Science
Mechanism of Action
This extract functions through several key pathways. Its high concentration of vitamins (A, B, C, E, K) and antioxidants actively neutralizes free radicals, safeguarding dermal collagen and elastin from environmental damage and contributing to anti-aging effects. Natural enzymes, notably actinidin, alongside fruit acids, facilitate gentle exfoliation, promoting cellular renewal, refining texture, and clearing pores. Furthermore, its ability to modulate cytokine activity provides anti-inflammatory benefits, reducing redness and soothing irritated skin. Vitamin C content supports collagen synthesis for improved firmness, while demonstrated antibacterial and antimicrobial properties help to manage acne-causing bacteria and reduce associated inflammation. It also aids in skin brightening by addressing hyperpigmentation and enhancing overall tone.
