Science

Mechanism of Action

This ingredient functions by stimulating collagen type I production and inhibiting MMP-1 activity, which is responsible for the degradation of collagen and elastin, thereby acting as a gentle yet effective anti-aging agent. Rich in galactomannans and polysaccharides, it provides antioxidant protection against oxidative stress and supports the skin barrier by enhancing epidermal cell differentiation and tight junction formation. It also exhibits anti-inflammatory effects by decreasing proinflammatory cytokines, contributes to improved skin tone through chlorophyll, and offers photoprotective properties with coumestrol.

Key findings

  1. 01 Topical gel formulations containing Medicago sativa leaf extract significantly promoted wound healing in rats, evidenced by reduced epithelialization periods, improved wound contraction, and increased breaking strength in incision wounds.
  2. 02 In vitro studies demonstrated that alfalfa herb extract boosted keratinocyte viability by over 170%, with higher concentrations (above 2.5%) increasing fibroblast viability by approximately 150%.
  3. 03 An in vivo human study showed that a preparation containing Medicago Sativa Extract resulted in significant wrinkle reduction after 28 days compared to placebo, through stimulation of collagen I synthesis and inhibition of metalloproteinases.
