Leaseir Alternative: DEWEON 4LD Diode Laser with 4 Wavelengths from the Manufacturer

Leaseir is a manufacturer of diode lasers based in Spain. Its best-known device is the Leaseir MHR platform with interchangeable handpieces (Single, Dual, Quad) up to 3.7 cm²; there is also the portable DS variant. Anyone searching for “buy Leaseir”, “Leaseir MHR price” or a Leaseir alternative usually compares power, spot size, frequency and cooling. The DEWEON 4LD from SIACSKIN combines four wavelengths (755, 808, 940 and 1064 nm) in one handpiece, with 6,000 W at the handpiece, up to 30 Hz, ice sapphire cooling down to –50 °C and SIA AI. Made in Düsseldorf, financeable from approx. €470 per month.

Reading power specifications correctly

Leaseir states 7,300 W electrical power for the Dual and Quad handpieces, SIACSKIN 6,000 W at the handpiece for the DEWEON 4LD. Manufacturers measure and name power differently, so a single wattage figure says little about the result. More meaningful is the interplay of fluence, pulse duration, frequency and spot size. Leaseir states up to 42 J/cm² at 4 Hz, 10 Hz in SHR mode. The DEWEON 4LD works with pulse durations from 1 ms, up to 30 Hz and a largest spot of 6 cm². The best way to compare the devices is in practice: in our showroom in Düsseldorf you can test the DEWEON 4LD yourself by appointment.

Switching handpieces or one handpiece for everything

The MHR platform relies on interchangeable handpieces that, according to Leaseir, you can swap yourself: small spots for precise areas, large ones for legs and back, different wavelengths depending on skin type. The DEWEON 4LD bundles all four wavelengths in one handpiece and only changes the spot size. The SIA AI detects skin and hair type and sets the parameters; the integrated client management documents areas, shots and revenue per client. More on the basics in the article Diode laser hair removal and on the role of wavelengths under Laser wavelengths explained.

When which device fits better

  • Leaseir MHR: if you are looking for a pure hair removal device with interchangeable handpieces and SHR mode and want to work with the Spanish manufacturer or its dealer.
  • DEWEON 4LD: if you want four wavelengths in one handpiece, up to 30 Hz, AI-assisted parameters, skin rejuvenation via SR technology, and service, training and financing from Düsseldorf.
  • Many clients with very dark skin: For this we recommend the AlexDUAL UFO with Nd:YAG 1064 nm, see Diode laser or alexandrite laser.

What always comes with SIACSKIN

  • Manufacturer from Düsseldorf: development, service and spare parts from Germany, CE under MDR.
  • 2-year warranty on the device, onboarding and training through the SIAC Akademie included.
  • Financing through our own partner bank: leasing, rent-to-own, loan or purchase, with no down payment on request, also for start-ups (credit check).
  • Showroom in Düsseldorf: view and test devices on site by appointment.
  • Transparent monthly rate instead of price on request: In the price calculator you can see when the device pays for itself.

Frequently asked questions

Who makes Leaseir lasers?

Leaseir is a medical device manufacturer based in Spain (Leaseir Technologies S.L.U.). It is best known for the MHR and DS diode laser platforms for hair removal.

What distinguishes the DEWEON 4LD from the Leaseir MHR?

The Leaseir MHR works with interchangeable handpieces for 810 nm, 1060 nm or the blend combination 810 + 940 + 1060 nm. The DEWEON 4LD combines 755, 808, 940 and 1064 nm in one handpiece, works up to 30 Hz, has an AI skin analysis and additionally the SR technology for skin rejuvenation.

Which diode laser is faster?

That depends on spot size, frequency, fluence and treatment technique, and manufacturers calculate treatment times differently. The DEWEON 4LD offers up to 30 Hz and a largest spot of 15 × 40 mm. A test in the showroom is the most meaningful.

Can I lease a diode laser with no down payment?

Yes, through our partner bank leasing, rent-to-own or a loan is possible with no down payment on request, also for start-ups. A credit check is required. Example DEWEON 4LD: from approx. €470 net per month for 60 months.

Do I get training with the DEWEON 4LD?

Yes. On-site onboarding is included and is carried out by experts who work with the devices themselves. Through the SIAC Akademie you deepen your knowledge with training courses including a certificate of attendance.
