Science

Mechanism of Action

Cucurbita Maxima Seed Oil provides antioxidant defense through its rich profile of phenolic compounds, tocopherols (Vitamin E), and carotenoids, shielding skin from oxidative and UV-induced damage. Its high content of fatty acids, particularly linoleic and oleic acids, establishes a robust protective barrier, effectively reducing transepidermal water loss and preserving skin hydration and integrity. The oil exhibits anti-inflammatory and soothing properties, calming irritation and benefiting conditions like psoriasis and dermatitis, with linoleic acid specifically contributing to inflammation prevention. Furthermore, it supports anti-aging by stimulating collagen synthesis, enhancing skin elasticity, combating free radicals, and inhibiting key enzymes such as collagenase and hyaluronidase. Beyond this, the oil demonstrates antibacterial activity, supports wound healing through potential hemostatic effects and collagen stimulation, and nourishes the skin with essential minerals (magnesium, potassium, zinc, calcium, iron) and vitamins (C, E).
