What Is Streptomyces Avermitilis/Soybean Extract Ferment Filtrate?
Streptomyces Avermitilis/Soybean Extract Ferment Filtrate is a liquid by-product collected after soybean extract is fermented with a friendly soil bacterium called Streptomyces avermitilis. The process starts with Glycine max seeds that are soaked then broken down to release proteins, sugars and minerals. When the microbe feeds on this nutrient mix it produces a broth rich in peptides, amino acids, antioxidants and small soothing molecules. Once fermentation is complete the mixture is filtered to remove solids and living cells leaving a clear stable filtrate suitable for skin care.
Fermented plant ingredients first gained attention in East Asia where beauty brands searched for milder yet effective actives. Researchers noticed that fermentation not only boosts antioxidant levels but also lowers the pH and size of the original molecules making them easier for skin to accept. Over time laboratory studies confirmed that Streptomyces avermitilis creates a filtrate with protective benefits so formulators began adding it to hydrating essences and calming creams.
Today you will most often see Streptomyces Avermitilis/Soybean Extract Ferment Filtrate in lightweight serums, anti-aging moisturizers, sheet masks and leave-on treatments aimed at dull tired or environmentally stressed skin. It blends well with hyaluronic acid, niacinamide and gentle plant oils helping brands create multifunctional products without heavy textures.
Streptomyces Avermitilis/Soybean Extract Ferment Filtrate’s Cosmetic Benefits/Uses
This ferment brings several useful actions to a formula.
- Antioxidant: The filtrate is packed with compounds that neutralize free radicals from UV light and pollution. This can help slow the look of premature aging such as fine lines and uneven tone.
- Skin conditioning: Fermentation breaks soy proteins into smaller peptides and amino acids that bind water and smooth the skin surface. Regular use leaves skin feeling softer and more supple.
- Skin protecting: By reinforcing the moisture barrier and calming oxidative stress the ingredient helps shield skin from daily irritants which can reduce redness and sensitivity over time.
Who Can Use Streptomyces Avermitilis/Soybean Extract Ferment Filtrate
This ferment filtrate suits most skin types including dry, oily and combination because it is lightweight and water based. Its soothing profile also makes it a good option for sensitive or redness-prone skin. The main group who should use caution are people with a known soy allergy since the ingredient comes from soybeans and trace proteins may remain.
The material is produced from plants and a soil bacterium, with no animal by-products, so it is considered both vegan and vegetarian friendly.
There are no reports of the filtrate affecting hormone levels or containing vitamin A derivatives, so pregnant or breastfeeding women can usually use it. This is not medical advice and anyone who is expecting or nursing should show the full product list to a doctor first to be safe.
Topical use does not make skin more sensitive to the sun, though daily sunscreen is still wise for overall skin health. The ingredient also plays well with most common actives and makeup, and it has a very low odor, so it blends nicely into simple or layered routines.
Potential Side Effects/Adverse Reactions
Reactions to topical Streptomyces Avermitilis/Soybean Extract Ferment Filtrate differ from person to person. The points below list potential issues, but most users will not experience them when a product has been made and stored correctly.
- Temporary redness or mild stinging on very sensitive skin
- Allergic response in individuals with a soy allergy
- Contact dermatitis from sensitivity to fermentation by-products
- Extra irritation if layered with strong acids or retinoids in the same routine
- Breakouts or infection if a poorly preserved formula becomes contaminated
If any of these effects appear stop use right away and seek help from a healthcare professional or dermatologist.
Comedogenic Rating
Rating: 0–1. Streptomyces Avermitilis/Soybean Extract Ferment Filtrate is a lightweight water based liquid without fatty acids or heavy oils so it is very unlikely to clog pores. Its small peptide and amino acid molecules absorb easily and do not form a film that traps sebum. For this reason it is generally considered safe for acne prone or congested skin. Only in rare cases where the finished product also contains comedogenic thickeners or oils could the risk rise.
Summary
Streptomyces Avermitilis/Soybean Extract Ferment Filtrate works as an antioxidant skin conditioner and skin protectant. Fermentation breaks soy proteins into tiny peptides that hydrate while boosting antioxidant compounds that fight free radicals and soothe environmental stress. These actions together help skin look smoother brighter and more resilient.
The ingredient is gaining traction in K-beauty style serums and masks yet it is still a niche choice compared with big names like niacinamide or hyaluronic acid. Brands that want a gentle fermented touch without strong acids often reach for it.
Overall safety is high with very low irritation reports apart from those with soy allergies. Still it is smart to do a quick patch test whenever you try a new product to catch any personal sensitivities early.
