RejuvaSILK™: three skincare dosage forms on one documented EV baseline
RejuvaSILK™ is TONGNIAN's skincare-track EV line: lyophilized powder, patch masks, and rose-derived plant stock solution for anti-aging, sensitive-skin, and post-procedure retail. Every ingredient batch runs on the fully enclosed 0.5–5 L micro-batch line — seed line, scale-up, and purification in one sealed system, checked against one characterization baseline. Every shipment includes a COA and characterization summary, with additional test panels available to match channel requirements.
Who this line serves
- post-procedure retail (all ages) — aftercare retail that extends clinic treatments onto the home shelf.
- Gen-Z sensitive skin (18–25) — barrier-companion formats for reactive, stressed-feeling skin.
- light anti-aging (30–40) — first anti-aging lines built on documented ingredients rather than adjectives.
- recurring breakouts (18–30) — soothing companion formats within breakout-care routines.
- premium silver anti-aging (55–70) — premium tiers for the fastest-growing beauty demographic.
