What Is Leuconostoc/Aloe Barbadensis Leaf/Sorbus Aucuparia Fruit Ferment Filtrate?
Leuconostoc/Aloe Barbadensis Leaf/Sorbus Aucuparia Fruit Ferment Filtrate is a naturally derived ingredient made by letting the friendly microbe Leuconostoc ferment a blend of Aloe vera leaves and rowanberry (Sorbus aucuparia) fruit. During fermentation the plant sugars, proteins and minerals are broken down into smaller molecules such as peptides, amino acids and organic acids that are more easily absorbed by the skin. The final step is filtration, which removes the solid plant matter and leaves behind a clear nutrient rich liquid.
Fermented plant extracts first caught attention in Korean beauty where gentle yet effective ingredients were in high demand. Brands soon noticed that the process not only boosted skin benefits but also created light antimicrobial activity that could support product freshness. Today this filtrate appears in a range of cosmetic formulas seeking a clean label alternative to traditional preservatives.
Production starts with freshly harvested Aloe leaves and ripe rowanberries that are cleaned then pulped. The mash is mixed with water and a small amount of sugar to feed the bacteria, inoculated with Leuconostoc and kept at a controlled temperature for several days. Once the desired pH and active compound levels are reached the mixture is filtered, yielding a clear fluid ready for use.
You will most often find this ferment filtrate in hydrating face masks, soothing moisturizers, anti-aging serums, leave-in hair conditioners, scalp tonics, cuticle oils and other formulations where brands want a multitasking botanical that also helps keep the product stable.

The ingredient is completely plant and microbe derived so it fits the lifestyle choices of vegans and vegetarians. No animal sourced materials are used in the cultivation of the plants, in the fermentation itself or during filtration.
Current data shows no specific risks for women who are pregnant or breastfeeding when this ferment is applied topically in normal cosmetic concentrations. Absorption through intact skin is minimal yet this is not medical advice and anyone expecting or nursing should discuss all skincare products with a qualified healthcare professional for personal reassurance.
Leuconostoc/Aloe Barbadensis Leaf/Sorbus Aucuparia Fruit Ferment Filtrate does not make skin more sensitive to sunlight so it is not considered photosensitising. It also plays well with most common cosmetic actives and does not carry any known age or gender restrictions.

Comedogenic Rating
Rating: 0 / 5
This ferment filtrate is almost entirely water with trace amounts of organic acids and small peptides so it lacks the heavy oils or waxes that can clog pores. Its light texture is quickly absorbed and leaves no greasy residue which is why it earns a solid non comedogenic score of 0. As a result it is generally suitable for people prone to acne or breakouts.
The only caveat is that products combining this filtrate with richer emollients could change the overall pore clogging potential so always check the full formula if congestion is a concern.
Summary

The fermentation process breaks down Aloe and rowanberry nutrients into smaller bioavailable molecules that calm hydrate and protect the skin. At the same time the weak organic acids produced during fermentation help keep harmful microbes at bay enhancing product freshness.
Originally popularised by K beauty brands that spotlight fermented botanicals this ingredient is gaining steady but not blockbuster attention in mainstream skincare thanks to its clean label appeal and versatility. Current data shows it is well tolerated with a low risk of irritation making it safe for daily use in most people. As with any new cosmetic we still recommend a simple patch test before full application just to be sure your skin agrees with the formula.
