Science
Mechanism of Action
HIBISCUS ROSA-SINENSIS FLOWER POWDER functions through multiple pathways to improve skin health. Its rich content of antioxidants, including anthocyanins and polyphenols, effectively neutralizes free radicals, thereby mitigating oxidative stress and combating premature aging. Natural alpha hydroxy acids (AHAs) facilitate gentle exfoliation, accelerating cell turnover, removing dead skin cells, and aiding in the reduction of hyperpigmentation for a refined skin texture. The presence of mucilage provides significant hydration by drawing and retaining moisture. Additionally, it exhibits anti-inflammatory properties that calm redness and irritation, and supports the synthesis of new collagen while inhibiting elastin degradation, which collectively contributes to enhanced skin firmness and elasticity. The ingredient also possesses antibacterial qualities, assisting in pore decongestion and reducing acne-related bacteria.
