Lactobacillus Ferment Lysate

Lactobacillus Ferment Lysate at a glance

Lactobacillus Ferment Lysate is a liquid made from lactic acid bacteria. The bacteria are grown in a nutrient medium and then broken open, a process called lysis. The resulting liquid contains cell wall fragments, peptides, polysaccharides and other cell components. It dissolves in water, contains no living bacteria and is added to the water phase during cool-down. Confirm the full INCI and dose on the certificate of analysis.

The postbiotic idea

Skin hosts a large community of microbes, often called the skin microbiome. Interest in this topic has made bacteria-derived ingredients very popular. Because living bacteria are hard to keep stable in a preserved cosmetic, the industry uses lysates and ferments instead. These are often called postbiotics. The lysate supports a balanced, comfortable skin feel and a smoother texture, and it fits brands that want a microbiome-friendly story.

Formats

Facial creams and serums

The main use is as a moisturizing and restoring component in daily creams and serums.

Care for problem-looking skin

Light gels and fluids that soothe the look of irritation and keep skin comfortable.

appearance-focused cosmetic care

Night creams and serums for smoother texture and a renewed look.

Toners and lotions

Light liquids that support a balanced feel after cleansing.

How to use it

Add the lysate to the water phase below 40 °C and stir until uniform. Choose a preservative system that is gentle on the skin, and keep the final pH between 5 and 6, close to the skin's own surface. Avoid harsh surfactants in the same product if the story is about a balanced microflora.

Partners

Microbiome-friendly products often add prebiotic sugars and barrier lipids. Ceramide NP supports the barrier story, and betaine adds a soft moisture feel. More concentrates are listed in the actives catalog.

Microbiome comfort cream recipe, 100 g

Distilled water 71.80 g, Lactobacillus Ferment Lysate 5.00 g, glycerin 4.00 g, caprylic/capric triglyceride 8.00 g, squalane 3.00 g, cetearyl olivate and sorbitan olivate 4.00 g, cetearyl alcohol 1.50 g, ceramide NP 0.20 g, xanthan gum 0.30 g, panthenol 1.00 g, phenoxyethanol and ethylhexylglycerin 1.00 g, tocopherol 0.20 g. Heat the water and oil phases to 75 °C, emulsify, cool to below 40 °C, add the lysate, panthenol and preservative, and adjust the pH to about 5.5.

Claim wording

Use wording such as microbiome-friendly, balanced, comfortable and smoother-looking. Avoid the word probiotic, which suggests living microbes, and avoid any wording that suggests the product fights bacteria or works on skin conditions. Microbiome-friendly claims are best supported by a test on skin flora diversity.

Dose guidance

Follow the technical sheet. Daily creams and serums use the recommended level.

Testing

Skin microflora swabs before and after four weeks of use, together with corneometer readings and comfort questionnaires, support balance and moisture wording.

Who it is for

Consumers with sensitive, reactive or easily stressed skin are the main audience. Many of them already avoid strong fragrance and harsh cleansers, and they want a short, gentle routine. A daily cream and a toner with the lysate fit that routine well.

Storage

Store tightly closed in a cool place. Keep the container clean and close it right after use.
