Buying a used or low-cost laser device: what you need to look out for
A used laser device or a conspicuously cheap offer looks like the fast route to a laser of your own. Whether the price delivers what it promises only becomes clear from the shot count, service history, spare parts, software locks and documentation. This page explains what you need to look out for before buying and which costs follow afterwards.
You will also find out when buying used can make sense and how the calculation compares with a leased new device. The benchmark is SIACSKIN devices with their stated service lives, such as the DEWEON 4LD and the AlexDUAL UFO, with a 2-year manufacturer's warranty, training and service from the manufacturer.
What should I check when viewing a used laser machine?
Check five things on site: the shot count of the device and handpiece, the service history, the condition of the optics and cooling, the software access and the performance in continuous operation. Ask to see maintenance logs and repair invoices and compare the serial number on the rating plate with the paperwork. Look at the handpiece window: burn marks, cracks or cloudy areas indicate damage. Have the device demonstrated in treatment mode for at least 30 minutes, ideally on a test person, and watch out for error messages, temperature warnings and leaking hoses.
A look at a new device helps as a benchmark. With the DEWEON 4LD the service life of the handpiece is around 100 million shots, plus a 2-year manufacturer's warranty and the training. These are the points against which you measure every used offer.
How many shots can a used laser have, and can the shot counter be reset?
What matters is not the absolute figure but how much of the designed service life has already been used up. A handpiece with 15 million shots is almost new if it is built for 100 million, and three quarters used up if the source is designed for 20 million. So always ask for both values. On some devices the counter can be reset via the service menu, and a replaced handpiece has a different count from the base unit. Therefore compare the counter with the maintenance logs and the previous owner's workload.
For reference, the figures from SIACSKIN: the handpiece of the DEWEON 4LD is designed for around 100 million shots, the crystal of the AlexDUAL UFO for 100 million shots, and the PICOLO S for 5 million shots.
How do I check whether a cheap laser machine really delivers the stated power?
Only a measurement shows the true output: an energy meter at the handpiece measures what actually arrives per pulse. Wattage figures on the housing or in the brochure often describe the power consumption or a calculated peak power. Have the energy measured in front of you at a fixed spot size and pulse duration, once cold and again after 30 minutes of operation. If the value drops markedly, the cooling is inadequate. A seller who refuses a measurement has already given you the answer.
Reputable data sheets separate the values. For the DEWEON 4LD, 6000 W total power and 4000 W at the handpiece are stated separately, and for the PICOLO XL the pulse duration (280 ps) and energy (100 to 3600 mJ) are given in the data sheet. Figures like these can be verified by measurement.
What documents must come with a used laser machine?
It should come with the instructions for use in your language, the manufacturer's declaration of conformity, the rating plate with serial number, maintenance and repair records, and the original invoice as proof of ownership. If these papers are missing, you will run into problems in places nobody thinks of at the time of purchase: with your business liability insurance, during an inspection and when reselling later. Also clarify whether the device is still being financed or leased, in which case it may not belong to the seller. Which documents are required for operation depends on your country.
With a new device from SIACSKIN you buy from the manufacturer, who issues the documents itself, plus specialist training with a training certificate. The TULIX additionally comes with cloud software for documenting treatments.
What are software locks on used laser machines, and how do I recognise them?
Software locks are protection mechanisms by which a device is enabled only for the first owner, for a certain period or for a limited number of shots. Typical examples are passwords for the service menu, licences tied to the original purchaser, handpieces with a chip and a fixed quota, and updates that only the manufacturer installs. A device can be technically flawless and still be out of action after a few weeks because a quota has expired. Have all access data handed over to you and ask the manufacturer in writing whether it will transfer the device to your name.
SIACSKIN states this openly: the TULIX works without consumables and without a shot limit, and the AlexDUAL UFO is designed for up to 100 million shots, with no additional purchase required.
What hidden costs arise after buying a used or cheap laser?
The biggest hidden costs are the replacement of the handpiece or laser source, repairs without warranty and the revenue lost during downtime. Added to these are transport with suitable packaging, set-up and alignment, paid training, suitable protective eyewear, new filters and often a software update. If the device is out of action for 2 weeks because a part is missing, entire courses are delayed, and some clients do not come back. Add these items to the purchase price before you compare.
With a new device from SIACSKIN, installation by the company's own technicians and training are included free of charge, plus a 2-year manufacturer's warranty. The DEWEON 4LD has a handpiece for around 100 million shots, which pushes the most expensive item far into the future. You can run your own figures through the price calculator.
Can I still get spare parts and service for a used laser machine?
That depends solely on the manufacturer, and this is exactly what you should clarify in writing before buying. Some manufacturers support only the original purchaser, require a paid inspection from second owners or have discontinued the model series. With devices that have no identifiable manufacturer there is often nobody to supply handpieces, power supply units or circuit boards, and then a single defective part decides the fate of the entire device. Give the manufacturer the serial number and ask about the delivery time and price of the most important wear parts.
SIACSKIN is itself the manufacturer and offers lifetime support and regular maintenance. Spare parts and consumables are generally available within a few days, by express delivery if required. How the service works is described on the Service, Maintenance and Warranty page.
Do I still have a warranty on a used laser machine?
