How to Improve Your Microbiome (And Why It Matters for Your Skin)

Danielle Joubert - Jul 8, 2025

What Is the Microbiome, and Why Does It Matter?

Your skin's microbiome is an invisible ecosystem made up of a diverse range of microorganisms. Much like the balance of nature, the skin microbiome needs harmony to maintain a healthy, glowing complexion. Disruptions to this delicate balance, often caused by pollution, stress, or harsh skincare products, can lead to inflammatory skin conditions such as acne, eczema, and psoriasis.

In essence, a thriving microbiome is the foundation of a resilient skin barrier, which is vital for maintaining smooth, youthful, and radiant skin. But how can we nurture this essential ecosystem?

Understanding the Microbiome: Prebiotics, Probiotics, and Postbiotics

To better understand how to protect and enhance your skin’s microbiome, let's break down these key terms:

Prebiotics: These are substances that support the growth and function of beneficial microbes on your skin. Prebiotics essentially “feed” the good bacteria, helping them thrive and maintain balance in the microbiome.
Probiotics: These live microorganisms are naturally present on the skin. They play an essential role in stabilising the microbiome by keeping harmful bacteria at bay and promoting skin health.
Postbiotics: These are the beneficial byproducts produced by probiotics as they break down. Postbiotics include peptides, proteins, amino acids, hyaluronic acid, and ceramides - vital components that nurture your skin, promote hydration, and strengthen the skin’s barrier.

The balance between prebiotics, probiotics, and postbiotics is crucial for maintaining a healthy, vibrant skin microbiome. When this balance is disrupted, the skin becomes more prone to irritation, sensitivity, and imbalances.

How to Improve Your Skin’s Microbiome

External factors like environmental stressors, UV exposure, and irritating products can destabilise the skin’s microbiome. A comprehensive approach incorporating prebiotics, probiotics, and postbiotics is essential to restore balance and achieve healthier skin.

Here’s how to nurture your microbiome:

Choose Skin-Friendly Ingredients: Look for products enriched with peptides and probiotics. These ingredients help replenish the good bacteria on your skin, maintain hydration, and foster a healthy skin barrier.
Gentle Cleansing: Avoid harsh, stripping cleansers that disrupt the microbiome. Instead, opt for a gentle cleanser that preserves the skin's natural balance, preparing it to absorb the benefits of your skincare products.
Hydration is Key: A well-hydrated skin barrier is better equipped to defend against harmful environmental factors. Look for products that promote moisture retention while balancing your skin’s microbiome.
Protect Your Skin: Incorporate antioxidants, vitamins, and other skin-strengthening ingredients into your routine to protect your skin from pollutants, UV rays, and free radicals.

The Benefits of a Balanced Microbiome

When your skin’s microbiome is in balance, you’ll notice several positive changes:

Improved Hydration: A balanced microbiome enhances your skin's ability to retain moisture, leaving it soft, smooth, and supple.
Calmer, More Even Skin: As inflammation decreases, redness and irritation subside, leading to a more stable and even complexion.
Stronger Skin Barrier: With a healthy microbiome, your skin is better equipped to fend off environmental stressors, reducing the risk of premature aging and damage.
Radiant, Glowing Skin: A flourishing microbiome supports the production of essential skin nutrients like hyaluronic acid, peptides, and antioxidants, giving your skin that coveted healthy glow.

Ingredients That Support a Healthy Skin Microbiome

These powerhouse ingredients are known to help nurture the skin’s microbiome, strengthen the skin barrier, and promote calm, radiant skin:
