Science
Mechanism of Action
This ingredient functions through multiple pathways to support skin health. It provides robust antioxidant protection, effectively neutralizing free radicals and reducing oxidative stress. Key compounds like resveratrol and quercetin stimulate collagen production, which consequently improves skin elasticity and firmness and aids in diminishing the appearance of fine lines. It also promotes improved microcirculation, contributes to skin cell regeneration, and fortifies the skin's moisture barrier against environmental stressors. Furthermore, it demonstrates a balancing effect, helping to regulate sebum production in oily complexions while delivering essential moisture to dry skin. Notably, it stimulates melanin synthesis by activating plasma membrane receptors MC1R and upregulating the transcript expression of MITF and tyrosinase, impacting both skin and hair pigmentation.

Safety Profile
Generally considered safe for topical application at lower concentrations. However, a patch test is highly recommended for individuals with sensitive skin due to documented instances of allergic reactions such as rashes and itching. Regulatory bodies, including the FDA, have not yet established specific guidelines for its use in cosmetics. It is important to note that oral consumption of Polygonum multiflorum has been associated with hepatotoxicity, but this concern does not directly apply to topical skincare formulations.
