Science

Mechanism of Action

LACTOBACILLUS/ALGAE EXTRACT FERMENT operates by strengthening the skin's inherent microbiome, fostering a balanced microbial ecosystem critical for skin health. Its fermentation byproducts include antimicrobial peptides, which offer defense against environmental aggressors and maintain skin equilibrium. The ingredient significantly enhances skin hydration and resilience, thereby supporting a robust skin barrier function. Furthermore, it acts as an antioxidant, neutralizing free radicals, and contributes to skin brightening and reduction of hyperpigmentation through tyrosinase inhibition. The algae component provides additional humectant properties, leading to smoother and more supple skin, while also promoting cellular renewal.

Key findings

  1. 01 At 5% concentration, Lactobacillus Ferment demonstrated superior anti-acne efficacy, reducing lesion size and redness more rapidly than salicylic acid.
  2. 02 A 1% concentration of Lactobacillus Ferment significantly reduced skin sensitivity.
  3. 03 Studies indicate that Lactobacillus ferment metabolites effectively inhibit tyrosinase, contributing to reduced hyperpigmentation, even skin tone, and increased luminosity.
  4. 04 Lactobacillus ferment ingredients are shown to enhance skin hydration by elevating moisture levels.
  5. 05 An in vitro study confirmed a Lactobacillus rhamnosus spent-culture supernatant achieved 72.1% inhibition of tyrosinase activity.
  6. 06 A 4-week clinical evaluation on 24 healthy female subjects using a cream with Lacticaseibacillus rhamnosus ferment lysate on damaged skin reported no irritation.

Stability

For optimal stability, store LACTOBACILLUS/ALGAE EXTRACT FERMENT at room temperature, ideally not exceeding 25°C, in a tightly sealed container. This ingredient functions as a natural antimicrobial agent, capable of creating an unfavorable environment for harmful microbes, thus extending product shelf life. However, for a comprehensive preservation system, it may require synergy with pH control or additional co-preservatives.

Safe as used
Max tested
5.6%
Sensitization risk Moderate

The CIR Expert Panel has concluded that related Lactobacillus Ferment ingredients are 'safe as used' in cosmetics, with a reported maximum concentration of 5.6% in face and neck products. However, the specific INCI 'LACTOBACILLUS/ALGAE EXTRACT FERMENT' was designated with a retired status in 2015. EWG also raises potential concerns regarding high contamination levels (e.g., iodine, arsenic, lead) for this specific ingredient, which necessitates stringent quality control. For sensitive individuals, a preliminary patch test is advised due to a noted potential for allergy or irritation.
