communities are closely linked to the health of people, animals and ecosystems.
When microbial communities are balanced, different organisms coexist in a stable environment. Beneficial microbes can help limit the growth of opportunistic organisms that may otherwise cause problems.
Growing research interest in microbiomes is widely discussed by publications such as BBC Future and Environmental and Human Microbiome for Health, reflecting how rapidly scientific understanding of microbial ecosystems is evolving.
The gut microbiome
The gut microbiome is the most extensively studied microbial ecosystem. It plays an important role in digestion and nutrient absorption, and emerging research suggests it may influence many other bodily systems.
Scientists are increasingly exploring how gut microbes interact with the immune system, metabolism and even aspects of mental wellbeing.
Maintaining a healthy gut microbiome is often associated with lifestyle factors such as:
- balanced nutrition
- stress management
- regular exercise
However, factors such as antibiotics, environmental pollution and dietary changes can disrupt microbial balance – a process sometimes referred to as dysbiosis.
The skin microbiome in people and pets
Just like the gut, the skin hosts its own diverse ecosystem of bacteria, yeasts and other microorganisms.
A balanced skin microbiome supports the skin’s natural barrier, contributing to overall skin comfort and resilience in both people and animals.
When microbial balance on the skin is disrupted, opportunistic microbes may grow more easily. In pets, this imbalance can contribute to irritation, odour, yeast overgrowth or recurring skin discomfort.
Environmental factors that may influence the skin microbiome include:
- harsh soaps or cleaners
- environmental pollution
- antibiotics
- stress or dietary changes
- frequent exposure to strong disinfectants
Maintaining microbial balance on the skin is therefore an important part of everyday skin care.
The microbiome inside your home
Microbial ecosystems also exist throughout indoor environments. Researchers studying the indoor microbiome have found that buildings develop their own microbial signatures influenced by occupants, pets, ventilation and cleaning habits.
Studies also suggest that diverse microbial environments help to support healthier indoor ecosystems compared with environments that are repeatedly sterilised using strong antimicrobial cleaning products.
This growing understanding has led to increased interest in how everyday cleaning routines influence microbial balance inside homes.
How do probiotics work on skin and surfaces?
When probiotic products are applied to skin or surfaces, they introduce beneficial microorganisms that interact with the existing microbial community.
These beneficial microbes help support microbial balance by:
- competing with unwanted microbes for space
- breaking down organic residues that unwanted microbes feed on
- contributing to a more stable microbial ecosystem
In simple terms, probiotic cleaning introduces beneficial microbes that support microbial balance on surfaces rather than attempting to eliminate all microorganisms.

Supporting the pet skin microbiome
Animals have diverse microbial communities across their skin, ears, eyes and mouth. Each of these environments contains its own microbiome.
LUCAA+ probiotic pet care products are designed as topical sprays and washes that help support microbial balance on these surfaces. The range includes products for:
- skin and coat care
- ear hygiene
- eye care
- dental care
- pet bedding and environments
These products introduce beneficial microorganisms sourced from plant environments. When applied regularly, these microbes encourage a balanced microbial ecosystem on the skin and surrounding surfaces.

Supporting the home microbiome with probiotic cleaning products
Cleaning routines also influence the microbial environment of indoor spaces.
Traditional antibacterial cleaning products are designed to remove or kill microorganisms. While this can reduce microbes temporarily, it may also reduce microbial diversity within indoor environments.
Provilan Clean probiotic cleaning products take a different approach. Instead of focusing solely on eliminating microbes, they introduce beneficial bacteria that continue working after cleaning.
These probiotic microbes break down organic residues such as dirt, odours and allergens while competing with less desirable microorganisms for space and nutrients.

Probiotic cleaning vs traditional disinfectants
Many conventional disinfectants aim to reduce microorganisms on surfaces quickly. While this can be useful in situations where immediate sanitation is required, microbial communities naturally re-establish themselves over time.
Probiotic cleaning takes a different approach. Instead of focusing on removing microorganisms entirely, it introduces beneficial microbes that help support microbial balance on surfaces.
These microbes:
- break down organic residues that unwanted microbes feed on
- compete with other microorganisms for nutrients and space
- help maintain a more stable microbial ecosystem over time
Why scientific interest in the microbiome is growing
Over the past two decades, scientific understanding of microbial ecosystems has expanded rapidly. Researchers are increasingly recognising that microbiomes influence many aspects of health and environmental balance.
As a result, scientists and environmental researchers are exploring how everyday environments - including homes, pets and indoor surfaces - develop their own microbial ecosystems.
This growing awareness is beginning to influence how people think about hygiene, cleaning and everyday pet care.
