Science

Mechanism of Action

This extract operates through multiple pathways to enhance skin health. Its high concentration of polyphenols (including anthocyanins, flavonoids, and tannins), vitamin C, and other antioxidants such as ferulic acid, caffeic acid, and quercetin provides robust protection against free radical damage induced by environmental pollution and UV radiation. For anti-aging, it demonstrably upregulates elastin gene transcription and stimulates tropoelastin production, while simultaneously inhibiting elastase enzymes. This dual action supports enhanced collagen and elastin synthesis, improving skin tonicity and elasticity. Furthermore, it calms inflammation, exhibits bactericidal properties, and functions as an astringent due to tannins, which strengthen the skin barrier, minimize transepidermal moisture loss, constrict pores, and regulate sebum. The presence of fruit acids aids in gentle exfoliation, promoting cellular renewal and unclogging pores, while its hydrating properties and vitamin C content contribute to moisture retention and a more even, brightened skin tone.

Key findings

  1. 01 Effective in reducing DPPH radicals, indicating significant antioxidant activity, with an IC50 score of 34.29 ± 0.55 µg/mL dw.
  2. 02 Demonstrated strong inhibitory action against monoamine oxidase B (MAO-B), contributing to antioxidant effects, with an IC50 between 4 and 7 mg/mL.
  3. 03 Upregulates elastin gene transcription, stimulates tropoelastin production, and inhibits leukocyte and fibroblast-derived elastase activity, suggesting enhanced collagen and elastin synthesis for improved skin tonicity and elasticity.
