Science

Mechanism of Action

Dioscorea Batatas Extract exerts its effects through several pathways. As an antioxidant, it neutralizes free radicals and inhibits oxygen-favored reactions, thereby protecting skin from environmental aggressors. Its anti-inflammatory action is evidenced by its ability to reduce nitric oxide production, decrease reactive oxygen species, and suppress nuclear factor kappa B (NF-κB)-mediated inflammatory responses in cellular models. The extract also functions as an emollient, smoothing and softening the skin, and as an astringent to refine pore appearance. Furthermore, it supports skin hydration by enhancing moisture retention and strengthens the skin's natural protective barrier, making it more resilient to external factors. Preliminary research suggests potential anti-aging benefits through stimulation of collagen production and reduction of fine lines, while indications from a related species, Dioscorea villosa, point to a possible role in managing sebum overproduction.

Key findings

  1. 01 Demonstrated that concentrations of 0.5 and 1 mg/mL increased phosphorylation of AMP-activated protein kinase (AMPK) and Acetyl-CoA carboxylase (ACC) in C2C12 myotubes, suggesting a role in stimulating myoblast differentiation and mitochondrial biogenesis.
  2. 02 Showed reduced nitric oxide production and pro-inflammatory protein expression in LPS-stimulated RAW264.7 cells, decreased reactive oxygen species in hydrogen peroxide-stimulated HCT116 cells, and inhibited NF-κB-mediated inflammatory responses in macrophages.
