About the RejuvaSILK™ line
RejuvaSILK™ is TONGNIAN's skincare-track material line: lyophilized EV powder, patch masks, and rose-derived plant EVs — one characterization baseline across mass-retail skincare programs. The RejuvaSILK™ line fact-sheet lists every dosage form, the characterization baseline and the filing status in one place; this page documents a single program from that line.
