Precision Microcrystal™ — acupoint EV suspension for clinic and retail formats
Precision Microcrystal™ is TONGNIAN's delivery line: an acupoint microcrystal suspension with matched carriers and device formats for guided-placement programs. The line extends TONGNIAN's delivery-platform know-how (NanoCrystal™-family transdermal work) into guided placement; every batch ships with a COA and characterization summary on the shared platform baseline.
