You’ve seen them everywhere. In the back of a mall kiosk, on a shelf at the local pharmacy, or even in a "value pack" online for twelve bucks. The plastic, spring-loaded tool that promises a quick snap and a shiny new stud in your ear. But if you’re asking how do you use a piercing gun, you’re likely standing at a crossroads between convenience and a potentially nasty infection.
It looks easy. Honestly, it’s designed to be foolproof. You line up the point, squeeze the handle, and—presto—you're accessorized. But there is a massive gap between "making a hole" and "performing a safe body modification."
Most professional piercers, like those certified by the Association of Professional Piercers (APP), will tell you that these devices are a nightmare. They don't just "pierce" the skin; they use blunt force trauma to jam a dull stud through your tissue. Think of it like a hole punch vs. a needle. One slices cleanly; the other just rips.
But if you are determined to understand the process or find yourself in a situation where this is the only option being offered, you need to know exactly how they function—and why the "traditional" way might be a bad idea for your body.
The mechanics of the spring-loaded stud
Most people think the gun "fires" a needle. It doesn't. When you look at how do you use a piercing gun, the first thing you notice is that the earring itself is the needle.
The device holds a pre-sterilized starter stud in a plastic cradle. These studs are sharpened to a point, but they are still significantly blunter than a surgical hollow-point needle. When the trigger is pulled, a high-tension spring releases a plunger. This plunger slams the back of the earring through your earlobe and into the butterfly backing held on the other side of the device.
It happens fast. Usually under a second. This speed is what makes it popular for kids. They don't have time to get nervous because by the time they hear the "clack," the job is done.
However, that speed comes at a cost. The force required to push a blunt object through skin often causes micro-tears in the surrounding tissue. This is why "gun piercings" often throb for days, whereas a professional needle piercing usually feels like a dull ache for about twenty minutes.
Preparing the site (The step most people skip)
If you’re watching someone use a piercing gun, or god forbid, doing it yourself, hygiene is the only thing standing between you and a staph infection.
The area has to be scrubbed. Not just a quick wipe with an alcohol pad, but a thorough cleaning with a surgical-grade skin prep like Betadine or a high-concentration isopropyl alcohol. Most mall shops just give a quick swipe. That’s not enough.
You also have to mark the spot. A surgical skin marker is best. Don't use a Sharpie. Sharpies aren't sterile and can actually tattoo the ink into the fresh wound if the earring passes through it.
The alignment check
When you're ready to go, the gun is positioned so the lobe is sandwiched between the earring carriage and the backplate.
- Height: Is it centered in the lobe? Too low and it might tear through over time.
- Angle: Is the gun perfectly perpendicular to the skin? If it’s tilted, the exit hole will be lower than the entry hole, making the earring sit crooked forever.
- Pressure: The operator should apply steady pressure to the trigger until the "stop" is felt before the final click.
Once it's lined up, the operator gives a firm, quick squeeze. The spring does the work.
Why "one size fits all" is a lie
The biggest issue with the mechanics of the piercing gun is the earring length. Every human ear is a different thickness.
When you use a gun, the backing is usually snapped into a pre-set notch on the earring post. This doesn't account for the inevitable swelling. When skin gets a hole punched in it, it inflames. It gets thick. If the earring is too short—which "gun" studs almost always are—the skin can actually grow over the earring.
I’ve seen this happen. It’s called embedding. It usually requires a doctor to numbing the ear and cutting the jewelry out with a scalpel. It’s not fun.
The sterilization myth
Here is the dirty secret about piercing guns: they are almost impossible to truly sterilize.

True sterilization requires an autoclave. An autoclave uses high-pressure steam to kill every living thing on a tool. Most piercing guns are made of plastic. If you put a plastic gun in an autoclave, you get a melted puddle of blue or white goo.
Instead, shops "wipe them down." But when that spring snaps, it creates a microscopic mist of blood and tissue. This is called aerosolization. That "mist" can get into the internal springs and crevices of the gun. The next person who gets their ears pierced is now sharing biological material with everyone who came before them.
Newer "disposable" systems, like the Inverness or Studex 75, try to solve this by having the entire "gun" part be a one-time-use cartridge. This is much safer, but the blunt-force trauma issue still remains.
What happens after the "click"
So, the hole is there. Now what?
Most people are told to "turn the earrings" twice a day. Don't do this. This is old-school advice that has been debunked by medical professionals. When your body tries to heal, it forms a "tunnelling" of new skin cells called a fistula. If you twist the jewelry, you are essentially ripping those new cells away and dragging bacteria into the open wound. It’s like picking a scab from the inside out.
Instead of twisting, you should be using a sterile saline spray (like NeilMed) twice a day. Leave it alone. Don't touch it with dirty hands. Don't put Claire’s "Ear Care Solution" (which is often just diluted bleach or harsh chemicals) on it.
The cartilage danger zone
If you are wondering how do you use a piercing gun for your nose or the top of your ear—stop. Just don't.
Cartilage is not like a lobe. It doesn't have the same blood flow. If you use a piercing gun on cartilage, the blunt force can actually shatter the cartilage plate. This leads to "cauliflower ear" or permanent scarring that looks like a lumpy mess.
Professional piercers use a hollow needle for cartilage because it removes a tiny "sliver" of tissue to make room for the jewelry. A gun just pushes the cartilage aside, causing it to crack under the pressure. It's a recipe for a six-month-long infection that smells like old cheese.
Red flags to watch for
If you are at a place that uses a gun, and you see any of the following, walk away.
- They don't wear gloves. This should be obvious, but you'd be surprised.
- They don't mark your ear. "Eyeing it" is a great way to end up with lopsided holes.
- The gun looks dirty. If there is visible gunk on the tool, run.
- They say it's fine for your nose. It isn't. Ever.
- They tell you to clean it with peroxide or alcohol. These are too harsh for a fresh piercing and actually kill the cells trying to heal the hole.
The real cost of a "cheap" piercing
A mall piercing might cost $30 (or "free" with the purchase of jewelry). A professional shop might charge $60 plus the cost of high-quality titanium.
Is the $30 savings worth it?
Consider the jewelry material. Piercing guns almost always use "surgical steel," which is a fancy way of saying it has a lot of nickel in it. About 10% of the population has a nickel allergy. If you're one of them, your ear will turn green, itchy, and weep fluid within 48 hours.
Professional shops use implant-grade titanium (ASTM F-136). It's the same stuff they use for hip replacements. Your body doesn't react to it. It heals faster. It feels better.
Actionable steps for a successful piercing
If you've already used a piercing gun or are about to, here is how you minimize the damage:
- Swap the "cleaning solution": Toss the bottle they gave you. Go to the pharmacy and buy "0.9% Sterile Saline Wound Wash." It’s just salt and water. It’s what your body wants.
- Stop the twisting: Seriously. Quit it. Let the skin form around the post naturally.
- Check the backing: If the butterfly back is pushed too tight against your ear, loosen it. Your lobe needs room to breathe. If you can’t see the post between the backing and your skin, it’s too tight.
- Sleep on your back: Putting pressure on a fresh "gun" piercing will cause it to migrate or heal at a weird angle. If you must sleep on your side, use a travel "donut" pillow and put your ear in the hole.
- Wait to change it: They tell you 6 weeks. Wait 12. Lobe piercings heal from the outside in, so it might look healed when the inside is still a raw mess.
Honestly, the best way to "use" a piercing gun is to not use one at all. Go see a professional who uses a needle. It hurts less, heals faster, and you won't be sharing a spring-loaded device with the 400 people who came before you. But if you're already in the chair, keep that saline handy and keep your hands off the jewelry. Your ears will thank you.
