Ingredient review
Fermented Aloe & Resin Complex
INCI: LACTOBACILLUS/ALOE BARBADENSIS LEAF/LIQUIDAMBAR STYRACIFLUA FERMENT FILTRATE
A gentle fermented ingredient that may help soothe and condition skin, but research is still limited.
In plain English
This ingredient is made by fermenting aloe leaf and sweetgum resin with friendly bacteria (Lactobacillus). Fermentation can break down plant compounds into smaller pieces that skin may absorb more easily, and the process also creates natural acids and peptides that can support a healthy skin barrier. It's used in serums and toners for its soothing and conditioning properties.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A filtrate from a fermentation process using Lactobacillus bacteria, aloe leaf, and sweetgum resin. The bacteria break down the plant materials, producing a liquid rich in amino acids, enzymes, and organic acids.
How it works
When applied to skin, the fermentation byproducts may help gently exfoliate dead skin cells, support the skin's microbiome, and deliver soothing compounds from aloe and sweetgum. The organic acids (like lactic acid) can also help maintain a slightly acidic pH on the skin's surface.
Pros
Soothing potential
Aloe is well-known for calming irritation, and fermentation may enhance its soothing effects.
Microbiome-friendly
Lactobacillus fermentation can produce prebiotic-like compounds that support beneficial skin bacteria.
Cons and cautions
Limited research
Most evidence comes from studies on aloe or fermentation in general, not this exact blend.
Variable potency
The concentration of active compounds can vary between batches, making results less predictable.
Best for
- People with normal to combination skin looking for gentle conditioning
- Those interested in fermented skincare for microbiome support
Use caution if
- Individuals with known allergies to aloe or sweetgum resin
Usage tips
Safety summary
This ingredient is considered safe for topical use. The fermentation process uses food-grade bacteria, and the resulting filtrate is non-toxic and non-irritating for most skin types. As with any new ingredient, patch testing is recommended for those with sensitive skin.
Research notes
Research on aloe fermentation shows potential for enhanced antioxidant and soothing activity. However, specific studies on this exact blend are lacking. The safety of Lactobacillus ferments in cosmetics is well-established.
Common label clues
- Typical concentration
- 1–10% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU when used as directed.
- Common uses
- Serums, Toners, Essences, Moisturizers
- Environmental note
- Aloe and sweetgum are renewable plant sources; fermentation is a low-energy process compared to chemical synthesis.
Good to know
- Fermented ingredients often have a slightly acidic pH, which can help maintain skin's natural acid mantle.
- This ingredient is typically clear or slightly yellow and has a mild, earthy scent.
