Our guide to probiotics

Why do we care about bacteria?

In recent decades, research on the microbiome has grown to reveal that we host trillions of microorganisms in different parts of our bodies, including our skin. These microorganisms, such as bacteria, viruses and fungi, outnumber human genes. Rather than fighting them off, research has shown that eating fermented vegetables and prebiotic fibre is beneficial in engaging with the microorganisms. Probiotics are live microorganisms found in fermented foods such as sour milk and yoghurt and can also be ingested in concentrated form through supplements, which usually contain lactobacillus.

Can probiotics be useful for our skin?

Probiotics have shown promising potential for improving our skin's health and appearance. Several clinical studies have shown that certain probiotics can alleviate eczema, acne, and rosacea by limiting the growth of harmful bacteria. Human clinical studies have also supported these findings, with some showing that probiotics can alleviate eczema symptoms within three months of treatment. The mechanism behind these results is thought to be through competition with bad bacteria such as s.aureus and p.acnes. While more studies are needed to fully understand the effects of probiotics on the skin, current research suggests that probiotics may offer a natural, holistic approach to improving skin health and appearance.

Probiotics as anti-aging?

The belief that probiotics offer some magical formula for eternal health and beauty must be taken with a pinch of salt. However, there are studies that have shown a reduction in oxidative stress and inflammation in the skin, plus an improved barrier function and more moisturised skin as a result of taking probiotics. In another study, which looked at Japanese female students, participants drank probiotic-containing film milk with Bifidobacterium breve bacteria for four weeks. The results showed more moisture in the skin, improved absorption of nutrients, an increase in the volume of stool excreted and a reduction in facial wrinkles. At the same time, the secretion of sebum in the skin increased. Researchers from South Korea have also shown in a study that Lactobacillus plantarum can improve skin hydration, give skin more glow, reduce wrinkles and firmer skin. Although we're only talking about a small number of studies here, these are interesting observations. Further, consumption of the probiotic lactic acid bacteria L. paracasei has been shown to reduce skin sensitivity.

Lactobacillus reuteri - the anti-inflammatory guardian

Lactobacillus reuteri is a probiotic bacterium derived from breast milk and has unique anti-inflammatory properties. The first study with L reuteri related to skin health was done 20 years ago and since then several studies have been published with positive results. Together with the world-leading probiotics company Biogaia, we have studied the effects of L reuteri on skin health and published the results in the prestigious Journal of Experimental Dermatology 2019. The results showed that by applying a product with L Reuteri for 3 weeks to the skin, participants experienced a more varied and balanced skin microbiome, while skin texture improved, skin became softer and pore size decreased. But what also surprised us was that the participants' skin had significantly fewer fine lines and wrinkles. 

After five years of research, we have now launched our first product with L reuteri as part of our product portfolio, a probiotic concentrate. L.reuteri is the most well-studied probiotic bacterium globally with over 224 clinical studies and over 200 worldwide patents. Each bottle contains over 100 billion bacteria, which is more than 25 times more bacteria compared to other probiotic skin care products on the market. We are proud to be the first to market with a skin care product formulated with L.reuteri and look forward to continuing to improve skin health through our research.
