LINDERA STRYCHNIFOLIA ROOT EXTRACT.

This extract confers multiple advantages to the skin, primarily through its robust antioxidant, anti-inflammatory, and hydrating capacities. Rich in polyphenols, linderane, and linderalactone, it effectively neutralizes reactive oxygen species (ROS) and reactive nitrogen species (NOS), thereby safeguarding skin and hair from oxidative stress and mitigating premature aging by inhibiting lipid peroxidation. Its anti-inflammatory properties soothe irritation and reduce redness. For scalp and hair, it specifically rebalances the microbial ecosystem (bacteriobiota and mycobiota), supporting healthy hair growth and addressing conditions like androgenetic alopecia (AGA) by decreasing unfavorable bacteria and increasing beneficial species. It also stimulates dermal papilla cell proliferation and upregulates growth factors like IGF-1 and VEGF. Furthermore, a specialized hydrolysate of the extract, abundant in oligo-α-glucans, has been shown to reactivate the CLOCK circadian gene in skin cells. This synchronization boosts dermal metabolic functions, leading to improved hydration, enhanced biomechanical properties, increased skin brightness, and a smoother microrelief, akin to the effects of light therapy.
