What Is Lactobacillus/Erigeron Annuus Ferment Extract Filtrate?
Lactobacillus/Erigeron Annuus Ferment Extract Filtrate is a skin care ingredient produced by fermenting the entire Erigeron annuus plant with beneficial Lactobacillus bacteria. Erigeron annuus, sometimes called annual fleabane, is a flowering plant rich in flavonoids, sugars and small amounts of natural acids. During fermentation the bacteria break down the plant’s larger molecules into smaller, more skin-friendly compounds and increase the level of skin-loving substances like amino acids and peptides. Once fermentation is complete the material is filtered, leaving a clear liquid concentrate that slips easily into modern formulas.
The idea of using fermented botanicals in beauty started in East Asian skin care laboratories in the early 2000s when chemists noticed that traditional fermenting techniques could boost bioavailability and gentleness. Since then many brands have adopted similar extracts for their hydrating and soothing qualities. Today this filtrate shows up in lightweight essences, leave-on toners, sheet masks, daily moisturizers and assorted anti-age blends that aim to supply extra moisture without heaviness.
Lactobacillus/Erigeron Annuus Ferment Extract Filtrate’s Cosmetic Benefits/Uses
This fermented botanical primarily supports the skin’s moisture balance while offering conditioning benefits that make formulas feel smoother and more refreshing.
- Humectant: Draws water from the environment and the deeper layers of the skin toward the surface boosting immediate hydration and helping the complexion look plumper and more supple
- Skin Conditioning: Softens and smooths the skin surface improves texture and can enhance overall comfort especially in products designed for dehydrated or sensitive skin
Who Can Use Lactobacillus/Erigeron Annuus Ferment Extract Filtrate
This fermented extract is gentle, water based and non-oily so it suits most skin types including dry, normal, combination, oily and even sensitive complexions. Its lightweight humectant nature means it adds moisture without clogging pores making it a welcome addition for acne-prone users as well. There are no known concerns that make it unsuitable for any particular skin type, though extremely reactive skin should always proceed with extra caution when trying new formulas.
The ingredient is obtained from a plant that has been fermented with Lactobacillus, a naturally occurring bacterium, and contains no animal derived material or by-products. Because bacteria are microorganisms not classified as animals, products formulated with this filtrate are considered appropriate for both vegans and vegetarians as long as the overall formula is free of animal sourced additives.
No published data suggest that topical use of this filtrate poses a risk for women who are pregnant or breastfeeding. That said this information does not constitute medical advice and anyone who is expecting or nursing should check with a qualified healthcare provider before adding a new skincare product to their routine just to stay on the safe side.
The ingredient does not increase photosensitivity so there is no special daylight restriction beyond normal daily sunscreen recommendations. It also plays well with common actives such as niacinamide, hyaluronic acid and mild exfoliating acids so formulators can slot it into a wide range of routines without worry.
Potential Side Effects/Adverse Reactions
Responses to any cosmetic ingredient can differ from person to person. The effects listed below are only potential outcomes and are unlikely for the average user when the product has been properly formulated and preserved.
- Mild skin irritation such as temporary redness or stinging
- Allergic contact dermatitis in users sensitive to plant extracts or probiotic ferment by-products
- Itchiness or small surface bumps in very reactive or compromised skin barriers
- Eye irritation if the product accidentally gets into the eyes
If discomfort or an unexpected reaction occurs stop using the product immediately and consult a healthcare professional
Comedogenic Rating
Rating: 0 / 5. Lactobacillus/Erigeron Annuus Ferment Extract Filtrate is a water based ferment with virtually no oil or wax content so it does not leave residue that can block pores. Its molecular weight is low thanks to fermentation which helps it absorb cleanly rather than sit on the surface. For these reasons it is considered non-comedogenic and is generally suitable for people who are prone to acne or breakouts.
Because the ingredient is often paired with other lightweight humectants it rarely alters the overall pore-clogging profile of a formula. Only if combined with richer oils or heavy silicones could the final product become more comedogenic.
Summary
Lactobacillus/Erigeron Annuus Ferment Extract Filtrate works mainly as a humectant and skin-conditioning agent. Fermentation breaks the plant into smaller molecules such as amino acids and sugars that pull water toward the skin improving hydration, softness and overall comfort without heaviness. Although not as famous as hyaluronic acid or glycerin the ingredient is gaining quiet popularity in K-beauty inspired essences, toners and gel moisturizers where light yet lasting moisture is valued.
Current data and real-world use show it to be very safe with a low risk of irritation or pore clogging. As with any new skincare item a short patch test is still wise to make sure your individual skin agrees before full-face use.
