Science
Mechanism of Action
This extract operates by strengthening the epidermal barrier and substantially increasing skin hydration and moisture retention, partially through the stimulation of hyaluronic acid and glycosaminoglycan production. It actively promotes collagen synthesis, which contributes to improved skin elasticity. The ingredient demonstrates antioxidant properties, offering protection against cellular damage from free radicals, and exhibits anti-inflammatory effects that can effectively reduce redness and irritation. Furthermore, it helps modulate the skin's microbiome by providing antimicrobial actions against undesirable bacteria and fungi, potentially mitigating acne and blemishes. It also stimulates skin regeneration and cell renewal, leading to a refined skin texture. The fermentation process breaks down complex molecules into simpler, more absorbable forms, enhancing dermal penetration and concentrating vital nutrients such as vitamins and amino acids. Broader categories of Lactobacillus ferment may also contribute to DNA repair enzyme activity.

Stability
The extract exhibits stability in aqueous solutions within a pH range of 5.5 to 10.0, typically at 25°C for at least 24 hours; however, it demonstrates lability below pH 5.0. The fermentation process inherently lowers the pH of the extract, generally enhancing its compatibility with the skin's natural acidic mantle.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Lactobacillus Ferment, including Lactobacillus/Soybean Ferment Extract, is safe for use in cosmetics. It is generally well-tolerated and has received approval as a safe cosmetic additive within the European Union. While serious adverse effects are rare, individuals with known sensitivities to soy products are advised to perform a patch test prior to widespread use, as localized allergic reactions or irritation may occur.
