Mechanism of Action
Citrus Sunki Peel Extract improves skin health by acting as a conditioning agent and humectant, effectively minimizing transepidermal water loss and drawing moisture into the stratum corneum. It fortifies the skin's natural barrier, protecting against harmful substances, irritants, and pathogens that can lead to inflammatory conditions. Its rich composition of flavonoids, terpenes, linalool, vitamin C, and folic acid provides potent antioxidant benefits, evidenced by its DPPH radical scavenging and H2O2 reaction capabilities. Furthermore, the extract demonstrates anti-inflammatory action by reducing key inflammatory markers like IL-6 and TNF-α, and by suppressing nitric oxide production.
