Science
Mechanism of Action
The efficacy of Prunus Spinosa Fruit Extract is attributed to its high concentration of bioactive polyphenols, including anthocyanins, phenolic acids, and flavonoids. These compounds act as powerful antioxidants, effectively neutralizing free radicals and mitigating oxidative stress within the skin. It also exhibits anti-inflammatory effects by modulating cellular responses, contributes astringent and tonic properties, and demonstrates broad-spectrum antimicrobial activity. Additionally, the extract has been shown to support the skin's natural wound healing processes.

Key findings
- 01 Demonstrated a marked antihemolytic effect, inhibiting hemolysis by 84% in pretreated cells exposed to oxidative stress, showcasing significant protective capabilities.
- 02 Achieved an antihemolytic EC50 (half maximal effective concentration) against oxidative stress, indicating a potent antioxidant capacity at a lower dose.
- 03 Inhibited the growth of several Gram-negative (Escherichia coli, Salmonella typhimurium, Enterobacter aerogenes) and Gram-positive (Enterococcus faecalis, Staphylococcus aureus) bacteria by over 50%.
- 04 Its anti-inflammatory properties were observed to enhance wound healing closure by 70% in human umbilical vein endothelial cells (HUVECs).

Stability
Anthocyanins, the primary active components, are chemically unstable and prone to oxidative degradation, influenced by factors such as pH, temperature, light, and oxygen. Optimal stability for these compounds is generally found in an acidic pH range. Formulation strategies like polymer entrapment (e.g., SLN, ethosomes, cubosomes) can significantly enhance the delivery and stability of the extract's cosmetic agents. Freezing the fruit prior to extraction is also identified as an optimal preservation method to maintain its antioxidant activity.
Safety
Safety Profile
