Why postbiotics are driving the invisible skincare revolution

Biggest organ, biggest responsibility… your skin deserves better.

Protecting your skin barrier is critically important. It acts as your first line of defence against everyday environmental factors. It locks in moisture to keep skin healthy, hydrated, and strong, while also supporting the balance of your skin microbiome and, in turn, your gut microbiome. But when that barrier is weakened, it can trigger dryness, irritation, sensitivity, and flakiness, which is often linked to conditions like eczema and psoriasis.

That’s where postbiotics step in! These powerful byproducts of fermentation can:

Support and restore the skin barrier
Increase hydration and elasticity
Reduce redness and inflammation
Help manage specific skin conditions
Potentially delay signs of aging

Here at Chuckling Goat, our award-winning kefir naturally brews up its own postbiotic magic, such as organic acids, peptides, and vitamins. This plays a key part in why our kefir is so powerful for your gut, and why our award-winning soaps and lotions pack such a punch! We put our live-fermented kefir into every single bar and bottle. Now pair them together, and you’ve got the ultimate gut-skin dream team!

So, what are postbiotics?

This term refers to the waste left behind after your body digests both prebiotics and probiotics. Healthy postbiotics include nutrients such as vitamins B and K, amino acids, and substances called antimicrobial peptides that help to slow down the growth of harmful bacteria. Other postbiotic substances, such as short-chain fatty acids, help healthy bacteria flourish.

You can increase the amount of useful postbiotics in your system by increasing your intake of fermented foods – such as kefir, tempeh, and kimchi – and prebiotic, fibre-rich foods. Focusing on getting enough of the foods that promote a mix of healthy gut bacteria may help improve your overall health.¹

Recent focus on the use of probiotics and postbiotics, highlights not only their ability to modulate the skin microbiome and enhance barrier function, but they also exhibit anti-inflammatory properties. By including these in your skincare, it has the potential to improve your skin hydration, elasticity, and overall appearance, as well as in reducing signs of aging, such as wrinkles and fine lines.²

The gut-skin connection

What is happening inside your gut, will reflect through your skin!

Your skin isn’t just a barrier, it’s a living ecosystem. It moderates your temperature, backs up your immune system, and houses a bustling community of microbes. What you eat, how you wash, your age, and even your clothes all shape this busy ecosystem! But hit it with harsh products and you will strip away the good guys, leaving skin exposed. So treat your microbiome kindly with gentle products, smart habits, and nourishing foods, and your skin will pay you back with strength and glow.

The gut microbiome refers to the trillions of bacteria, fungi, and microorganisms that live in the digestive tract. These microbes perform a range of essential functions: breaking down food, synthesising nutrients, modulating the immune system, and producing signalling molecules that travel throughout the body, including to the skin.

Signs of a gut-skin imbalance

Inflammatory skin conditions such as acne, eczema, rosacea, or psoriasis that coincide with digestive issues (bloating, gas, or irregular bowel movements).
Food-related flare-ups where specific meals – especially those rich in sugar, dairy, or processed ingredients – seem to precede breakouts or redness.
Post-antibiotic sensitivity when skin worsens after a round of antibiotics, likely due to disrupted microbial diversity in the gut.
Dull or reactive skin, particularly when paired with signs of poor nutrient absorption like brittle nails or fatigue.

These clues, while not diagnostic on their own, can be early indicators of a compromised gut-skin axis.³

What makes our skincare so good?

We have the holy grail in our skincare range. We use all-natural ingredients free from all nasties! Because we put our own fermented kefir into our soaps and lotions, you end up with both probiotics and postbiotics being applied to your skin.

Research suggests that certain probiotic strains and their metabolites (postbiotics) may provide benefits such as improving the skin barrier function, reducing inflammation, and improving the appearance of acne-prone or eczema-prone skin.⁴.

Clinical studies have shown that probiotic and postbiotic ingredients in skincare can help maintain skin hydration, strengthen the barrier, improve radiance, and even reduce the appearance of fine lines and wrinkles – all while supporting a healthy balance of skin microbes.⁵.

Everyday skincare should nourish, not just cleanse. That’s why Chuckling Goat harnesses the power of postbiotics – naturally fermented, skin-loving compounds that support your skin microbiome and keep your skin healthy, balanced, and radiant every day.
