How to Inspect a Used Aesthetic Machine: Checklist

Inspect a used aesthetic machine in four stages: paperwork before you travel, a cold power-up, a working test of every handpiece, then a check of consumables and support. Do it with an engineer if you can, allow at least an hour, and do not pay until every stage is passed or the shortfalls are priced into the deal.

What paperwork should you ask for before you travel?

Ask for these by email so you have them in writing. If the seller cannot supply them, the price should reflect that.

• Serial number and a photo of the serial plate
• Original invoice or proof of ownership
• Last service report and who carried it out
• Photos of the console showing usage counters
• A list of everything included
• Confirmation that no finance or lease is outstanding

Compare what you are told with the model's machine page. Our Lumenis M22 page lists lamp life per head and sapphire lightguide care as the running items, and our Stellar M22 page says lamp replacement is quoted per handpiece. Every platform has its own "lifed part", and a good seller will know which it is. Ask for maintenance logs showing cleaning, part replacements and calibrations (MissLJBeauty).

How do you do a cold power-up test?

Ask the seller not to switch it on before you arrive, because a cold start shows faults a warm machine hides.

1. Watch the start-up sequence and note any error or warning codes.
2. Check how long it takes to reach ready, and listen to the fans and pumps.
3. Confirm the screen responds across the whole surface.
4. Read the counters and check they match the photos you were sent.
5. Look for any software locks, expired licences or a prompt for a service key.

Photograph any fault, so you can negotiate with evidence.

What should you check physically?

How do you test every handpiece?

Test every handpiece, not just the one the seller shows you.

• Run each handpiece across the settings you would use in practice, from low to high.
• For IPL and laser systems, check output consistency. Have an engineer measure it with an energy meter, because Ophir notes IPL devices rely on internal monitoring and advises comparing real output with the displayed setting (Ophir). A visual check alone does not tell you the energy is correct.
• Check cooling on contact and on air systems, which affects patient comfort and safety. Candela's maintenance guide also lists regular visual inspection, clean components and a checked dust filter as routine care (Candela), so a clogged filter suggests neglect.
• For RF and microneedling systems, confirm each tip or applicator is recognised, and ask what happens when a disposable is not genuine.
• For HydraFacial-type units, watch for suction consistency, leaks and whether branded consumables are recognised, as our machine pages say tips and serums must come through the brand.
• For HIFU, check that cartridges register and count correctly, and ask where replacements come from in Ireland.

Run it for at least 30 minutes and test again, because overheating and intermittent faults appear after warm-up.

What consumables and support should you confirm?

A machine that works today but cannot be supported is a bad purchase.

• Who services this model in Ireland? Our pages list the support route per brand, such as Lumenis UK and Ireland engineers or the HydraFacial UK and Ireland distributor.
• What are the lifed parts, and what is the replacement cost? Ask for quotes from the manufacturer or distributor, not the seller.
• Is software upgradable, and does the machine need a licence key to operate?
• Are any applicators or handpieces beyond their life, and are the counters real?

Our page on the original CoolSculpting unit notes that warranty is rarely available, so the checklist matters most when there is no safety net.

How do you score a go or no-go decision?

Score each area 0 for a failure, 1 for a concern, 2 for fine and 3 for excellent. This is a simple way to organise your decision, not an industry standard.

1. Paperwork and ownership
2. Cold start and error log
3. Physical condition
4. Function test on every handpiece
5. Consumables and support in Ireland

Any 0 should stop the purchase until it is resolved in writing. Several 1s are a basis for negotiating, using documented quotes for the repair or replacement.

Who should come with you?

An engineer who knows the platform is worth their fee on a machine costing five figures. If you cannot arrange that, ask a clinician who has used the model daily, and ask the seller if you may film the test.

What about compliance and insurance?

Ask the seller for the CE documentation, check with the HPRA what applies, and tell your insurer before you buy, because they may want service records or training evidence.

What do you do after the inspection?

If the machine passes, put the agreed price, inclusions, fault disclosures and serial number on an invoice and pay by bank transfer. Read our guide to used machine scams in Ireland for the payment sequence, and our guide on what to ask about service history for the records that should back up what you saw.

Frequently asked questions

How long should an inspection of a used aesthetic machine take?

Allow at least an hour for a single handpiece system and longer for a multi-handpiece platform. Include a cold start and a second test after warm-up.

Should I bring an engineer to inspect a used machine?

If the machine costs five figures, yes. An engineer can measure output and read error logs, which a visual check cannot.

What are the biggest red flags during an inspection?

Persistent error codes, a seller who switches the machine on before you arrive, counters that do not match the photos and handpieces that are not recognised. Slow start-up, warning messages and inconsistent pulse output are also warning signs (MissLJBeauty).

What does a high pulse count mean on a used laser?

It means the laser has been heavily used, so compare the count with the manufacturer's recommendations for that model, since some parts wear out much sooner than others (MissLJBeauty). Ask the distributor what the lifed part is and its replacement cost.

How can I check the output of a used IPL or laser?

Use a proper energy or power meter and compare the reading with the displayed setting, rather than trusting the screen (Ophir). An engineer should do this, and Candela's guide also says output should be checked before and after use (Candela).

Can I buy a used machine without seeing it work?

Avoid it. One buying guide says never to buy a used medical laser without seeing it in action (MissLJBeauty). If you cannot travel, ask for a live video call showing a cold start, the serial plate and the counters.

Can I negotiate the price after finding faults?

Yes. Get a written quote for the repair, then agree a reduction or ask the seller to fix it before sale.

Prices vary by unit, so get written quotes and inspect any machine before you commit.
