Valuable CAS 223747-95-3 / SKIN CONDITIONING

A powerhouse botanical derived from Japanese Mugwort, this extract serves as a cornerstone for reparative skincare by bridging traditional wisdom with modern dermatological science. It is engineered to fortify the skin's structural integrity while providing a profound calming effect on reactive complexions.

soothing antioxidant barrier-repairing antimicrobial skin-conditioning

Science

It functions as a biological architect for the skin barrier by activating the AHR/OVOL1 pathway, which directly increases the production of essential structural proteins like filaggrin and loricrin. Simultaneously, it triggers the NRF2 antioxidant pathway to neutralize oxidative stress and suppresses NF-κB activity to mitigate inflammatory responses.

Key findings

  1. 01 Demonstrated significant upregulation of filaggrin and loricrin at 0.03% concentration via the AHR/OVOL1 axis (Hirano et al., 2017).
  2. 02 Observed antimicrobial and anti-biofilm activity against MRSA at concentrations between 0.1% and 0.8% (Choi et al., 2015).

While many brands list this extract for marketing appeal, its biological activity begins at a remarkably low threshold of 0.03%. Formulas containing less than this amount are likely 'dusted' and will fail to trigger the protein upregulation required for barrier repair.
