Science
Mechanism of Action
This complex acts as a biochemical catalyst, biotransforming soy isoflavones into potent aglycones like Equol and Genistein to provide intense antioxidant protection. It works at the cellular level to stimulate the synthesis of ceramides and Natural Moisturizing Factors (NMF), while simultaneously regulating the skin's microbiome and inhibiting collagen-degrading enzymes (MMP-1).

Key findings
- 01 Clinical data demonstrates that 5% Streptococcus thermophilus lysate significantly elevates stratum corneum ceramide levels, leading to a measurable increase in hydration.
- 02 In-vitro fibroblast testing at 3% shows a marked stimulation of hyaluronic acid production and a reduction in transepidermal water loss (TEWL).
- 03 Fermentation studies confirm the conversion of soy glucosides into bioactive aglycones, enhancing anti-photoaging and antioxidant performance over standard soy extracts.

Dusting Analysis
Due to its high cost and long INCI name, this ingredient is frequently 'label-dusted' at concentrations below 0.5%. For genuine barrier repair and microbiome support, a minimum concentration of 1% to 3% is required to reach therapeutic efficacy.
The Formula
Formulation
Stability
Highly stable in aqueous systems and emulsions; however, it is heat-sensitive and should be added during the cooling phase (below 40°C) to maintain the integrity of its bioactive peptides.
