What Is Aspergillus/Aloe Vera Leaf Ferment Filtrate?
Aspergillus/Aloe Vera Leaf Ferment Filtrate is a processed form of aloe vera that has undergone fermentation using Aspergillus fungi. During fermentation, beneficial compounds are broken down into smaller molecular fragments, which may enhance skin penetration and bioavailability compared to unfermented aloe.
The filtrate portion means the liquid has been separated from solid matter, creating a concentrated liquid ingredient. In skincare, it primarily functions as a humectant and conditioning agent, drawing moisture into the skin and helping to maintain hydration levels.
How It Works
Fermentation breaks down aloe vera's polysaccharides and other compounds into smaller, more easily absorbed molecules. This process can increase the ingredient's ability to penetrate the stratum corneum (outer skin layer) and deliver hydrating compounds more effectively than whole aloe leaf juice.
The ferment filtrate works primarily as a humectant — it attracts water molecules from the dermis (deeper skin layers) and the environment into the epidermis, plumping skin and reducing the appearance of dryness. It also contains compounds with potential anti-inflammatory properties, though more research is needed to establish efficacy at typical cosmetic concentrations.
Clinical Evidence & References
Evidence on this specific fermented derivative is limited. Most research focuses on whole aloe vera leaf juice or extract, which has demonstrated hydrating and mildly soothing effects in several studies. Fermentation theoretically improves bioavailability, but direct clinical comparison data between fermented and non-fermented aloe in skincare products is scarce.
The ingredient is generally recognised as safe in cosmetics and has a long history of traditional use. However, robust clinical trials specific to this ferment filtrate's efficacy at typical product concentrations remain lacking, so claims should be measured.
How to Use
This ingredient is typically found in serums, hydrating toners, and lightweight moisturisers. Apply to clean skin before heavier creams to allow hydration to penetrate. It works well layered with other humectants such as glycerol or hyaluronic acid for additive hydrating effect. No specific usage restrictions, though as with any new skincare product, patch test first if you have sensitive or reactive skin.
