Hair removal can be fun with the right tool. But when you have to repeat a process for months with no visible results, it can be frustrating. Without mincing words, most devices for removing unwanted hair available for sale these days are frustrating. They are either ineffective or dangerous to the skin.

Technologies like IPL and Lasers have tremendous benefits in hair removal as they tend to be permanent in their action. But while IPL is broad-spectrum, lasers are narrow and specific. The two methods, however, require flashing Light beams into the skin to disrupt hair growth from its root. The process can produce a burning sensation in the skin, which can be discomforting, but many manufacturers have found intuitive ways to address this setback.

Silk’n Infinity is an IPL hair removal device, while Tria 4X is a laser device. As such, beyond the individual features of these devices, a clear tabular difference between an IPL and laser modes of hair removal will further help you appreciate what’s unique about them. After this, we concentrate on specific parameters to settle the scores between Silk’n and Tria 4X.

Differences Between Laser and IPL Hair Removal Methods





Nature of Light

Monochromatic, single wavelength, concentrated, and powerful.

Broad spectrum, broad wavelength, and polychromatic, and less powerful light beams than lasers.

A laser produces faster results but with a limited scope than IPL. IPL can be a bit slower but has a broad application scope.

Safety on the skin

The single-wavelength light focuses on its target without invading surrounding cells.

IPL’s weaker lights often deviate from the target (follicle) and get absorbed by surrounding molecules.

Lasers are generally safer for the skin than IPLs.

Sessions required

Requires between six and eight sessions to produce effective results.

Owing to weaker lights with wavering wavelengths, IPL needs between ten and twelve sessions

IPL requires more sessions to produce results than lasers.

Treatment time

Narrow mouths or heads mean lasers release little flashes at a time.

IPL devices generally have broad heads

IPL requires less time to complete each treatment session than lasers.

Painful feel

Stronger lights with concentrated wavelengths increase painful feelings.

Weaker, scattered lights make the pain more manageable.

Lasers can be more painful than IPL.

Treatment cost

Lasers use more advanced technology and machine, requiring more money

IPL machines are relatively more ubiquitous than lasers.

IPL costs less than lasers.

From these comparison points, laser hair removal technology is ahead of IPL, although it is more expensive and may cause painful feelings than the former.

Nevertheless, the specific design of gadgets based on either technology can make the experience different. Stated differently, some IPL devices may outperform many laser handsets because of their manufacturers’ details. That is why we will compare the two products under review based on their features, not just the operating technique.

Silk’n Infinity Hair Removal vs. Tria Laser 4X: Which is Better?

Silk'n vs. Tria Laser 4X Before we head straight to point out the differences between these two hair removal devices, it won’t be out of place to also consider their similarities. It will help to see how close both devices are.

Below are similarities:

  • The makers of both devices offer a 60 days money-back guarantee. That means that if you do not get satisfactory results within sixty both devices’ close functionalities.

  • Both devices afford free shipping to all locations in the US and Canada.

  • Both devices are FDA-approved.

  • Both offer one year warranty, although Silk’n provides two years warranty for Canadian buyers.

  • Both are electrically and battery-operated.

  • Both have five energy levels.

Now that we have seen where the two devices overlap, it’s time to bring out their differences and see which is better based on them.

Design and Ergonomics: Tria Laser 4X

tria While looks and shapes may not be directly connected to hair removal functionalities, it’s a veritable buying decision by many. Besides, a physically appealing product gives a feeling of money well spent.

Tria laser combines pink, white, and black to produce an attractive device even from afar. But that’s not all; its long handle affords a firm grip that will not bore the holder regardless of how long they hold it. There are also two vents on the anterior part that helps the device dissipate heat and keep it cool while treatment lasts.

Silk’n Infinity hair removal handset isn’t bad, either. Its compact nature makes it a traveler’s delight, but many people complain that handling it is awkward. That is probably because of its broad middle and rounded end, making it a handful.

Therefore, Tria looks more attractive, well-designed, and easier to handle than Silk’n.

