Science
Mechanism of Action
PIPER LONGUM FRUIT Extract contains key active compounds, including piperine and piperlongumine. Piperine can stimulate skin pigmentation by enhancing melanocyte proliferation through protein kinase C stimulation. Conversely, other components within the extract have demonstrated significant melanin inhibition, contributing to a skin brightening effect. Beyond pigmentation modulation, the extract exhibits strong antioxidant activity by inhibiting superoxide dismutase (SOD) and activating catalase (CAT). It also possesses anti-inflammatory properties, improves skin microcirculation for enhanced nutrient delivery and waste removal, and provides antimicrobial and antifungal benefits.

Key findings
- 01 Aqueous piperine extract stimulated mouse melanocyte culture growth by approximately 300% within 8 days, indicating potential for restoring skin pigmentation.
- 02 Piper Longin demonstrated a skin whitening effect through melanin extraction, with 0.005% showing comparable inhibition to 0.005% arbutin and suggesting a 500-fold superior effect on melanin inhibition.
- 03 Ethyl acetate extract of Piper longum fruit spike showed 89.7% superoxide dismutase (SOD) inhibition (EC50 = 1.23%) and dose-dependent activation of catalase (CAT) activity, signifying strong antioxidant properties.

Stability
Specific pH ranges for optimal stability were not identified. Extracts can be prepared using a variety of solvents, including water, ethanol, methanol, acetone, and ethyl acetate, indicating solubility in both aqueous and organic phases. Polyphenols, key active components, tend to extract more effectively in organic solvents. Certain extracts are noted to be soluble in both ethanol and water.
Safety
Safety Profile
Formal safety assessments by CIR or SCCS for cosmetic use are currently unavailable. While some sources suggest that Piper Longin is safe for topical use in small amounts, this is not a comprehensive safety evaluation. It is important to note that oral intake of isolated piperine at high doses (10-20 mg/Kg body weight) has been associated with reproductive toxicity and eye irritation, but these findings pertain to oral ingestion of isolated compounds, not topical application of the fruit extract.
