The 42-pin needle provides broader surface coverage for full-face collagen induction or large body areas. Accepts direct ampoule attachment for simultaneous needle-channel delivery.
Designed for use with the AUTO MTS PEN in professional MTS protocols delivered by trained operators within established cabin procedures.
20 pieces per box; 42-pin needle cartridges, depth range 0-2.0 mm, 0.3G gauge.
Attach the cartridge securely to the AUTO MTS PEN and confirm the depth stop is set per the planned protocol (0.25–0.5 mm for mesotherapy delivery, 0.5–1.0 mm for collagen induction, up to 2.0 mm for scar treatment). Apply the active serum to the skin surface. Use the 42-pin cartridge for broad-coverage passes. Complete 2–4 passes per zone in a cross-hatch pattern. Discard the cartridge in a sharps container after each client session; cartridges are non-resterilisable.
