Diode laser hair removal, explained
An overview of the treatment, how it works, and what to expect. Full details are covered during your consultation.
True laser technology
We specialise in diode laser hair removal using the EternaQUAD PRO, an advanced four-wavelength diode laser system. Every client begins with a consultation and patch test, so your practitioner can assess suitability before any treatment takes place.


The machine behind your treatment
Laser Essentials uses the EternaQUAD PRO, a professional four-wavelength diode laser system used for hair reduction treatments.
The EternaQUAD PRO combines four defined diode wavelengths — 755, 808, 940 and 1064 nm — to provide a broader and more adaptable treatment spectrum than single-wavelength systems.
Its AI-assisted skin and hair analysis assesses factors such as Fitzpatrick skin type, hair colour and hair density. This information supports the qualified practitioner when selecting suitable settings and wavelengths for each individual treatment plan.
Technology supports the treatment, but suitability is always determined through professional consultation and patch testing.

Four wavelengths. One personalised approach.
Laser Essentials uses the EternaQUAD PRO, an advanced four-wavelength diode laser system combining 755, 808, 940 and 1064 nm technology.
Its broader wavelength spectrum is designed to target multiple chromophores within the hair follicle and support a more adaptable approach across different hair and skin characteristics.
AI-assisted skin and hair analysis assesses factors including Fitzpatrick skin type, hair colour and density, helping the qualified practitioner select suitable settings and wavelengths for each personalised treatment plan.
Technology supports the treatment. Professional consultation determines suitability.
The four-wavelength design is intended to:
- Targets multiple chromophores within the hair follicle
- Provides broader light absorption
- Adapts treatment settings for different hair and skin characteristics
- Offers greater versatility across consultations and treatment plans
Why diode laser?
Unlike IPL, which uses broad-spectrum light, the EternaQUAD PRO is a true diode laser delivering four defined wavelengths — 755, 808, 940 and 1064 nm. This provides a more targeted and adaptable approach to professional hair reduction than a single-wavelength diode system or IPL.
A true laser, four wavelengths
The EternaQUAD PRO delivers four distinct diode laser wavelengths, rather than the single wavelength used by many diode systems or the broad-spectrum light used by IPL.
Precision and consistency
Because the light is targeted rather than broad-spectrum, diode laser is commonly chosen for its precision and consistency across a course of treatment.
A popular choice for hair reduction
Diode laser is a more targeted technology than IPL and is a popular choice for clients seeking professional laser hair reduction treatments.
Diode laser is not guaranteed to suit every client or situation, and both results and the number of sessions required vary from person to person. Suitability is always assessed at a consultation, with a patch test, before treatment begins.
AI-Assisted Skin & Hair Analysis
The EternaQUAD PRO combines four-wavelength diode technology with AI-assisted skin and hair analysis. The system assesses factors such as Fitzpatrick skin type, hair colour and hair density to support the selection of appropriate treatment settings and wavelengths.

How it works
- Step 1
Consultation
We start with a consultation to talk through your skin and hair type, medical history, and what the treatment involves, including a patch test.
- Step 2
Treatment plan
Your practitioner will discuss a suggested course of sessions based on your consultation. The number of sessions needed varies from person to person.
- Step 3
Diode laser sessions
During each session, focused diode laser light from the EternaQUAD PRO is directed at the treatment area, targeting the pigment in the hair follicle, with settings and wavelengths adapted to you by a trained practitioner.
- Step 4
Aftercare
You'll be given aftercare guidance to follow between sessions, and you're welcome to ask questions at any stage of your treatment plan.
Where it can be used
- Face — upper lip, chin, cheeks
- Underarms
- Arms — half or full
- Legs — half or full
- Bikini area
- Back and shoulders

Suitability & safety
Common questions
Yes. Laser Essentials provides treatments for women only.
Diode laser is a true laser technology, while IPL uses broad-spectrum light rather than defined laser wavelengths. Laser Essentials uses the EternaQUAD PRO, which delivers four diode laser wavelengths (755, 808, 940 and 1064 nm), offering a more targeted and adaptable approach than IPL and is a popular choice for clients seeking professional laser hair reduction treatments.
Yes. Every new client is required to attend a consultation and patch test before any laser treatment begins, so your practitioner can assess suitability and answer your questions.
This varies from person to person depending on the treatment area and individual factors. Your practitioner will discuss a suggested course during your consultation.
Suitability depends on individual factors such as skin type, hair type, and medical history, which is why a consultation and patch test are required before treatment.
