Science

Mechanism of Action

LACTOBACILLUS/AVENA SATIVA FERMENT EXTRACT FILTRATE operates by fostering increased biodiversity within the skin's microbiome, thereby rebalancing its natural microflora. It scientifically fortifies the skin barrier, optimizes moisture retention through its humectant capabilities, and helps stabilize the skin's pH levels. Furthermore, its established antioxidant and antimicrobial properties offer protection against environmental damage, oxidative stress, and undesirable microorganisms, concurrently promoting cellular regeneration and visibly calming irritation and redness.

Key findings

  1. 01 Usage levels of 1-2% are recommended to support a healthy skin microbiome, rebalance pH, protect against oxidative and DNA damage from environmental stressors, provide smoothing effects, and boost skin radiance by stimulating cell regeneration (Oat Cosmetics, aurafirm P technical documents).
  2. 02 Topical application has demonstrated a reduction in signs of sensitivity, such as stinging and itching, alongside enhanced hydration and protective effects against pollution and oxidative stress (Nu Allumé, for Lactobacillus Ferment Filtrate).
  3. 03 In a 7-day study involving 15 volunteers with dry skin, aurafirm (Lactobacillus Ferment, Avena sativa (Oat) Kernel Extract) significantly improved complexion and radiance, increased epidermal and stratum corneum thickness and lamination, and rapidly decreased skin roughness, resulting in firmer and plumper skin (Oat Cosmetics, aurafirm technical document).

Sensitization risk Moderate

The CIR Expert Panel concluded that related Lactobacillus Ferment ingredients are safe for cosmetic use, with reported concentrations up to 5.6% in face and neck products. While the Avena Sativa component is generally gentle, the Lactobacillus Ferment component carries a noted risk of allergic reaction for sensitive skin, making a patch test advisable. The CIR also emphasizes that ingredients exhibiting tyrosinase-inhibiting effects should not be formulated in a manner that induces skin depigmentation, as this constitutes a drug effect.
