5 Simple Steps to Boost Your Skin Microbiome Health and Diversity

Balancing your skin microbiome starts with spending time in nature. From soil microbes encountered while gardening to beneficial bacteria in fresh air, nature provides a simple, natural way to rebalance your skin’s microbial diversity. Research shows that exposure to green spaces enhances your skin's microbiome (Selway et al., 2020) (Ruokolainen et al., 2015), improving its natural defenses and resilience.

Activities like walking, hiking, or gardening can introduce these beneficial microbes to your skin (Saarenpää et al., 2024). Wild swimming, for instance, exposes your skin to waterborne bacteria, which can support microbiome balance and diversity.

A large study linked spending at least 120 minutes a week in nature with better self-reported health and wellbeing, and it made no difference whether that time came in one long visit or several shorter ones (White et al., 2019). If that seems unachievable, break it into smaller daily sessions, like 20-minute walks in a park or a quick dip in a natural water source. Spending time outdoors not only reduces stress but also helps rebalance the microbiome, which is essential for healthy, glowing skin.

Spending time in nature isn’t just relaxing: research suggests it can support and balance your skin microbiome naturally.

Regular interactions with animals can help rebalance your skin microbiome in a fun and natural way. Pets or other animals introduce a variety of beneficial microbes, enhancing your skin’s resilience and diversity (Trinh et al., 2018).

Studies show that pet owners, especially those with frequent and close contact, often share some of their microbiota with their pets, helping to balance microbiome health (Wetzels et al., 2021). Even if you don’t own a pet, visiting dog parks, volunteering at shelters, or spending time with friends’ animals can allow these beneficial exchanges to happen.

Animals act as carriers of environmental microbes that support microbiome diversity, enriching your skin’s ecosystem. Whether you’re cuddling a pet or volunteering at a shelter, interacting with animals is a simple way to help rebalance and support your skin microbiome.

The link between gut health and skin health, commonly referred to as the gut-skin axis, plays a major role in improving skin microbiome diversity (De Pessemier et al., 2021). A healthy gut microbiome produces compounds like short-chain fatty acids that travel through your body, helping to balance and support your skin microbiome naturally.

On the other hand, poor gut health caused by low-fiber diets, processed foods, or stress can lead to skin issues like dryness, sensitivity, and inflammation.

To support the gut-skin axis, focus on eating fiber-rich foods like vegetables, legumes, and whole grains. Incorporating fermented foods like yogurt, kimchi, or sauerkraut can also boost probiotics in your gut, which contribute to both gut health and glowing, healthy skin.

Looking to improve your gut microbiome for long-term skin benefits? Start with a daily high-fiber smoothie or fermented snack to nourish both your gut and your skin.

The skincare and household products you use every day play a huge role in your skin microbiome’s health. Ingredients like synthetic fragrances, harsh surfactants, and certain preservatives can strip your skin of beneficial microbes, weakening your skin barrier and increasing irritation (Draelos, 2018) (Carvalho et al., 2023).

Even products like laundry detergents and deodorants leave residues that may interact negatively with your microbiome (Mayerhofer and Pali-Schöll, 2024). Over time, repeated exposure to these residues can disrupt your skin’s delicate microbial ecosystem, reducing its ability to maintain a natural balance.

To support your microbiome, choose microbiome-safe products that are gentle and free of unnecessary preservatives or harsh ingredients. Look for options labeled as microbiome-friendly skincare or use apps to assess product safety and their impact on sensitive skin.

By switching to microbiome-friendly alternatives, you can protect your skin’s natural balance and avoid unnecessary disruption. Knowing your products is a key step to supporting your microbiome naturally.

Protecting your skin microbiome starts with understanding how certain ingredient categories in leave-on products can impact its balance. Research shows that harsh preservatives, alcohol-based formulations, and aggressive exfoliators in skincare products can disrupt the microbiome, potentially harming its natural equilibrium (Carvalho et al., 2023). This can weaken your skin’s defenses, leading to irritation, increased sensitivity, or a compromised skin barrier.

Laboratory studies suggest that some preservatives commonly used in leave-on cosmetics can inhibit or kill beneficial skin bacteria such as Staphylococcus epidermidis, even at the maximum concentrations permitted in skincare formulations (Zhang et al., 2023). Such disruptions can impact your skin's ability to maintain a healthy balance, making it more vulnerable to external stressors and irritation.

Choosing microbiome-friendly products with gentler formulations can help maintain the natural harmony of your skin. Opt for products designed to support rather than disrupt, and avoid overuse of formulations with antimicrobial preservatives or other stripping agents. Transitioning gradually to gentler options allows your skin to adjust and encourages a healthier, more resilient microbiome over time.

Your skin microbiome is influenced by more than just the products you use: it’s a reflection of your entire lifestyle (Wallen-Russell and Wallen-Russell, 2017) (Wallen-Russell and Wallen-Russell, 2020). From spending time in nature and interacting with animals to eating gut-friendly foods and being mindful of your household products, small changes can have a big impact on the health and diversity of your skin’s microbial ecosystem. By taking a balanced, intentional approach to your habits and choices, you can support your skin microbiome and, in turn, enjoy healthier, more resilient skin.

Looking after your skin microbiome isn’t complicated. It’s about making mindful, science-backed choices in your everyday life. Start today and take the first step toward glowing, healthy skin by prioritizing your skin microbiome health. Your skin will thank you.
