Ask the Expert: Which is better for you, the Tria 4x or ViQure EpiPro?


Unlike most at-home hair removal machines, the Tria 4x and ViQure EpiPro use diode lasers rather than IPL. Diode laser is one of the only four lasers used by physicians for in-clinic laser hair removal.[1]

The Tria 4x deserves credit for pioneering the use of diode laser for at-home hair removal. With an energy fluence of 7-22 J/cm², it stands as one of the most powerful at-home laser hair removal systems available.[2]

However, one of the major challenges with the Tria hair removal is that it can be painful to use. It also has the same limitations as an ordinary IPL device, and can only work on light skin and dark hair.[3]

Its tiny window size is also incredibly inefficient on large areas like the arms and legs. And with just 90,000 pulses and 300 battery recharges, it has a limited service life compared to the latest devices that average 300,000.

While its diode laser technology delivers powerful hair removal, the Tria 4x, unfortunately, hasn't evolved past its limitations.

In comparison, the ViQure EpiPro is a diode laser device that not only matches the Tria 4x in terms of energy fluence (Max 20 J/cm²) but also surpasses it in versatility and product design. With its advanced cooling technology, this device provides a virtually pain-free hair removal experience.

The ViQure EpiPro is also made for both home and commercial use. It therefore boasts a more comprehensive set of controls, allowing users to customize treatment settings to their preference. This device can be used on all skin tones, all hair colors, and all body parts–something no other IPL device can do.

Its larger spot size and ergonomic design also contribute to better product build and ease of use. This makes hair removal more efficient. And with a staggering 5,000,000 pulses, it's a robust device that can last you a lifetime.

The ViQure EpiPro‘s ability to strike a balance between power, versatility, ease of use, and comfort makes it an excellent choice for professionals who need a reliable and efficient device for their salons and those who want to do hair removal at home.

Laser Hair Removal Key Comparison: ViQure EpiPro vs Tria 4x

For laser hair removal to be effective, both professionally and at home, consistency and commitment are essential.[8]

It is important to damage your unwanted hair gradually during each session. Your hair will eventually become so thin and sparse that it is negligible or cannot grow back.

The process must be repeated safely, effectively, and consistently in order to produce permanent results.

Laser hair removal at home requires effort and patience, so choose a product that is effective and makes you feel comfortable.

Keeping up with your treatment requires enjoying and wanting to use the product.

To help you make an informed purchase decision, we have detailed our experiences with both products below.

Product Design & Our Experience

Product Build and Design

The ViQure EpiPro is comprised of two parts: a compact console that houses its main components and a handpiece. The main console is quite heavy, but the handpiece is very lightweight and easy to hold and maneuver. The thick cord that connects them both is a generous 6.56 feet. This ensures that you can work comfortably even when treating hard-to-reach areas of your body.

The Tria 4x has all its components in one unit. It holds a miniature diode laser machine inside and lithium-ion batteries, which makes it hefty to handle. This is one of the heaviest home devices we've reviewed, especially compared to most IPL devices. However, it does feel balanced in your hands once you have it in a solid grip. It’s cordless as well, which can be freeing if you don’t mind the weight.

Both devices are built with durable materials, and should withstand years of regular use without significant wear and tear.

However, keep in mind that the ViQure EpiPro was also built for commercial use. Professional machines often feature robust construction made to withstand heavy and frequent use in salon settings. ViQure also specializes in medical grade products as a brand.

Winner: ViQure EpiPro


Diode Laser (vs. IPL)

Most at-home laser hair removal devices rely on Intense Pulsed Light (IPL) or variations of it for hair reduction.[14] Both the ViQure EpiPro and Tria 4x, however, use diode lasers.

When comparing diode laser technology to Intense Pulsed Light (IPL) for hair removal, both have their own advantages and considerations. IPL devices, for instance, use quartz lamps. These are cheaper to produce and more affordable for consumers. Diode lasers are much more expensive to manufacture but are highly regarded for their potency and effectiveness compared to IPL.[15]

A few reasons why diode devices like ViQure EpiPro and Tria 4x are considered more effective than the majority of IPL devices on the market:

