Probiotic skincare helps preserve the diversity of the skin microbiome, which is essential for maintaining the skin's balance and immune system

What is probiotic skincare?

Probiotic skincare is skincare products with live probiotic bacteria. They contribute to and preserve the diversity of the skin microbiome, which is essential for maintaining the balance and natural immune system of the skin.

At the same time, the lactic acid bacteria control the pH of the skin at around 4.5. This allows the beneficial Lactobacillus bacteria to thrive, while it becomes too acidic for most "bad" bacteria, which therefore cannot survive.

Most so-called probiotic skincare contain lysates (dead bacteria). Keeping the bacteria alive requires careful formulation and Bak Probiotic Skincare is one of the few brands that know how to do this.


To indicate the amount of live bacteria in a product, the term CFU (Colony Forming Units) is used. The amount of CFU is stated per milliliter and is a measure of the product's ability to actively influence the skin's microbiome. The number should be in millions - the higher the CFU, the more active the product.

Live bacteria versus lysates

Usually, when the term probiotics is used, it concerns live microorganisms that have a beneficial effect on our body. In cosmetics, however, "probiotics" is used to describe products that do NOT contain live, probiotic bacteria. This is essential to know, because there is a big difference in what to expect from a product with live bacteria - and a product that "only" contains substances produced by probiotic bacteria, for example, lysates. Lysates may still have some useful effects, but not at the same level as live bacteria. Only live bacteria can actively influence and balance the microbiome composition.

Probiotic bacteria are naturally present on the skin and form an important part of its microbiome. Therefore, they are also very safe to use. When applied to the skin, they support and complement the natural bacterial diversity of the microbiome and can improve and restore its natural balance and health. The skin knows them, so to speak, and can immediately benefit from them.

Probiotics in Bak Probiotic Skincare

It is important to know that there are countless variants of each type of bacterium, each with its own unique properties and functionalities. 

All bacteria belonging to the Lactobacillus plantarum specium share common characteristics, but there are a myriad of different strains of each type of bacterium, each of which also has very specific properties and functionalities.

Lactobacillus plantarum is the same type of lactic acid bacterium that you typically encounter in fermented foods and in probiotic food supplements. The exact strain used in the Bak Probiotic Skincare products - the patented Lactobacillus plantarum LB244R - has been identified, selected and cultivated by Lactobio (the company behind the Bak Probiotic Skincare) for its unique and well-documented ability to inhibit the pathogenic (harmful) bacterium Staphylococcus aureus.

The specific strain Lactobacillus plantarum LB244R have a number of other benefits for the skin. This includes strengthening the skin's immune system by promoting the production of defensins (antimicrobial peptides), moisturising the skin, accelerating the natural renewal processes, promoting the rejection of dead skin cells and improving the barrier function of the skin by stabilising its Tight Junctions*. As a result, the skin will calm and become softer and smoother instead of dry, itchy and scaly.

*The so-called Tight Junctions in the upper layer of the skin (Stratum granulosum) are an important part of the barrier function. Tight Junctions holds the skin cells tightly together, preventing extraneous matter from penetrating the skin.


Use of probiotic skincare

To get all the benefits out of using probiotic skincare it requires a little effort. Traditional skincare products contain preservatives, but Bak Probiotic Skincare does not, as it would kill the contents of live bacteria. Therefore, the products with their fresh and natural ingredients are optimally stored in a refrigerator (4-6°C), but can also be stored at normal room temperature (25 °C). However, they should not be exposed to direct sunlight.

Shelf life after opening is approx. 4 months.
