The instrument used to pierce you is not a minor detail. It determines how tissue is disrupted, what condition the healing channel starts in, and what jewellery options are available to you from the first moment. In New Zealand, clients often arrive having been pierced with a cartridge system — sometimes without knowing that was a different method with different implications. This article explains the distinction clearly.
The two methods explained
There are two fundamentally different mechanisms used in piercing:
The hollow needle is a single-use, sterile instrument with a sharp bevelled tip. When it passes through tissue, it removes a small core — creating a clean channel with defined walls. The needle is disposed of immediately after use. The jewellery is then inserted through that clean channel.
The cartridge system (or piercing gun) operates on pressure. A spring-loaded mechanism drives blunt jewellery directly through tissue by force. No tissue is removed. Instead, the tissue is compressed and displaced — pushed aside rather than cut cleanly. The cartridge holds the jewellery pre-loaded; what goes through the tissue is the finished piece, not a separate instrument.
These two mechanisms produce different results in tissue from the first moment of the procedure. That difference shapes everything that follows.
Why needle piercing is the professional standard
Professional piercing organisations globally — including the Australasian Union of Professional Piercers (AUPP), to which Platinum Point's piercers belong — specify needle use as a standard requirement. The reasons are not arbitrary:
- Clean tissue removal creates a channel with a predictable geometry. The healing tissue grows inward from defined walls. This is a more controlled start than compressed, displaced tissue.
- Precise gauge control — the needle diameter is exact and consistent. The piercer knows precisely what size channel they're creating, which informs jewellery selection directly.
- Minimal trauma — a sharp instrument moving cleanly through tissue causes less cellular disruption than blunt force applied across a broader area.
- Single-use disposal — every needle is opened from sealed sterile packaging in front of the client and disposed of immediately after use. There is no reuse, no resterilisation of the instrument itself, no cross-contamination pathway.
Thomas Manning, head piercer at Platinum Point, has a background as a Clinical Trials Aseptic Pharmacy Technician. That clinical background informs the standard applied to every needle technique at the studio — sterile field management, instrument handling, and procedural sequence are treated with the same rigour applied in pharmaceutical and clinical settings.
How cartridge systems work — and what they do differently
The cartridge or gun mechanism forces jewellery through tissue by spring-loaded or mechanical pressure. Because the tip of the jewellery is blunt — it's a finished piece, not a sharp instrument — the tissue doesn't part cleanly. It compresses under the advancing piece and then tears or splits as the force exceeds the tissue's resistance.
This tissue displacement is the source of greater initial trauma. The result is more cellular disruption at the piercing site, more initial inflammation, and a healing channel that begins in a less controlled state than a needle-pierced channel.
A secondary consequence: cartridge systems limit jewellery options to whatever is pre-loaded in the cartridge. The studio's own jewellery standards are not relevant — the jewellery is determined by the cartridge system, purchased from the cartridge supplier. The client has no ability to select jewellery grade, material, or style beyond what the system offers.
Healing implications
Greater initial tissue trauma translates directly into healing behaviour. What this means in practice:
- Increased initial swelling — the inflammatory response is proportional to the degree of tissue disruption. More disruption means more swelling in the first days and weeks.
- Greater healing variability — a clean needle channel gives the healing process a more predictable start. A compressed, displaced channel introduces more variability in how the fistula forms.
- More sensitivity to aftercare errors — tissue that starts healing in a less controlled state has less tolerance for additional irritants: touching, product exposure, pressure from sleep.
This is why lobe piercings performed with guns frequently take longer and behave more reactively than the same lobe position pierced with a needle by a professional. The anatomy is identical. The method differs. The outcomes reflect that difference.
Can cartridge piercings heal safely?
The honest answer: they can, particularly in lobe tissue. The lobe is vascular, forgiving, and relatively tolerant of imperfect starts. Many adults have lobe piercings done with guns in childhood that healed without lasting problems.
The evidence consistently favours needles for outcomes. The gap between methods is most significant in cartilage.
Cartilage tissue is avascular — it has minimal direct blood supply. This means it heals slowly and responds poorly to insults. Blunt-force piercing in avascular tissue causes a degree of tissue disruption that the tissue is not well equipped to resolve quickly. The risk of irritation, prolonged healing, and complications is substantially elevated. For this reason, cartilage should never be pierced with a gun or cartridge system. This is not a matter of preference — it is a clinical position supported by consistent evidence from professional piercing organisations and medical literature.
What jewellery comes with each method
With a needle piercing, the piercer selects and inserts appropriate jewellery after the channel is created. At Platinum Point, starter jewellery is ASTM F136 implant-grade titanium — a material standard with a clear specification, verified by the manufacturer. The jewellery choice is the studio's decision, informed by the client's anatomy and preferences.
With a cartridge system, the jewellery is pre-loaded. The material is whatever the cartridge supplier uses — typically described as "surgical steel" or "hypoallergenic", terms that are broadly undefined and unverified. The client has no ability to choose the material, gauge, or jewellery design. The cartridge system determines all of these by its own specification, which may or may not be disclosed clearly.
This matters because starter jewellery that doesn't meet implant-grade standards is a common source of healing problems — not the piercing technique itself, but the material sitting in healing tissue for months.
What to look for when choosing a studio in NZ
When assessing any Auckland or New Zealand piercing studio, these are the indicators of professional standard:
- AUPP membership — the Australasian Union of Professional Piercers sets standards that require needle use, autoclave sterilisation, and implant-grade materials. Membership is a meaningful baseline indicator.
- Single-use needles visible in sealed packaging — ask to see the needle before it's used. A reputable studio opens it in front of you from manufacturer-sealed packaging.
- Autoclave sterilisation — instruments in contact with the client (clamps, receiving tubes) are autoclaved between uses. Ask about this directly.
- Implant-grade jewellery declaration — ASTM F136 titanium, solid 14k/18k gold, or 950 platinum. The standard should be stated, not implied.
Frequently asked questions
Is a piercing gun the same as a cartridge system?
Largely yes. Both traditional spring-loaded piercing guns and modern cartridge systems operate on the same principle: blunt force drives jewellery through tissue by pressure rather than cutting. The cartridge format is a more modern iteration of the gun mechanism. Neither removes tissue cleanly the way a hollow needle does; both displace it by force.
Can cartridge piercings go wrong more easily?
There is more variability in healing outcomes with cartridge piercings, particularly in cartilage. In lobe tissue — vascular and forgiving — a cartridge piercing can heal well. In cartilage, the blunt force of a gun or cartridge system causes significantly greater tissue trauma in avascular tissue, which heals slowly and reacts poorly to that kind of disruption. Cartilage should never be pierced with a gun or cartridge system.
Does needle piercing hurt more than cartridge piercing?
Most clients find needle piercing less uncomfortable, not more. A sharp hollow needle creates a clean, brief cutting sensation. A cartridge system drives blunt jewellery through tissue by pressure — the sensation is more forceful and sustained. The common assumption that needles hurt more is not supported by typical client experience.
