Diode vs Alexandrite Laser: Clinic Buyer Guide

On our figures the diode machine is cheaper: the Alma Soprano Ice Platinum lists at about €85,000 new, against about €95,000 for the alexandrite-based Candela GentleMax Pro. Used, the ranges overlap heavily, so the real decision is skin types, running costs and how your clinic works.

What are the two machines we can compare?

Our database holds one representative of each technology, so we compare those rather than the technologies in the abstract.

Alma Soprano Ice Platinum is a triple-wavelength diode (755/810/1064nm) with SHR in-motion delivery. Our Soprano page calls it the workhorse in many Irish clinics: it treats all skin types, with a virtually painless protocol.

Candela GentleMax Pro is a dual-wavelength alexandrite (755nm) plus Nd:YAG (1064nm) system. Our GentleMax Pro page describes it as the gold-standard results machine, especially on lighter skin, with single-pulse delivery that rewards operator skill.

Both therefore carry a 1064nm Nd:YAG-class wavelength for darker skin. That makes the "diode versus alex" labels a little misleading for these two models. The differences come from delivery method and consumables more than from wavelength alone.

Figures side by side

New, the gap is about €10,000. Used, at the mid-points, the alexandrite unit is about €5,000 cheaper, and the ranges overlap between €30,000 and €50,000. That means condition, age and what is included will matter more than which laser it is.

What do diode and alexandrite cost to run?

This is the part that catches clinics out.

• Soprano: minimal consumables (gel). The cost to plan for is the handpiece, which is the lifed part. Ask how many pulses are left on it and what an exchange costs. Our page mentions an exchange programme.
• GentleMax Pro: cryogen is used on every pulse, so a busy clinic has a cryogen line in its monthly costs. We do not have a verified cryogen price, so ask Candela for one and multiply by your expected pulse volume. Our page recommends service contracts.

The arithmetic you should do for each: expected treatments per month, pulses per treatment, consumable cost per pulse, and handpiece replacement cost divided by remaining pulses. That is worth more than any list price.

Which laser suits your clinic?

• Mixed skin types, high volume, comfort-first marketing: the diode platform's all-skin-type, low-discomfort profile is why it is common in Irish clinics. A busy clinic that wants therapists treating large areas quickly leans this way.
• Lighter-skinned client base, results-focused positioning: the alexandrite machine is the reputation choice on our page, though single-pulse delivery depends on operator skill, so staff training matters.
• Skin-type claims: do not rely on a brochure. Ask each manufacturer for the indications and settings for each skin type, and talk to your insurer and the HPRA about operator qualifications and safety requirements.
• Resale: both score top demand, and both have established used markets, so either should resell. Check service history before paying, as the figures above are wide.

What should you check before buying either machine?

1. Handpiece pulse count remaining, and the cost of replacement or exchange.
2. Last service date, the engineer who did it, and any contract that transfers.
3. Test treatments on a sample surface to see consistent output.
4. Training and insurance: confirm what your insurer needs before you treat patients.
5. Whether the seller will allow an engineer inspection before payment.

Where can you browse or list used laser machines?

Both machines appear on the used market at wide price ranges, so look at several before deciding. Browse used units in the classifieds. If you are upgrading from one technology to the other, list your current machine free, no commission, and see the seller guide for what buyers check.

Prices vary, so get written quotes and inspect any used unit before paying.

Frequently asked questions

What is the best laser hair removal machine for a clinic?

There is no single best machine; it depends on your client skin types, volume and budget. Both machines here score 5 of 5 for demand on our pages, so compare handpiece life, cryogen or gel costs and local service before price. Our best laser hair removal machine guide goes through the decision.

Are all laser hair removal machines the same?

No. They differ in wavelength, pulse delivery, cooling and consumables. Candela lists alexandrite at 755nm and diode at 800 to 810nm, and the Soprano here is a triple-wavelength diode with in-motion delivery, so the labels do not tell the full story.

Which skin types suit diode and which suit alexandrite?

Sources give different cut-offs: Candela lists alexandrite for Fitzpatrick I to IV and diode for I to VI, while Milan Laser describes alexandrite for I to III, diode for II to IV and Nd:YAG for IV to VI. Both are commercial sources, so ask the manufacturer for written settings and check with your insurer.

Is diode or alexandrite cheaper to buy?

On our machine page figures the Soprano diode lists at about €85,000 new against about €95,000 for the GentleMax Pro. Used ranges overlap at €30,000 to €55,000 and €25,000 to €50,000.

Which has higher running costs?

The GentleMax Pro uses cryogen on every pulse, so a busy clinic carries that line monthly. The Soprano uses mostly gel, but its handpiece is the lifed part. Get consumable and exchange costs in writing.

What happens to a laser's value over time?

We have no completed-sale data, but both machines score top demand on our pages, which usually helps resale. Service history and remaining handpiece life are what move the price within the wide used ranges.

What should I ask a seller about a used hair removal laser?

Ask for remaining pulses on the handpiece, the last service date and engineer, and whether any service contract transfers. Request a live test and an engineer inspection before paying.

Can I list my laser hair removal machine for sale?

Yes. You can list it free on the classifieds, with no commission, and the seller guide explains what buyers ask for.
