Science
Mechanism of Action
This extract functions as an effective humectant, significantly elevating skin moisture levels by attracting and retaining water. Its multifaceted action extends to bolstering collagen synthesis by up to 35% in vitro, simultaneously safeguarding existing collagen from degradation. This dual functionality contributes to a re-densifying effect, resulting in visibly smoother and less wrinkled skin. Enriched with essential vitamins and antioxidants, it offers robust protection against free radical damage and supports epidermal repair, while also promoting cell renewal and exhibiting anti-inflammatory and skin protectant properties crucial for barrier maintenance.