Usually not: with used devices the manufacturer's warranty has generally expired or is tied to the first purchaser. Anything the seller promises you beyond that is set out solely in the purchase contract. So get it in writing whether any remaining warranty exists, whether the manufacturer will transfer it to you and which parts are excluded. Wear parts such as the handpiece, lamp or cartridge are almost always excluded, although they are precisely the expensive ones.
SIACSKIN gives a 2-year manufacturer's warranty on new devices. In the event of a defect, the device is repaired or replaced under the statutory liability for defects and the warranty. The details are set out on the Service, Maintenance and Warranty page.
When you buy a used device, nobody trains you at first, and you have to organise and pay for the induction training yourself. At best the seller shows you how to operate the device, but not how to choose parameters by skin type, nor the contraindications, nor what to do in the event of side effects. Ask the manufacturer whether it trains second owners, or look for independent training for precisely this technology. Without proof of training, things become difficult with your business liability insurance, and mistakes in the first few weeks cost you clients.
At SIACSKIN, comprehensive training is included free of charge with the purchase of a device: specialist training at handover or on site in your studio, access to the online training platform with video tutorials, and a training certificate. Further training is offered by the SIAC Akademie.
What is the resale value of a laser machine, and what does it depend on?
The resale value depends above all on whether the manufacturer still supports the device and how much service life remains in the handpiece or laser source. There are no fixed percentages. Buyers pay for verifiable remaining service life, complete documentation and an unbroken maintenance record. A device without papers, without spare parts or with locked software is barely saleable, no matter how new it looks. The technology counts too: systems for in-demand treatments such as hair removal find buyers more easily than niche devices.
Anyone who buys new can influence the later value themselves: document maintenance, note the shot count, keep invoices. On the AlexDUAL UFO the crystal is designed for 100 million shots, and the client management system keeps count of the shots. In this way the remaining service life can be documented.
When can a used laser machine still be worth buying?
A used device can be worthwhile if three conditions are met together: its history is fully documented, the manufacturer continues to support the device, and you need it for a treatment with low utilisation. This applies, for example, to a second device with which you are initially just testing a new treatment, or to a recent device from a studio closure that you have inspected by the manufacturer. Even then the price should be far enough below the new price that a replacement of the source would still be covered.
For the device your revenue depends on, the risk is usually too great. If it is only a matter of a low entry cost, there are new devices with a small instalment: the PICOLO S from approx. €130 per month, the VCL DERMALIGHT from approx. €190 per month.
Why are some laser machines so much cheaper than others?
The price difference lies in the parts you cannot see from the outside: laser source, cooling, power supply unit and optics, plus development, testing and service. A source with a short service life, cooling that is sufficient only for short treatments and a power supply unit with no reserve lower the price considerably. Savings are often also made on what counts after the purchase: documentation, training, spare parts stock and technicians. A low price is not a defect if the seller can substantiate performance, service life and service. If they cannot, you are buying the risk along with the device.
Verifiable specifications look like this: the AlexDUAL UFO works with compressor cooling and 4-fold cooling without an external cooling unit, with spots of 10 to 40 mm and a crystal for 100 million shots.
Buy a used laser for cash or lease a new device: which is more likely to pay off?
In most cases the leased new device pays off, because it preserves your liquidity and the manufacturer's warranty applies in the first 2 years. When you buy a used device for cash, you tie up capital in one go and bear every repair yourself. As a guide, the leasing instalment at SIACSKIN is around 1% of the net price per month over a term of 60 months, plus VAT and subject to creditworthiness. The DEWEON 4LD is available from approx. €470 per month.
Set against this instalment what the device brings in per month: divide it by your contribution margin per treatment, and you will know how many sessions per month are needed to cover it. With a used device you additionally plan a reserve for the handpiece and repairs. In the SIACSKIN price calculator you can compare both routes using your own figures.
What questions should I ask every seller of a laser machine?
Ask every seller the same questions and get the answers in writing. Who built the device and who repairs it? How many shots is the laser source designed for, and what does its replacement cost? What power arrives at the handpiece, and is it measured on site? How quickly are spare parts available? What does the warranty cover and what does it not? Are installation and training included in the price? Are there software licences, shot quotas or other follow-on costs? Can I speak to two businesses that have been using the device for more than a year?
If a seller is evasive, that is the most important answer. SIACSKIN responds to enquiries within 24 hours, and in the free consultation you go through these points on the specific device, for example the DEWEON 4LD or the FRACO CO2 XL.
Why is buying directly from the manufacturer safer than buying via platforms or dealers without service?
When you buy directly from the manufacturer you have a single point of contact who built the device, can repair it and stands behind the warranty. With sales platforms and dealers without their own technical team, responsibility is split: the seller refers you to the manufacturer, the manufacturer to the seller, and your device stands idle. Parts and expertise first have to be sourced, and demonstration, installation and induction training are frequently missing altogether. So ask who specifically will come in the event of a fault and where the parts come from.
SIACSKIN is a manufacturer and sells to more than 140 countries. Installation is carried out by SIACSKIN technicians free of charge, training is included, and lifetime support is provided as well. Devices such as the AlexDUAL UFO and the EUPHEUS M8 are developed and built in Germany.
