DermFix™ — clinic-channel EV essences and repair formats
DermFix™ is TONGNIAN's professional-channel line: point-care essences and repair formats for aesthetics and dermatology practices. The line shares the fully enclosed 0.5–5 L micro-batch platform and the TONGNIAN characterization baseline; every batch ships with a COA, and clinic programs include protocol cards practices can adopt as-is.
Who this line serves
- post-procedure programs (all ages) — aftercare formats used within clinic-guided recovery periods.
- recurring breakouts (18–30) — point-care essences for targeted application within professional protocols.
- compromised barrier (18–25) — intensive formats for practices managing reactive, stressed-feeling skin.
- Aesthetics chains & dermatology clinics — white-label professional backbar and retail-aftercare programs.
