How to Sterilize and Store Plasma Pen Needles Between Sessions
Plasma pen therapy — formally known as plasma fibroblast treatment (a non-surgical skin-tightening procedure that uses an ionized gas arc to sublimate superficial skin tissue and stimulate dermal collagen remodeling) — delivers results precisely because its needles make controlled contact with living skin. That proximity to open tissue is also what makes needle hygiene the single most consequential variable in both safety and outcome. This guide translates government infection-control regulations and peer-reviewed clinical evidence into a clear, session-by-session protocol you can follow at home or in a salon setting. Before you begin any treatment, review the SKINDELÚX Plasma Pen Instruction Guide to ensure your device is set up correctly from the outset.
Why does needle sterilization matter so much in plasma pen therapy?
Plasma pen needles matter so much because every treatment session creates microscopic breaches in the skin barrier — and any pathogen on the needle tip can pass directly into subcutaneous tissue before the immune system has a chance to respond.
Procedures that involve skin penetration carry a higher risk of spreading disease. This is not theoretical: unsafe injection and needling practices have been associated with disease transmission and are explicitly prohibited by the CDC. In a plasma pen context the needle does not hollow-bore inject fluid, but it does ablate the epidermal surface and can carry biological material — sebum, blood, skin debris — from one treatment zone to another, or from one session to the next if the needle is not handled correctly.
Sterilization is a process that kills micro-organisms including bacteria (and their spores), fungi and viruses. Disinfection, by contrast, only reduces microbial load to a safe level but does not eliminate spore-forming bacteria. For any instrument that breaches the skin, sterilization — not mere disinfection — is the target standard. For background on the skin conditions and contraindications that make this especially important, consult the SKINDELÚX Plasma Pen Safety Notice.
Can plasma pen needles be reused between sessions?
The authoritative answer is no for needles, and conditional yes for the device body — a distinction governed by whether a component contacts broken skin directly.
Instruments that penetrate the skin and cannot be effectively cleaned and sterilised must be single-use; needles (including tattoo needles) and razors must not be reused. If needles are used in skin penetration procedures, they must be sterile, single-use and disposed of into an appropriate sharps container directly after use. These requirements, issued by NSW Health under the Public Health Regulation 2022, align with CDC guidance that needles, cannulae and syringes are sterile, single-use items that should not be reused for another patient nor to access a medication or solution that might be used for a subsequent patient.
The practical implication for plasma pen users is straightforward: each session demands a factory-fresh, sealed needle. If you are running low on consumables, SKINDELÚX Extra Needles for Plasma Pen (102pcs Pro Pack) is designed to keep a full professional supply on hand without compromising on single-use discipline. To understand which needle tip type (fine, coarse, curved, or straight) is appropriate for each skin concern before you open a new needle, see the SKINDELÚX Plasma Pen Needle Guide.
How should you prepare the workspace and your hands before handling needles?
Workspace and hand preparation form the first line of defense, because a sterile needle contaminated by an unsanitary surface or ungloved fingers is no longer sterile.
Wash or disinfect hands before preparing injection material and giving injections. The WHO further specifies using a 60–70% alcohol-based solution for skin and surface disinfection. Sterile parts of equipment that will penetrate the skin must not be touched with bare hands; if sterile equipment needs to be touched, a pre-packed sterile alcohol swab, a sterile dry swab, or sterile single-use gloves must be used.
Lay out all consumables on a clean, freshly disinfected tray before opening any packaging. Keep the zone separate from "dirty" areas (used gloves, paper towels, spent needles) to prevent cross-contamination. This clean/dirty zoning is a universal principle in skin-penetration infection control.
What is the correct step-by-step protocol for opening and fitting a new plasma pen needle?
Opening a needle correctly preserves its factory sterility right up to the moment of contact with skin — and that is exactly when sterility needs to be intact.
Follow this sequence before every session:
- Inspect the sealed packaging. Check the foil or blister pack for any tears, pinholes, or discoloration. Follow the manufacturer's instructions for use (IFU) and storage instructions; immediately prior to use, remove the needle from sterile packaging. Any damaged packaging renders the needle non-sterile; discard and use a new one.
- Verify the sterility indicator. Quality needle packs include a colour-change indicator on the autoclave pouch or foil. Confirm it has shifted to the validated "sterile" state. Ensure sterile packaged equipment is labelled with the manufacturer's statement that it is sterile.
