What Is Lactobacillus/Aspergillus/Prunus Mume Fruit Ferment Filtrate?
Lactobacillus/Aspergillus/Prunus Mume Fruit Ferment Filtrate comes from the ume fruit, a small plumlike fruit long valued in East Asia for food and traditional beauty rituals. Cosmetic makers mash ripe Prunus mume fruit then let two friendly microbes, Lactobacillus and Aspergillus, ferment the mash. During this natural process the microbes break down sugars and fruit acids into skin-loving compounds such as amino acids, mild organic acids, and antioxidants. After the ferment reaches the right activity level the mixture is carefully filtered, leaving a clear liquid rich in these helpful molecules while removing the solid pulp and live microbes.
Using fermented fruit extracts in skin care grew popular with the rise of Korean and Japanese beauty lines that favor gentle yet effective plant based ingredients. Brands noticed that the filtrate soothed skin and improved the feel of creams and serums, so it soon appeared in global formulas.
Today you can spot Lactobacillus/Aspergillus/Prunus Mume Fruit Ferment Filtrate in hydrating toners, sheet masks, lightweight essences, anti-aging serums, daily moisturizers, after-sun gels and even scalp mists. Its mild nature makes it easy to blend with other actives and suitable for both rinse-off and leave-on products.
Lactobacillus/Aspergillus/Prunus Mume Fruit Ferment Filtrate’s Cosmetic Benefits/Uses
This ferment filtrate is prized mainly for one key role in skin care formulas.
Skin conditioning: The blend of amino acids, natural sugars, and gentle acids in the filtrate helps soften and smooth the skin surface, leaving it feeling hydrated and fresh. It supports the skin barrier, adds a light refreshing finish to products, and can boost overall comfort in formulas aimed at calming or revitalizing tired looking skin.
Who Can Use Lactobacillus/Aspergillus/Prunus Mume Fruit Ferment Filtrate
The ferment filtrate is gentle enough for most skin types. Normal, dry, sensitive, oily and combination skin can all benefit from its light hydration and soothing feel. Because it is water based and free of heavy oils it will not weigh down oily or acne prone skin, while the amino acids and natural sugars add a soft boost of moisture that dry or mature skin often appreciates. There are no known reasons for it to be unsuitable for any specific skin type, though people with confirmed fruit or fermented ingredient allergies should stay cautious.
The ingredient is produced from fruit and microorganisms, with no animal derived compounds used in the process, so it is typically acceptable for vegans and vegetarians. It also aligns with many clean beauty and cruelty free standards, although shoppers should always verify the finished product’s certification if that is important to them.
Pregnant or breastfeeding women can usually use products containing this filtrate, as no data suggests it poses a risk when used on skin. That said this is not medical advice and anyone who is pregnant or nursing should show their healthcare provider any new skincare they plan to apply, just to be safe.
The filtrate does not increase photosensitivity, so it should not make skin more prone to sunburn. Daily sunscreen is still a smart idea for overall skin health.
Potential Side Effects/Adverse Reactions
Responses to topical Lactobacillus/Aspergillus/Prunus Mume Fruit Ferment Filtrate differ from person to person. The points below outline potential but uncommon reactions. When the ingredient is formulated and preserved correctly most users will not notice any problems.
- Mild stinging or redness temporary tingling can occur on very sensitive or compromised skin
- Allergic contact dermatitis rare but possible in individuals allergic to plum family fruits or fermentation byproducts
- Eye irritation if the product accidentally gets into the eyes it may cause watering or discomfort
- Breakouts though unlikely a few users may notice clogged pores if the surrounding formula contains heavier oils or waxes their skin dislikes

Comedogenic Rating
Rating: 0 (non-comedogenic)
This filtrate is water based and contains virtually no lipids or heavy film-forming agents that could block pores so it earns the lowest possible comedogenic score. Its small molecules are quickly absorbed or evaporate without leaving residue.
Because of this it is usually a safe choice for people who are prone to acne or breakouts.
Keep in mind that the finished product formula matters most; rich oils, waxes or silicones paired with the ferment could still trigger congestion even though the ferment itself does not.
Summary
Lactobacillus/Aspergillus/Prunus Mume Fruit Ferment Filtrate conditions skin by delivering lightweight hydration, smoothing rough patches and supporting a healthy barrier. Fermentation breaks ume fruit components into amino acids, gentle organic acids, sugars and antioxidants that bind water to the skin surface, calm minor irritation and leave a soft refreshed feel.
Thanks to the surge of interest in K-beauty and fermented botanicals the ingredient pops up in more toners, essences and moisturizers each year, though it is still less common than classics like aloe or green tea.
Overall it is considered very safe with a low risk of irritation or pore clogging. As with any new skincare step it is wise to do a small patch test first to rule out personal sensitivities.
