Looking to Acquire or Upgrade Your Hair Removal Laser?
Then read carefully, as this information may help you make the right decision. With numerous brands and technologies available, it’s challenging to choose, let alone make the best choice. Our expert shares their knowledge, listing the questions you should ask and the answers you should seek.
CHAPTER 1: Alexandrite/Nd:YAG Laser Technology
While IPL or diode lasers are used for laser hair removal treatments, Alexandrite/Nd:YAG laser technology is the most widespread and commonly used. Without delving into user preferences for one technology over another, we provide a quick analysis of the advantages and disadvantages of this technology and the key questions to ask to make the right choice!
In Brief:
Advantages:
- Suitable for ALL skin types (I to VI)
- High efficiency with the wavelengths offered
- Speed and ergonomics
- Versatility (possible vascular treatments)
Disadvantages:
- High maintenance cost
- Consumables (lenses/flash lamps)
- Bulkiness and noise
What You Need to Know:
I. TECHNICAL CHARACTERISTICS
- Is the handpiece heavy or light? Does its weight change with options (cooling system, temperature sensor, built-in smoke extractor)?
- Expert Opinion: The weight of the handpiece is crucial, especially for lengthy laser hair removal sessions (e.g., full legs and back).
- To change wavelengths or spot sizes, do you need to power off/restart the machine? Do you need to change the handpiece, fiber, or perform other manipulations?
- Expert Opinion: Additional manipulations will cause time loss and, in multi-user clinics, increase the risk of handling errors, leading to potential breakdowns.
- What spot sizes are included in the price or optional?
- Expert Opinion: Large spot sizes are important for comfort but are sometimes optional—check carefully!
- What is the maximum power of the machine? What is the minimum pulse duration?
- Expert Opinion: Power is critical as it determines the ability to treat fine hairs (vellus). Note that power isn’t the only important factor; the construction of the pulse itself is crucial (Gaussian spot? Pulse train? Flat pulse?). The combination of these technical characteristics determines the machine’s actual effectiveness. Some lasers have automatic calibration, while others do not.
- What is the maximum firing frequency?
- Expert Opinion: This determines how quickly you can treat large areas. However, this frequency must be combined with high energy; not all lasers can deliver homogeneous energy with each repetition.
- Is the handpiece ergonomic?
- Expert Opinion: Beyond the machine’s reputation and power, ergonomics are very important. Is the trigger button well-positioned? Does it have a skin roller? Automatic firing? Built-in thermometer? Pedal, etc.?
- Does the laser offer skin protection through cooling?
- Expert Opinion: There are three possibilities, each with its pros and cons:
- Cryo air cooling like “Zimmer”
- Spray cooling: “canister”
- Contact cooling system, known as “Peltier”
- Consider noise, consumables, bulkiness, efficiency, and comfort when making your choice.
- Is Nd:YAG necessary for your hair removal treatments?
- Expert Opinion: Depending on your region’s climate and sunlight, Nd:YAG may be essential. Its technical characteristics will be important.
- Can Nd:YAG be used for vascular treatments as well?
- Expert Opinion: Nd:YAG’s technical specifications are crucial for vascular treatments and should not be overlooked.
II. PRICE
What is the price of the machine, maintenance service, and replacement parts? What options are available? What warranties are offered? Is an extended warranty available? What is covered by the warranty? Are consumables needed (lamps, lenses, canister, fiber, etc.)?
- Expert Opinion: High-quality lasers, depending on their brand, generation, and reputation, range from 55,000 to 90,000 euros*.
*Prices vary based on negotiations, options, and warranties.