- Open the pack without touching the needle tip. Always grip the needle by the plastic base and never touch the metal tubing. Peel the foil back and allow the needle to slide or drop directly onto a sterile field or into the pen mount — no intermediate resting on the tray surface.
- Fit to the device using gloved hands only. Even if the needle base is considered a "non-critical" surface, bare skin can transfer microorganisms. Single-use, non-sterile nitrile gloves are the minimum; sterile gloves are preferred in clinical settings.
- Swab the client's skin with 70% isopropyl alcohol before treatment. According to the World Health Organization (WHO), it is a common practice to clean the injection site with a saturated 60–70% alcohol swab for 30 seconds, because needles can penetrate the skin barrier and increase the risk of infection; alcohol swabs effectively reduce the number of bacteria on the skin by 47–91%.
What should you do with the needle immediately after a session ends?
Post-session needle management is non-negotiable: a used plasma pen needle must be treated as clinical sharps waste from the instant the tip is withdrawn from the skin.
A person who carries out a skin penetration procedure must not use a needle that has previously been used in a skin penetration procedure; a person who uses a needle in a skin penetration procedure must dispose of the needle in a sharps container. Dispose of needles in appropriate sharps containers. Never recap with two hands (a leading cause of needlestick injury) — use a one-handed scoop technique or a needle-guard device if available.
Sharps containers must be puncture-resistant, leak-proof, and labeled. In hospitals and clinics the healthcare industry uses special containers dedicated for the disposal of needles and other invasive devices; sharps containers with used needles are then disposed of by industrial waste collectors and are usually either burned, disintegrated or buried, depending upon local healthcare regulations. For home users, many pharmacies accept sealed sharps containers for safe disposal — check your local authority guidelines.
How should unused, factory-sealed needles be stored to preserve their sterility?
Correct storage of unused needles protects the factory sterility guarantee and ensures every new session starts from a verified clean baseline.
Apply this storage checklist:
- Temperature and humidity: Store sealed packs at room temperature (15–25 °C / 59–77 °F) in a dry environment. Heat, humidity, and UV exposure can compromise the integrity of foil or blister packaging and degrade any sterility barrier inside.
- Original packaging only: Pen needles are typically packaged individually and disposed loose in a container; each needle is sealed with a label laminated thereto to provide a sterility barrier. Do not transfer individual needles to a secondary container such as a zip-lock bag or pill organizer; the original factory seal is the sterility guarantee.
- Separation from contaminants: Keep sealed needle packs in a designated, closed cabinet — away from chemical vapors, aerosols, cleaning agents, and humid areas like sinks or autoclaves in active use. Cross-contamination of packaging (not just the needle itself) is a recognized but underappreciated hygiene failure point.
- FIFO rotation: Use a First-In, First-Out inventory system. Place newly received packs at the back of the storage area and draw from the front. Sterility expiry dates exist on most medical-grade packs; check and honor them.
- Visible pre-use check: Before each session, hold each pack up to light and confirm no micro-tears, moisture ingress, or indicator failure. If in any doubt, discard.
How should the plasma pen device body be cleaned between sessions?
The device body — the handpiece — does not penetrate skin, but it can accumulate microbial load from the operator's hands and the treatment environment, so cleaning between sessions is still essential.
All equipment needs to be in good working order, be cleaned and dried after use and be kept in a clean and dry condition. For the handpiece specifically: power off the device, detach and dispose of the used needle per the protocol above, then wipe all external surfaces with a 70% isopropyl alcohol wipe, working from the tip end toward the grip. Allow to air-dry fully before storing or recapping. Do not submerge the handpiece in liquid or use spray disinfectants directly onto vents or the charging port — moisture ingress damages electronics and can create galvanic corrosion on metal contacts.
Store the cleaned device in its original case or a clean, closed pouch. All equipment needs to be in good working order, cleaned and dried after use, and kept in a clean and dry condition.

What is the professional standard for salons and aesthetic practitioners?
Salons have elevated obligations because they treat multiple clients sequentially, and a single hygiene lapse can create a chain of cross-contamination.
