KADSURA COCCINEA FRUIT EXTRACT.

Valuable / ANTIOXIDANT, SKIN CONDITIONING

Kadsura coccinea fruit extract, sourced from a traditional medicinal plant, is a potent botanical ingredient demonstrating significant photoprotective and anti-melanogenic properties. Rich in antioxidants like polyphenols and anthocyanins, it supports skin health by mitigating oxidative stress and addressing uneven skin tone.

Antioxidant Photoprotective Skin Brightening Anti-inflammatory

Science

Mechanism of Action

This extract functions as a multi-faceted agent against environmental stressors and hyperpigmentation. Its antioxidant activity, stemming from abundant polyphenols and anthocyanins, combats free radical damage. For photoprotection, it safeguards keratinocytes by enhancing their viability, reducing cellular damage (LDH release), limiting reactive oxygen species (ROS) production, and preventing apoptosis following UVA and UVB exposure. In terms of skin brightening, it precisely targets melanin synthesis in melanocytes by decreasing intracellular melanin content and inhibiting tyrosinase activity. Further, it downregulates the expression of key melanin-producing enzymes (tyrosinase, TRP-1, TRP-2) and associated regulatory factors (MITF, cAMP-response element-binding protein), offering a comprehensive approach to even skin tone. Additionally, its bioactive compounds, including lignans and flavonoids, contribute to its anti-inflammatory profile.

Key findings

  1. 01 In-vitro studies demonstrate that a 0.05% (0.5 mg/mL) concentration significantly enhances keratinocyte viability and reduces markers of cellular damage (LDH release, intracellular ROS, apoptosis) in UVA/UVB-irradiated cells, indicating robust photoprotective effects.
  2. 02 At a 0.05% (0.5 mg/mL) concentration, the extract effectively decreases intracellular melanin content and inhibits tyrosinase activity in α-MSH-stimulated melanocytes in vitro, confirming its anti-melanogenic capabilities.
