Unlock Radiant Skin with DropCare® SRF: A Multi-Benefit Natural Ferment Ingredient

In the evolving world of skincare, natural and fermented ingredients continue to gain attention for their gentle yet effective properties. DropCare^® SRF (Saccharomyces/Rice Ferment Filtrate) is one such innovative ingredient that stands out for its remarkable skin benefits. Sourced from rice fermented with yeast, this powerful filtrate is rich in sugars, organic acids, amino acids, and other bioactive compounds that promote healthier, brighter, and more hydrated skin.

🔬 What is DropCare^® SRF?

DropCare^® SRF is a carefully formulated ingredient containing:

• Saccharomyces/Rice Ferment Filtrate

• Water

• Trehalose

• Xanthan Gum

• Hydroxyacetophenone

• 1,2-Hexanediol

This blend is designed to support skin barrier function, enhance brightness, and provide long-lasting hydration. It is recommended for use at concentrations between 0.5% to 20% in various cosmetic formulations.

🌿 Key Benefits & Scientific Evidence

1. Reinforces Skin Barrier

The skin’s barrier function relies heavily on proteins like Claudin-1, Claudin-4, and Occludin, which form tight junctions between cells. Studies have shown that DropCare® SRF significantly upregulates the expression of these proteins, strengthening the skin barrier without promoting cell proliferation. This effect is comparable to that induced by high calcium ion concentration, a known booster of tight junction formation.

2. Brightening & Whitening

Clinical tests involving human volunteers demonstrated that formulations containing DropCare® SRF led to a noticeable increase in skin luminance (L* value) and Individual Typology Angle (ITA° value). Results were statistically significant after just one week of use, with continued improvement over four weeks. The brightening effect was clearly distinguishable from the base formula, confirming the efficacy of the rice ferment filtrate.

3. Intense Hydration

DropCare^® SRF also excels in boosting skin moisture levels. Measured via skin moisture content (MMV), the ingredient showed a positive trend throughout the four-week trial, outperforming the base group. By the fourth week, the difference was significant, proving its ability to enhance skin hydration effectively.
