ASPERGILLUS/LACTOBACILLUS/RICE SEED FERMENT FILTRATE.

Valuable / SKIN CONDITIONING, SKIN CONDITIONING - EMOLLIENT

A high-performance bio-ferment produced through a multi-stage enzymatic breakdown of rice seeds by Aspergillus and Lactobacillus microorganisms. This process transforms traditional rice proteins into a concentrated elixir of bioavailable peptides and organic acids designed to optimize skin barrier health and luminosity.

Humectant Skin-conditioning agent Antioxidant Barrier repair Brightening

Science

This dual-ferment acts as a biological messenger, upregulating the expression of Aquaporin-3 (AQP3) and filaggrin to improve cellular water transport and barrier structural integrity. Simultaneously, it provides enzymatic inhibition of tyrosinase to brighten the complexion and utilizes fermented polyphenols to neutralize oxidative stress.

Key findings

  1. 01 Clinical data indicates a 1.25% concentration significantly enhances hydration and skin barrier proteins including AQP3 and filaggrin.
  2. 02 Research shows that while 0.5% provides modest collagen gene support, it acts as a powerful catalyst for collagen synthesis when paired with sialic acid, reaching nearly 200% efficacy.
