Science

Mechanism of Action

Citrus Aurantium Flower Oil actively benefits the skin through several mechanisms. It functions as a potent antioxidant, neutralizing free radicals to mitigate premature aging and cellular damage. Its anti-inflammatory capabilities reduce skin irritation, redness, itching, and sensitivity. The oil also exhibits antimicrobial and antifungal activities, which can help in reducing acne breakouts and inhibiting the proliferation of bacteria, yeast, and fungi. Furthermore, it promotes skin regeneration and cell turnover, thereby enhancing elasticity and diminishing the visibility of scars, stretch marks, fine lines, and wrinkles via a cytophylactic process. Astringent properties assist in regulating sebum production and refining pore appearance, while its natural humectant qualities contribute to skin hydration and moisture retention.
