The procurement landscape for microneedling cartridges has shifted noticeably over the past 18 months.
Derma pens and electric microneedling devices differ in their needle motion mechanism. Derma pens use a reciprocating linear motion where needles move up and down vertically. OEM partners including tbphp test each device type against specific needle exposure tolerances that affect treatment consistency.
