What Is Kluyveromyces/Lactobacillus/Plumeria Alba Flower Oil Ferment Filtrate?
Kluyveromyces/Lactobacillus/Plumeria Alba Flower Oil Ferment Filtrate is a skin care ingredient that starts with the fragrant blooms of the Plumeria alba tree, better known as frangipani. The flower’s oil is put through a gentle fermentation process using two well known microorganisms, Kluyveromyces yeast and Lactobacillus bacteria. During fermentation the microbes break down large oil molecules into smaller, more skin friendly components and generate new by-products such as organic acids, peptides and antioxidants. After the ferment is complete the mixture is filtered, leaving behind a clear liquid rich in these beneficial compounds.
Frangipani has long been prized in tropical regions for its scent and soothing feel, but it is the rise of Korean and Japanese ferment technology that pushed this ingredient into modern cosmetics. Brands began seeking gentler, bioactive alternatives to raw plant oils, and fermented extracts fit the bill.
The filtrate is produced in a controlled lab setting. First, pure Plumeria alba flower oil is mixed with a nutrient solution and inoculated with the selected yeast and bacteria. The mixture ferments at warm, stable temperatures for several days. It is then passed through fine filters to remove any solid residues and microorganisms, yielding a lightweight, water soluble liquid that blends easily into a wide range of formulas.
You will often spot this ferment filtrate in hydrating essences, brightening serums, leave-on masks, lightweight moisturizers and anti-aging concentrates where it can deliver its protective and balancing perks without a greasy feel.
Kluyveromyces/Lactobacillus/Plumeria Alba Flower Oil Ferment Filtrate’s Cosmetic Benefits/Uses
This multitasking ferment brings two main advantages to skin care products:
- Antimicrobial: The organic acids and peptides created during fermentation can help curb the growth of harmful surface bacteria. In a formula this supports a cleaner product environment and may assist in keeping blemish-prone skin calm and balanced.
- Antioxidant: Fermentation boosts the level of natural antioxidant compounds that neutralize free radicals formed by UV light and pollution. When added to creams or serums the filtrate helps defend skin against premature signs of aging such as dullness and fine lines.
Who Can Use Kluyveromyces/Lactobacillus/Plumeria Alba Flower Oil Ferment Filtrate
This ferment filtrate is lightweight and water based so it suits nearly every skin type, including oily, combination, dry and sensitive skin. Its antimicrobial and antioxidant properties make it especially handy for those prone to breakouts or early signs of aging. There are no known elements in the filtrate that would typically clog pores or leave a greasy film, which keeps it friendly for acne-prone complexions.
The ingredient is produced from plant flower oil and microorganisms, with no animal-derived matter involved, so it is generally considered suitable for vegans and vegetarians as long as the finished product is certified cruelty free.
No specific contraindications have been flagged for pregnant or breastfeeding women, and the ingredient is used at low concentrations in over-the-counter formulas. That said, this is not medical advice and anyone who is pregnant or nursing should run any skin care product past a qualified doctor to be on the safe side.
The filtrate does not increase sun sensitivity and can be used both morning and night without heightened risk of UV-related irritation. It also plays well with most common actives like niacinamide, vitamin C and peptides, making it easy to slot into an existing routine.
Potential Side Effects/Adverse Reactions
Individual responses to topical Kluyveromyces/Lactobacillus/Plumeria Alba Flower Oil Ferment Filtrate can differ, and the points below outline possible but uncommon reactions. When the ingredient is incorporated correctly into a finished product most users will not experience these issues.
- Mild stinging or redness in very sensitive skin, often transient
- Allergic contact dermatitis for those with specific sensitivities to fermented ingredients or floral components
- Dry or tight feeling if used in a formula with high levels of exfoliating acids that further lower skin pH
- Eye irritation if the product accidentally gets into the eyes
If any persistent discomfort, rash or swelling occurs discontinue use immediately and seek advice from a dermatologist or healthcare professional.
Comedogenic Rating
Rating: 0 / 5
Kluyveromyces/Lactobacillus/Plumeria Alba Flower Oil Ferment Filtrate is almost entirely water soluble, contains very little residual fatty matter and is used at low concentrations. These qualities mean it does not sit on the skin or block pores, so it earns the lowest spot on the comedogenic scale.
That makes it a safe pick for people who are prone to acne or frequent breakouts.
One thing to note: the overall formula still matters. If the filtrate is paired with heavy oils or waxes the finished product could be more pore clogging even though this single ingredient is not.
Summary
Kluyveromyces/Lactobacillus/Plumeria Alba Flower Oil Ferment Filtrate delivers two main perks: it helps keep unwanted microbes in check and supplies antioxidant protection. Fermentation breaks down Plumeria alba flower oil into smaller acids peptides and polyphenols that can penetrate easily and neutralize free radicals while creating an environment less friendly to blemish causing bacteria.
Although not yet a household name the ingredient has been gaining traction in K-beauty style essences and lightweight serums where consumers look for gentle fermented actives.
Current safety data and real-world use suggest the filtrate is well tolerated with a low risk of irritation or pore blockage. As with any new skin care addition a quick patch test is still wise to confirm personal compatibility.