Cost of Device: Silk’n Infinity Hair Removal

As pointed out earlier, laser hair removal technology is more expensive than IPL. This observation plays out with these two devices as Tria Laser 4X costs $499, while Silk’n goes for $321.72 after discounts. Without any price slash, Silk’n costs $429, which is still not up to the $499 price tag of the laser device.

Of course, this price difference is significant for anyone with a tight budget and is a strong purchasing consideration considering both devices’ close functionalities. Or why should I spend an extra $170 on a machine when I can get its substitute for less

Energy Density: Tria 4X Laser

The energy density of a laser or IPL hair removal handset indicates the number of light beams that hit the hair follicles per time. Generally, the more this number, the faster it is for you to notice results.

Silk’n Infinity advanced IPL handset produces 4 joules/cm^2, while Tria 4X laser produces 20 Joules/cm^2 of energy. This energy difference implies that Tria is at least four times faster in action than Silk’n.

Combining this with Tria’s precise light wavelength, Silk’n is no match for Tria’s speed at eliminating excessive or unwanted hair.

User-Friendliness: Silk’n Infinity IPL Device

Silk'n People who use hair removal gadgets have other things to attend to besides this beauty routine. Therefore, it is not uncommon for them to forget the next treatment date or time. Part of what sets any gadget apart is the ability to understand this peculiarity and others and solve It.

Silk’n has an app that reminds its users of their next treatment date and other details. It also has a quartz bulb that reloads and pulses faster than most other IPL devices and even Tria lasers.

Therefore, it’s slightly more user-friendly than Tria, which only features a sensor to detect skin compatibility.

Time to Complete a Session: Silk’n Infinity IPL

Nobody jokes about the speed in this century; we want to be able to get things done quickly. Unfortunately, Tria laser 4X cannot guarantee a speedy completion of a complete body treatment because of its narrow head. Besides, it doesn’t allow gliding like Silk’n and other IPLs do.

Therefore, if you would like your hair removal device not to take more than ten minutes to complete its job, you should be thinking about Silk’n. Its broad head and an option to glide ensure you can cover your legs, arms, and armpit in ten minutes or less.

Faster Results Timeline: Tria Laser 4X

While completing a session with Tria laser 4X may take longer than Silk’n, the results timeline is faster than Silk’n. From the earlier explanation, it’s easy to understand why. Laser lights are of a single wavelength, precise, and of higher energy than IPL. The 4X of this product refers to its energy density which is four times that of most IPL devices.

Therefore, if you have tried other hair removal methods or devices and haven’t got a satisfactory result or the result is usually delayed, Tria Laser 4X is a better option. It produces a clean, smooth treatment in four weeks instead of the six weeks of most IPL handsets.

Bottom Line

Tria 4X Laser hair removal is more efficient and effective at removing unwanted hair from body parts than Silk’n. Its energy density is superior; its design is better, just like it leads to delivering faster results. However, its high price and more prolonged treatment time because of its narrow head are no minor setbacks. In all, one can give it to the Tria 4X laser as being better than Silk’n.

A Better Choice

As good as the two devices are, none seriously did something substantial to ease the pain that inevitably occurs during treatments. This neglect implies that users may experience hyperpigmentation, discomfort, scarring, and other side effects during or after treatments. It also means people with sensitive skin cannot safely use either of the two handsets.

If you want something more encompassing, I recommend Ulike Sapphire Air3 IPL Hair Removal Handset . Besides its strong emphasis on painless treatments, it has other benefits Silk’n and Tria do not have. Here are those benefits:

  • Ulike offers two years hassle-free warranty on its IPL handset.

  • Instead of the 60 days money-back guarantee offered by Silk’n and Tria, Ulike provides 90 days.

  • Results are much faster with this Ulike handset than the two devices. You start seeing hair reduction in just three weeks.

  • Owing to its broad head and gliding feature, this purple handset completes full body treatment in ten minutes or less.

  • Its patented icy-pain reduction technology is simply unmatched. Because of this, you can use it anywhere on your body, including the face.

  • It has better accessories and offers excellent value for the money spent. For instance, you will find an eye-protecting goggles and a beauty pouch in the box for enhanced usage.
