What Is Lactobacillus/Prunus Mume Fruit Extract Ferment Extract Filtrate?
Lactobacillus/Prunus Mume Fruit Extract Ferment Extract Filtrate is a skin care ingredient that comes from the Japanese apricot, also called Prunus mume. The fruit is first turned into an extract rich in natural sugars, organic acids and polyphenols. This extract is then fermented with the probiotic bacterium Lactobacillus. After fermentation the mixture is filtered, leaving behind a light liquid packed with skin-friendly metabolites such as peptides, amino acids and antioxidants.
Using fruit ferments in beauty products is not new, but interest in Korean and Japanese skin care helped bring this specific filtrate into the spotlight over the past decade. Brands were drawn to the idea of combining a traditional fruit known for vitality with modern probiotic science, giving consumers a story that feels both ancestral and cutting-edge.
Manufacturing starts with responsibly harvested Prunus mume fruit. The fruit is crushed and steeped in a food-grade solvent, usually water or a mild alcohol, to pull out its active compounds. Lactobacillus is then added and the mixture is kept at a controlled temperature so the bacteria can break down larger molecules into smaller, more skin-penetrating forms. Once fermentation reaches the desired point the liquid is passed through fine filters to remove solids and microbes, yielding a clear, stable filtrate ready for cosmetic use.
Because the filtrate is lightweight and water-soluble it fits easily into many formulas. You will often see it in hydrating toners, soothing essence lotions, sheet masks, brightening serums, daily moisturizers and anti-aging emulsions. It can also be added to rinse-off masks and after-sun gels where an extra antioxidant boost is welcome.
Lactobacillus/Prunus Mume Fruit Extract Ferment Extract Filtrate’s Cosmetic Benefits/Uses
This ferment filtrate is valued mainly for one key function that supports overall skin health.
Antioxidant: The filtrate delivers polyphenols from Prunus mume along with small peptides created during fermentation. Together they help neutralize free radicals generated by UV light and pollution. By cutting down oxidative stress the ingredient can aid in keeping skin tone even, supporting firmness and helping formulas market claims like “defends against premature signs of aging.”
Who Can Use Lactobacillus/Prunus Mume Fruit Extract Ferment Extract Filtrate
This ferment filtrate is gentle and water based, making it suitable for dry, normal, combination and oily skin alike. Its lightweight feel means it will not clog pores or add excess oil, while the soothing antioxidant profile offers comfort for dry or sensitive complexions. The only group that may need caution is anyone with a known allergy to stone fruits such as apricot or plum, as cross reactions, although rare, can occur.
The ingredient contains no animal derived material so it meets vegan and vegetarian standards. Lactobacillus used in cosmetic fermentation is cultured in plant based media and the Prunus mume fruit itself is botanical.
Pregnant or breastfeeding individuals are not expected to face unique risks from topical use of this ferment filtrate. Still, this is not medical advice and it is always best for expectant or nursing mothers to review any new skincare product with a qualified healthcare provider.
The filtrate does not make skin more sensitive to sunlight and can be used both morning and night without altering your usual SPF routine. It is also pH friendly and plays well with common actives like niacinamide, hyaluronic acid, retinoids and vitamin C.

If irritation or any unwanted reaction occurs stop use right away and seek advice from a medical professional
Comedogenic Rating
Rating: 0/5. This filtrate is water based and free of heavy oils or waxes that can block pores. Its small molecular weight peptides and sugars absorb quickly without leaving an occlusive film, keeping pore congestion unlikely. The fermentation process also breaks down larger compounds into lighter skin compatible forms that rinse or absorb cleanly.
Because of its zero rating the ingredient is generally suitable for people who are prone to acne or breakouts.
No data suggest it aggravates fungal acne, and it can fit comfortably into routines that rely on lightweight layers or active treatments.
Summary
Lactobacillus/Prunus Mume Fruit Extract Ferment Extract Filtrate serves mainly as an antioxidant. Fermentation releases polyphenols and creates micro peptides that mop up free radicals from UV light and pollution helping skin maintain an even tone and a firmer feel.
The ingredient enjoys modest popularity, especially in K-beauty inspired toners and essences where a clean water texture and a probiotic twist appeal to consumers looking for gentle daily defense.
Safety profiles are strong with low irritation risk and a non-comedogenic nature. As with any new skincare product it is wise to perform a quick patch test to make sure your skin agrees before moving to full-face use.
