Science
Mechanism of Action
This extract leverages its bioactive compounds to exert multiple positive effects. It acts as a potent antioxidant, neutralizing oxidative stress within skin cells. Its anti-inflammatory action is demonstrated by significantly inhibiting the production of LPS-stimulated pro-inflammatory cytokines such as IL-12, IL-6, and TNF-α in immune cells. In hair-related applications, it stimulates the proliferation of dermal papilla cells, crucial for hair growth, and inhibits 5α-reductase activity, an enzyme implicated in androgenetic alopecia. It also increases PGE2 production, contributes to enhanced skin hydration, and offers protection against UV-induced cellular damage. Furthermore, it exhibits anti-adipogenic activity by suppressing intracellular lipid accumulation and possesses inhibitory effects against Pityrosporum ovale, a common cause of dandruff.
