Science

Mechanism of Action

Rosa Multiflora Extract exerts its effects through a multifaceted approach. Its high concentration of Vitamin C, quercetin, lycopene, flavonoids, and polyphenols provides potent antioxidant capabilities, neutralizing reactive oxygen species (ROS) and thereby protecting skin from UV-induced photoaging. It actively suppresses the production of proinflammatory cytokines (IL-6, IL-8, TNF-alpha) and matrix metalloproteinases (MMP-1, MMP-13), key contributors to skin degradation. Furthermore, it demonstrates anti-inflammatory action by inhibiting iNOS and COX-2. Evidence suggests an AMPK-dependent mechanism helps in mitigating oxidative stress, promoting autophagy, protecting against cellular senescence, and maintaining skin health under stress. The extract also contributes to collagen synthesis and aids in reducing the appearance of dark spots and hyperpigmentation.

Key findings

  1. 01 Effective at a 1-3% concentration in liquid formulations for reducing visible signs of photoaging (sun damage).
  2. 02 Ethanol extract of Rosa multiflora flowers provided protective effects against UV-induced photoaging in skin cells (keratinocytes, dermal fibroblasts) and hairless mice by suppressing ROS generation, proinflammatory cytokine production (IL-6, IL-8, TNF-alpha), and matrix metalloproteinase expression (MMP-1, MMP-13).
  3. 03 Rosa multiflora root extract topically improved atopic dermatitis-like skin lesions in mice by suppressing iNOS and COX-2 mRNA levels and reducing Th2 immune responses via IL-10 up-regulation.
  4. 04 Water, hexane, and ethyl acetate fractions of R. multiflora fruit extract demonstrated significant DPPH radical scavenging activity (up to 82.93%), with the ethyl acetate fraction showing greater activity than BHT.
