Science

Mechanism of Action

This extract functions effectively as a retinol-like ingredient, stimulating dermal metabolism and promoting Type I collagen synthesis. Concurrently, it inhibits metalloproteinases (MMP-1), enzymes implicated in collagen and elastin degradation, thereby preserving extracellular matrix integrity and reducing wrinkles. Rich in galactomannans, polyphenols, and coumarins, it delivers potent antioxidant properties that combat oxidative stress and protect against free radical damage. Its anti-inflammatory components soothe irritated skin and reduce puffiness. Furthermore, specific polysaccharide fractions promote epidermal cell differentiation, enhance tight junction formation, and increase procollagen synthesis, while B vitamins contribute to oil regulation and coumestrol offers photoprotective advantages.

Key findings

  1. 01 Demonstrated significant wrinkle reduction in vivo after 28 days of treatment, indicating potent anti-aging effects.
  2. 02 This range represents the typical use level in cosmetic formulations when supplied in a water-based blend, providing anti-aging and soothing benefits.
  3. 03 Increased keratinocyte viability to over 170% in vitro, suggesting enhanced cell regeneration and skin repair.
  4. 04 Triggered cornified envelope formation, increased gene expression of filaggrin and involucrin (promoting epidermal cell differentiation), enhanced tight junction formation (increased claudin1), and decreased LPS-induced proinflammatory cytokines in keratinocytes. In dermal fibroblasts, it increased procollagen synthesis and decreased elastase activity and metalloproteinase-1 (MMP) secretion, alongside exhibiting superoxide dismutase (SOD)-like antioxidant activity.
  5. 05 Showed 56.71% inhibition of free radicals in vitro, confirming its potent antioxidant capacity.
