Laser and Energy-Based Treatments

Unpacking the facts.

Quick Navigation

What are Laser & Other Energy-based Devices Used For?

Laser and other energy-based treatments are commonly used in cosmetic medicine to improve skin tone, reduce pigmentation, treat redness, remove hair, or tighten skin. While these treatments can be effective, they are also powerful, and must be used safely and responsibly.

Lasers and other Energy Devices use very powerful and highly focused light or other electromagnetic radiation to target specific skin concerns like pigmentation, veins and redness as well as sun damage and wrinkles.

There is a vast array of different devices on the market, each heavily marketed to persuade individuals to choose one ahead of the others.
It is important to choose a practitioner who will see throught the hype and spin to give you clear, unbiased, informed advice about your various options.
In New Zealand, anyone can currently buy and use a laser or energy device, even if they are not medically trained. That’s why it’s so important to choose a provider who is properly qualified and accountable.

What Are Energy-Based Devices?

Energy-based devices include:

  • Laser machines for pigmentation, scarring, or hair removal
  • IPL (Intense Pulsed Light) for skin tone and redness
  • Radiofrequency (RF) and ultrasound for skin tightening
  • LED and plasma treatments for rejuvenation

These devices work by delivering focused energy into the skin to stimulate changes like breaking down pigment, encouraging collagen, or heating tissue.

Are These Treatments Regulated in New Zealand?

Currently in New Zealand:

  • Anyone can own or operate a laser or energy-based device
  • There are no licensing requirements for devices or clinics
  • There is no legal minimum level of training to perform these treatments

While this may change in future regulations, the best way to protect yourself now is by choosing a qualified provider.

How to Choose a Safe Provider

NZSCM recommends choosing a provider who:

  •  Has recognised training and qualifications relevant to the device and treatment being offered
  • Has completed formal safety training in energy-based devices they use
  • Works in a clinical setting with strong hygiene and safety standards
  • Uses evidence-based treatments and reputable, well-maintained equipment
  • Provides a proper consultation, explains risks and benefits, and obtains informed consent before any treatment begins

Patients can trust that NZSCM-accredited doctors as they have had thorough, assessed training across all of these domains. 

What Is Safety Training for Laser and Energy-Based Devices?

Safety training teaches health professionals how to use laser and energy-based devices responsibly and minimise risks to both patients and staff. It typically includes:

  • Understanding the science behind laser, IPL, radiofrequency (RF), ultrasound, and other technologies
  • Proper operation, calibration, and maintenance
  • Eye and skin protection protocols
  • Use of personal protective equipment (PPE)
  • Emergency procedures and complication management

In New Zealand, this training is not currently required by law. However, under the Health and Safety at Work Act 2015, all clinics and employers (PCBUs) must ensure workers are adequately trained in the safe use of any hazardous equipment including lasers.


NZSCM strongly recommends formal, recognised safety training for anyone using these devices. All NZSCM-accredited doctors are required to complete laser safety training as part of their NZSCM postgraduate Diploma in Cosmetic Medicine. This training follows the national safety guidelines in AS/NZS 4173:2018, ensuring our doctors understand how to use energy-based devices safely and effectively. 

What Questions Should I Ask Before Getting Laser or Enegery-based Device Treatment?

Before undergoing treatment, you can ask:

  • What training have you completed for this device?
  • Are you certified in laser and energy-based device safety?
  • What is your experience with this specific treatment?
  • A qualified and ethical practitioner will welcome your questions.

What Are the Risks?

While many laser and energy-based treatments are safe when performed by trained professionals, risks can include:

  • Redness, swelling, or mild discomfort
  • Temporary or permanent pigment changes
  • Burns or scarring (in rare cases)

These risks are more likely when treatment is done by untrained or unregulated providers.
