Key takeaways
- Nd:YAG is a laser that emits at 1064 nm; IPL uses a spectrum of light and is not a laser.
- On dark skin, melanin in the epidermis makes the choice of device, wavelength, and settings especially important.
- Nd:YAG 1064 nm penetrates more deeply and is relatively less absorbed by surface melanin than shorter wavelengths.
- Institut V’s Clarity II combines 755 nm Alexandrite and 1064 nm Nd:YAG; the consultation determines the protocol for the skin type and hair.
- No technology replaces assessment of the skin, recent tanning, medications, and any history of pigment changes.
What are the technical differences between Nd:YAG 1064 nm and IPL?
Nd:YAG 1064 nm produces one precise laser wavelength, while IPL delivers several wavelengths in a broader spectrum. This difference affects penetration depth, absorption by surface melanin, and how treatment parameters must be selected. IPL systems are not interchangeable: their filters, spectra, settings, and cooling vary by device.
Light-based hair reduction works by heating melanin in the hair. Dark skin also contains more melanin in the epidermis, so some energy can be absorbed by the skin when the technology or settings are not appropriate. Institut V’s Clarity II combines a 755 nm Alexandrite wavelength and a 1064 nm Nd:YAG wavelength. The manufacturer states that 1064 nm penetrates more deeply and reduces interaction with epidermal melanin compared with 755 nm.

| Entity | Attribute | Value to assess during consultation |
|---|---|---|
| Nd:YAG 1064 nm | Light type | Laser with one precise wavelength and deeper penetration |
| IPL | Light type | Broad light spectrum; IPL is not a laser |
| Dark skin | Epidermal melanin | Skin type, recent tanning, and pigment history must be assessed |
| Hair | Pigmented target | Colour, thickness, depth, and treatment area influence response |
| Clarity II | Function | 755 nm and 1064 nm platform with individualized settings |
This comparison does not establish that one device is automatically appropriate for every person. The American Academy of Dermatology notes that hair colour and thickness, the treatment area, laser type, and skin colour all affect results and possible side effects. The laser hair removal for dark skin page explains Institut V’s approach for darker skin types in more detail.
What questions should you ask before treating dark skin?
Before treatment, ask which device and wavelength will be used, how the settings will be adapted to your skin, and how much experience the provider has with your skin colouring. The AAD also recommends discussing expected results, possible side effects, and instructions before and after treatment.
The consultation should cover how your skin reacts to the sun, any recent tan, self-tanner use, medications, a history of scarring or pigment changes, and the characteristics of the hair. Institut V uses this assessment to decide whether treatment is appropriate and to select Clarity II parameters. A fixed session count or identical result cannot be promised before the response of the skin and hair has been observed.

Frequently asked questions
Is IPL a laser?
No. IPL uses a broad spectrum of light, while a laser emits one precise wavelength. Both can target melanin in the hair, but they do not operate or use treatment parameters in the same way.
Is Nd:YAG 1064 nm automatically suitable for every person with dark skin?
No. The 1064 nm wavelength is relatively less absorbed by surface melanin and is commonly selected for darker skin types, but the skin, hair, recent tanning, treatment area, and medical history must still be assessed.
Does Clarity II use only Nd:YAG?
No. Clarity II combines 755 nm Alexandrite and 1064 nm Nd:YAG. Institut V selects the wavelength and settings after assessing the skin type, hair, and treatment area.
