When to Replace an Aesthetic Machine

Updated 6 November 2026

Replace an aesthetic machine when the cost of keeping it, meaning repairs, downtime and lost bookings, is running ahead of what a newer unit would cost you per treatment, or when it can no longer deliver results patients will pay for. Age alone is a weak signal. A well-serviced ten-year-old platform can outearn a neglected three-year-old one.

Key takeaways

  • Replace an aesthetic machine when repairs, downtime and lost bookings cost more than a newer unit would, not simply because it is old.
  • Machines wear in specific parts: our machine pages name lamps on the M22 and Stellar M22, the handpiece on the Soprano and the tube on the UltraPulse as the lifed parts.
  • On our hypothetical 24-month example, repairing costs €10,000 against €20,500 to replace, so repair wins unless the repair quote or downtime is much larger or the new unit adds revenue.
  • Sell while the machine still works: a serviced, documented unit sits nearer the top of its used range, which for the GentleMax Pro is €25,000 to €50,000 on our machine page figures.
  • The 8-year tax write-off in Ireland is an accounting convention, not a lifespan, so do not use it to decide when a machine is finished.

Why "how old is it?" is the wrong first question

Aesthetic machines do not wear out on a calendar. They wear out in specific parts: lamps, handpieces, tubes, cartridges and applicators. Our machine page figures make this concrete. The Lumenis M22 and Stellar M22 carry lamp life as the recurring cost, the Alma Soprano's handpiece is the lifed part, and the UltraPulse CO2 laser's tube is the lifed part. A machine is "due" when its lifed parts are due and the quote to refresh them looks poor against the alternative.

So the useful questions are about condition, support and demand, not birth year.

Five signs it is time

  1. Downtime is costing you bookings. Keep a simple log of every day the machine was unavailable, and the treatments you rescheduled or cancelled. Two or three losses a year is normal. A pattern of faults in the same subsystem is not.
  2. Parts or service are getting harder to source. Our Ultraformer III page tells buyers to check Irish cartridge supply, and the CoolSculpting page notes that the original unit has been superseded by CoolSculpting Elite. When the maker moves on, the original platform's support tends to thin out. Ask your engineer, in writing, how long they expect to support your model.
  3. Results or consistency have slipped. Patients notice before you do. If the same protocol gives weaker or patchier outcomes than it used to, have the output tested before blaming technique.
  4. The treatment has been overtaken. Sometimes a newer device does more with one chassis. The Stellar M22 page describes one platform replacing several single-purpose devices, which is a reason clinics upgrade from a single-purpose unit.
  5. Demand has moved. If enquiries are now for a different treatment, your best machine may be the wrong machine. Replacing is then about repositioning, not condition.

A repair-versus-replace test you can run in ten minutes

Take three numbers and compare them over the next 24 months. The figures below are hypothetical, for illustration only, so swap in your own quotes.

LineKeep and repairReplace
Repair or service quotes€6,000€0 (under warranty)
Revenue lost to downtime€4,000€500
Net cost of capital (price minus sale of old unit)€0€20,000
Total over 24 months€10,000€20,500

On those hypothetical numbers, repairing wins. It flips only if the repair quote is much larger, downtime is chronic, or the new unit adds revenue the old one cannot, such as a new treatment or a faster protocol. Add that extra revenue to the replace column honestly, and be sceptical of the supplier's utilisation claims.

Time the sale, not just the purchase

A machine loses value fastest when it stops working. A unit that is serviced, complete and demonstrably running sits in the upper part of its used range, while one with a fault is priced for repair risk. Our figures show how wide those ranges are: the GentleMax Pro runs from about €25,000 to €50,000 used, and the HydraFacial MD Elite from about €5,500 to €22,500. Much of that spread is condition and documentation.

That points to a sequence many clinics miss:

  1. Decide to replace while the old machine still works.
  2. Get a service report and photograph the pulse or shot counts.
  3. List the old machine and agree the new purchase in parallel, so the sale funds the purchase.
  4. Keep the old unit running until the replacement is installed, so you are never without a service line.

You can list your machine free, with no commission, and our sell page covers how it works. If you would rather go through a dealer, read selling privately versus to a dealer and trade-in or sell your old machine first.

Should the replacement be new or used?

If your old machine still has a healthy used market, a used replacement of the same family can be the lowest-risk move: your staff already know the protocol and your patients already know the treatment. For laser hair removal, compare the options on our laser hair removal category and browse what is currently listed in the classifieds. Our new versus used framework sets out the trade-offs.

What not to do

  • Do not replace because a rep says the new model is "a generation ahead" without asking what changes for your patients.
  • Do not leave a failing machine until it dies. Sell while it works.
  • Do not forget the consumable lock-in on the new platform. Our Syndeo page notes a consumable contract is required, and Morpheus8 tips are only available through the official channel.
  • Do not skip the question of training. Several BTL platforms require manufacturer certification.

Check with your insurer and the HPRA if a change of device affects your cover or your obligations. Prices vary by unit, so get written quotes and inspect any machine before you buy.

Frequently asked questions

How long does an aesthetic machine last?

There is no single figure, because it depends on the technology and on how well it is serviced. Lifed parts such as lamps, handpieces and tubes usually decide it, so ask your engineer for the expected life of yours.

Is it better to repair or replace a laser?

Compare the repair quote plus lost bookings against the net cost of a replacement over the next two years. If the repair is a one-off and the machine is otherwise sound, repairing usually wins.

When is the best time to sell an old aesthetic machine?

While it still works, with a recent service report and photographed counts. A running, documented unit sells nearer the top of its used range.

Can I sell a machine that needs repair?

Yes, but disclose the fault clearly and expect buyers to price in the repair risk. A written quote for the repair helps both sides agree a fair price.

How is an aesthetic machine written off for tax in Ireland?

Revenue's note for guidance describes a straight-line wear and tear allowance of 12.5% a year over 8 years for plant and machinery bought on or after 4 December 2002. That is a tax rule, not an estimate of how long the machine lasts.

Is there a tax charge when I sell my old machine?

Possibly. The Revenue note says a balancing charge arises when sale proceeds exceed unallowed cost, capped at the allowances given, and a balancing allowance arises when proceeds are lower. Ask your accountant how it applies to you.

How do I know if my laser's output has drifted?

Ask your service engineer for a written output test and compare it with the manufacturer's specification. We do not give a threshold because it differs by device.