  1. Targeting Specific Wavelength – Diode lasers operate at a specific wavelength (e.g., 808nm, 810 nm). This targeted wavelength is highly absorbed by melanin, the pigment responsible for hair color, and allows for precise targeting of hair follicles. In contrast, IPL devices emit a broad spectrum of wavelengths, which can make it less specific in targeting hair follicles. The ability to focus on a specific wavelength makes diode lasers potentially more effective at delivering energy to the hair follicles.
  2. Energy Concentration – Diode lasers concentrate their energy into a single wavelength, allowing for more efficient and effective hair removal. The concentrated energy helps to precisely target the hair follicles while minimizing damage to the surrounding skin. IPL devices, on the other hand, emit a range of wavelengths, which results in less concentrated energy being delivered to the hair follicles. This can potentially reduce the effectiveness of IPL in hair removal.
  3. Higher Energy Levels – Diode lasers can typically deliver higher energy levels compared to IPL devices. Higher energy levels are often associated with better results in hair removal, as they can provide more effective heating and damage to the hair follicles. IPL devices may have limitations in delivering higher energy levels due to the broader range of wavelengths they emit, which can result in less effective hair removal.
  4. Professional-Grade Performance – At-home diode laser devices like ViQure EpiPro and Tria 4x are designed to provide professional-grade performance, with technology and power similar to those used in salon or clinic settings. This higher power and precision make them more effective in reducing hair growth and delivering long-lasting results. Many IPL devices available for at-home use may not have the same level of power or precision, leading to potentially less effective outcomes.

By delivering higher energy levels and concentrating that energy on the hair follicles, devices like the ViQure EpiPro and Tria 4x can achieve better results in inhibiting hair regrowth over time.[16]

References: ViQure EpiPro – Product Technology, Tria 4x – Technology: Product Specifications

Energy Fluence (Laser Power) & Pain Levels

Laser Hair Removal Device:Max Power / Energy Fluence:
ViQure EpiProMax 20 J/cm²
Tria 4x6-22 J/cm²
Silk'n Infinity2.5-4 J/cm² + 70-400 microampere (µA) Galvanic Current
JOVS Venus Pro1 – 6 J/cm²
Ulike Sapphire Air+19.8 J / 6.022 J/cm²

In laser hair removal treatments, energy fluence plays a crucial role in determining the procedure's effectiveness.

Higher energy fluence levels can target and destroy hair follicles better, leading to better and longer-lasting hair reduction results. However, using very high energy levels can also increase the risk of discomfort or adverse effects, so finding the right balance is critical.

On the other hand, using lower energy fluence levels might make the treatment more comfortable, but it could potentially reduce hair removal efficacy since it may not adequately damage the hair follicles to prevent regrowth.

So, choosing an appropriate energy fluence level is essential for laser hair removal. This is to achieve both effective hair reduction and a tolerable treatment experience for the patient.

Due to their use of diode lasers, Tria 4x and ViQure EpiPro offer the highest energy fluence in the at-home market.

References: ViQure Energy Fluence, Tria 4x Energy Fluence

However, in terms of pain or discomfort, only the ViQure EpiPro offers several cooling mechanisms to protect the surrounding skin and minimize discomfort during the treatment.

  1. Cooling Gel – The procedure calls for the use of a cooling gel that acts as a protective barrier, minimizing overheating risk and ensuring a comfortable experience.
  2. Built-in Cooling System – A dedicated cooling system is integrated into the device, continuously cooling the skin during the treatment session. This prevents discomfort and reduces adverse reactions.
  3. Super Hair Removal (SHR) Technique – The product employs the SHR technique, which delivers lower fluence levels in multiple passes. This approach reduces the risk of adverse effects while maintaining effective hair reduction.

The Tria 4x does not have a cooling mechanism at all, but you can use a numbing cream prior and a cooling gel after to soothe your skin.

Which is Better? Both the Tria 4x and the ViQure EpiPro are designed to be well-tolerated during treatments. However, the ViQure EpiPro‘s cooling mechanism and application of the SHR technique make it stand out as a potentially more comfortable option. This allows for a personalized and gentle treatment experience while maintaining a high energy fluence.

As with any laser hair removal procedure, individual pain tolerance may vary, but overall, both devices aim to provide effective hair removal with manageable levels of discomfort.

Winner: ViQure EpiPro

Spot Size

Spot size refers to the area of skin covered by the laser beam during each pulse in a laser hair removal device.

The ViQure EpiPro features a spot size of 12 mm x 14 mm. This larger spot size allows for a more significant coverage area during each pulse, making the treatment process faster and more efficient for larger body areas.

The Tria 4x has a spot size of 1 cm². While still effective, the smaller spot size requires more passes to cover a larger treatment area. This may take slightly longer during each session.