The Public Health Regulation 2022 requires all reusable instruments that penetrate a person's skin to be sterilised in line with AS 5369:2023 and be kept in a sterile condition until used in a skin penetration procedure. Sterilisation must be carried out using a steam-under-pressure bench top autoclave in line with AS 5369:2023 Reprocessing of reusable medical devices and other devices in health and non-health related facilities. Note that ultrasonic cleaners clean but do not sterilise instruments — a common confusion in aesthetic practice settings.
Salons should maintain a written sterilization log recording each autoclave cycle date, temperature, pressure, and load contents. NSW Health states that the autoclave used for steam sterilisation of reusable skin penetration instruments should be registered by the Therapeutic Goods Administration (TGA). For client-facing documentation, the SKINDELÚX free Plasma Pen Consultation & Consent Form template includes sections for recording the sterile status of consumables used in each session, creating a transparent paper trail.
Your Next Step
Safe needle hygiene is not an optional extra — it is the foundation on which every plasma pen result is built. Starting each session with a verified sterile, single-use needle and disposing of it correctly afterward is the most evidence-based thing you can do to protect skin and maximize the longevity of your results. Keep your supply consistent and clinical with the SKINDELÚX Extra Needles for Plasma Pen (102pcs Pro Pack) — 102 individually sealed, single-use needles engineered to work with the SKINDELÚX (Skin Delux) device so you never have to compromise on sterility between sessions.
Frequently Asked Questions
- Can I sterilize a used plasma pen needle with alcohol and reuse it?
- No. Alcohol wipes and soaks are classified as disinfectants, not sterilants — they reduce microbial load but cannot guarantee elimination of all bacterial spores or viruses. More importantly, used plasma pen needles are classified as single-use skin-penetration instruments under public health regulations in most jurisdictions. Even if you could achieve chemical sterilization, the mechanical tip of a used needle may be microscopically barbed, which damages tissue on reuse and defeats any sterilization effort. Always use a new, factory-sealed needle for every session.
- What type of sharps container should home users of a plasma pen use?
- Home users should use an approved puncture-resistant, leak-proof sharps disposal container — the same kind used for insulin pen needles. These are sold in pharmacies without prescription in most countries. Never dispose of used plasma pen needles in household recycling or general waste bins, as they pose needlestick injury risks. When the container is roughly three-quarters full, seal it and take it to a pharmacy, hospital waste point, or designated household hazardous waste facility per your local authority's guidance.
- How long does a factory-sealed plasma pen needle remain sterile in storage?
- Factory sterility is maintained as long as the original sealed packaging remains intact and is stored correctly — typically at room temperature (15–25 °C), away from moisture, UV light, and chemical vapors. Medical-grade packaging carries a printed sterility expiry date; check this date before every use. If packaging shows any sign of damage — a pinhole, tear, discoloration, or failed sterility indicator — discard the needle regardless of the expiry date.
- Is it safe to use a plasma pen needle on more than one skin area in the same session?
- Yes, within a single session on the same client, moving the same needle across different treatment zones (e.g., from the eye area to the jaw line) is acceptable provided the needle has not been contaminated by contact with an infected area, the skin has been properly prepared, and you are following your device's recommended technique. However, once the session ends and the device is set down, the needle must be treated as used and discarded. Never store a partially used needle for a follow-up session — even on the same client.
- Do I need to sterilize the plasma pen handpiece as well as the needle?
- Yes, but the method differs. The handpiece (device body) does not penetrate skin, so it falls into a lower risk category than the needle itself. Regular surface disinfection with a 70% isopropyl alcohol wipe after every session is the standard approach. The handpiece should not be autoclaved, as steam and high pressure will damage its electronics. Focus full sterilization protocol on any component that contacts broken skin — which for plasma pen treatment means the needle tip exclusively, and those must always be single-use.
- What does "AS 5369:2023" mean, and does it apply outside Australia?
- AS 5369:2023 is the Australian/New Zealand Standard for the reprocessing of reusable medical devices, referenced by regulators such as NSW Health as the benchmark for skin-penetration sterilization in beauty and aesthetic businesses. While this standard is jurisdiction-specific, its principles — thorough mechanical cleaning before sterilization, validated autoclave cycles, documented sterility assurance, and single-use classification for needles — mirror the frameworks applied by the CDC in the United States, the NHS in the United Kingdom, and the WHO globally. Wherever you practice, single-use needles for skin-penetration procedures represent the universal professional standard.
