INCI: KLUYVEROMYCES/LACTOBACILLUS/PLUMERIA ALBA FLOWER OIL FERMENT FILTRATE
A gentle, fermented botanical oil that may help calm irritation and support a healthy skin barrier.
In plain English
This ingredient is made by fermenting plumeria (frangipani) flower oil with beneficial yeast and bacteria. Fermentation breaks down the oil into smaller, potentially more skin-friendly components. It is used in skincare to help soothe redness and keep the skin feeling soft and comfortable.

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 obtained after fermenting plumeria flower oil with Kluyveromyces (a yeast) and Lactobacillus (a probiotic bacteria). The fermentation process creates a complex mixture of fatty acids, peptides, and other bioactive compounds.
How it works
The fermentation process may enhance the oil's ability to support the skin's microbiome and reduce inflammation. The resulting filtrate is thought to help calm irritated skin and reinforce the skin's natural moisture barrier.
Pros
Gentle soothing
May help calm redness and irritation without harsh chemicals, making it suitable for sensitive skin.
Microbiome-friendly
The fermentation process can produce prebiotic-like compounds that support beneficial skin bacteria.
Cons and cautions
Limited evidence
There are few peer-reviewed studies on this specific ferment, so its benefits are based on traditional use and ingredient logic rather than robust clinical data.
Potential allergen
Plumeria is a botanical, and individuals with plant allergies may react to this ingredient.
Best for
- People with sensitive or reactive skin
- Those looking for probiotic skincare benefits
Use caution if
- Anyone with a known allergy to plumeria or frangipani
- Those who prefer non-fermented ingredients
Usage tips
Safety summary
This ingredient is considered safe for topical use. The fermentation process reduces the risk of irritation compared to the raw oil. As with any botanical, patch testing is recommended for those with sensitive skin or plant allergies.
Research notes
Direct studies on this specific ferment are scarce. However, research on Lactobacillus and Kluyveromyces ferments in skincare suggests they can support skin barrier function and reduce inflammation. Plumeria oil itself has traditional use as a soothing agent.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Generally recognized as safe for cosmetic use in the US and EU, with no specific restrictions.
- Common uses
- Serums, Moisturizers, Face Oils
- Environmental note
- Plumeria flowers are widely cultivated and not considered endangered. The fermentation process is relatively low-energy compared to chemical synthesis.
Good to know
- Fermentation can reduce the pore-clogging potential of some oils, making this a lighter option than raw plumeria oil.
- This ingredient is often found in 'clean beauty' products due to its natural origin and gentle processing.
