ECKLONIA CAVA/SACCHARINA JAPONICA EXTRACT.

Valuable / ANTIOXIDANT

This potent marine extract, combining Ecklonia Cava and Saccharina Japonica, offers a multi-faceted approach to advanced skin health. Scientifically demonstrated to reduce cellular senescence markers for rejuvenation, it also provides significant antioxidant protection and deep moisturizing benefits, enhancing the skin's integral barrier function.

Antioxidant Skin-soothing Anti-aging Moisturizing Anti-inflammatory Anti-acne Barrier Reinforcement

Science

Mechanism of Action

Ecklonia Cava, rich in phlorotannins and polyphenols, functions as a robust antioxidant, neutralizing free radicals and safeguarding against oxidative stress and UV-induced damage. It possesses anti-inflammatory properties, reducing redness, and promotes collagen synthesis to visibly diminish fine lines and wrinkles. The extract downregulates matrix metalloproteinases (MMPs), enzymes responsible for extracellular matrix degradation, thereby contributing to anti-aging effects. It restores cellular viability, normalizes cell cycle distribution disrupted by urban pollutants, and strengthens the skin barrier by decreasing MMP-1 and increasing filaggrin expression. Saccharina Japonica (related to Laminaria japonica) enhances skin hydration through its humectant and hydrocolloid properties, drawing water to the stratum corneum and augmenting the skin's natural moisturizing factors.

Stability

Ecklonia Cava acetone fraction's anti-P. acnes activity was not significantly impacted by variations in temperature, pH, or exposure to artificial UV light or natural sunlight, indicating good stability. In emulsion products, Ecklonia Cava extract showed no change in appearance, color, or odor during stability testing. Laminaria japonica extract did not negatively affect the physicochemical characteristics of test cream formulations.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Low

The CIR Panel noted insufficient data for *related* brown algae-derived ingredients, not specifically for this combination. However, Ecklonia Cava extract (acetone fraction) demonstrated no cytotoxicity at 100 μg/mL and elicited negative reactions in patch tests. Similarly, Laminaria japonica extracts were found safe for human skin at moderate doses in patch tests, indicating a low irritancy potential. Pregnant or breastfeeding individuals should consult a healthcare provider.