References: Tria 4x Spot Size/Treatment Window, ViQure Key Parameters: Spot Size

Which is Better? The ViQure EpiPro‘s larger spot size provides an advantage in treatment efficiency. It covers a wider area with each pulse, reducing treatment time for larger body parts. On the other hand, the Tria 4x‘s spot size of 1 cm² is smaller and may require more time to achieve the same coverage.

Winner:ViQure EpiPro

Laser Wavelength

The ViQure EpiPro utilizes a laser wavelength of 808 nm. This wavelength is known for its effective penetration into hair follicles, targeting the melanin pigment responsible for hair growth.

The Tria 4x features an output wavelength of 810 nm, which is also a standard wavelength used in diode lasers for hair removal treatments.

References: Tria 4x Laser Wavelength, ViQure EpiPro Key Laser Wavelength

Which is Better? Both the ViQure EpiPro and the Tria 4x utilize laser wavelengths in the near-infrared spectrum, with only a slight difference in their specific values. Both wavelengths effectively target hair follicles and reduce hair by focusing on melanin absorption.

However, considering their spot size, the ViQure EpiPro with its larger spot size is the better option. The larger spot size allows for more coverage during each pulse, making the treatment process faster and more efficient for larger body areas.

This can result in shorter treatment times and additional convenience for users when compared to the Tria 4x‘s smaller spot size, which may require more time to cover the same area.

Winner: ViQure EpiPro


The Tria 4x is classified as a Class 1 laser, the safest category according to their potential to cause biological damage. It emits laser radiation at non-hazardous levels, ensuring user safety during treatments.

Winner: TIE


There are several at-home laser hair removal devices on the market, but the ViQure EpiPro and the Tria 4x stand out as formidable competitors. While both devices utilize true diode lasers, the ViQure EpiPro rises above as the superior choice, offering a wealth of advantages and enhancements.

TheViQure EpiPro stands out with its wider skin tone coverage, accommodating a broader range of users, including those with darker skin tones that most IPL devices cannot treat. Its versatility extends to all hair colors, including lighter shades, making it a more inclusive option that can be used by anyone looking for effective hair removal.

Moreover, the ViQure EpiPro‘s larger spot size and ergonomic design enhance treatment efficiency and comfort, ensuring smoother sessions across larger body areas. Its advanced cooling technology provides a virtually pain-free experience, setting it apart from the Tria 4x, which lacks such comfort-enhancing features.

While the Tria 4x deserves recognition as the pioneering brand for diode laser hair removal at home, it has struggled to keep pace with newer devices that offer superior cooling mechanisms and overall product design.

In the end, the ViQure EpiPro emerges as the clear winner, combining power, versatility, ease of use, and advanced cooling technology to deliver the most effective and comfortable at-home laser hair removal experience.

From a salon standpoint, the ViQure EpiPro is strategically positioned as an accessible and budget-friendly option compared to high-end laser hair removal machines that come with hefty price tags ranging from $5,000 to $20,000 USD.

While it presents a cost-effective alternative, certain features, flexibility, and power may be limited compared
to larger, more expensive equipment. To maximize results, it is advisable to utilize the highest intensity setting possible.

On the other hand, when used as an at-home laser hair removal and skin rejuvenation device, the ViQure EpiPro truly shines.

Unlike many IPL devices available, this product excels with its diode laser technology, offering remarkable effectiveness and precision. It proves compatible
with all skin types and various body parts. This includes areas that are typically off-limits for at-home IPL devices, such as above the cheekbones and a full Brazilian.

Its exceptional durability and a wide range of parameters resemble professional-grade machines, all neatly packed into a portable and user-friendly design. Even beginners can comfortably and conveniently operate the device.

While the ViQure EpiPro‘s price point may be higher than regular handheld IPLs, the superior performance and foolproof nature of this at-home laser hair removal device make it a worthwhile investment for those willing to spend extra.

As an experienced esthetician, I wholeheartedly recommend the ViQure EpiPro as the most effective and reliable at-home laser hair removal device available today.

The Tria 4x is recognized for introducing diode laser technology to at-home hair removal. It boasts an energy fluence of 7-22 J/cm², making it one of the most powerful systems available.

However, users have reported discomfort during its use, and it shares limitations with regular IPL devices, being effective only on light skin with dark hair.

The device's small window size makes it inefficient for treating larger areas, and its limited service life of 90,000 pulses and 300 battery recharges falls behind newer devices.

Despite its powerful diode laser technology, the Tria 4x has not yet overcome its constraints, holding back its full potential.

If you're looking for a similar device that uses a diode laser, the ViQure EpiPro has a wider range and more flexible features in comparison.
