‘I’ve used this LED face mask for four months and it’s the best thing to happen to my skin’

The dual mask works to treat the face and neck but it doesn’t come cheap

LED masks aren’t a new phenomenon in the beauty industry but new developments set some masks apart from others. How many LEDs the mask has, for instance, can make a difference, as can the frequency at which they emit their near-infrared light.

According to aesthetics specialist Dr Edel Woods, “the number of LEDs isn’t the only factor, the spacing and placement of the LEDs matter, too.” The “more LEDs will usually equal better coverage, so the light can reach more areas,” but “a mask that has evenly spaced lights will usually produce better results” also.

These technical differences separate a £40 mask from a £400 one. Silk’n’s face and neck iteration (£399, Boots.com), for example, has four modes of operation for targeting different skin concerns: anti-ageing, skin brightening and smoothing, oil balancing and acne fighting. You can also buy just the face mask version (£160, Boots.com).

With numerous LED masks on the market – think Currentbody, Dr Dennis Gross and Omnilux – Silk’n’s offering is, on paper, a cut above some of its competitors, but how does it perform in reality? I’ve been using the Silk’n dual LED mask for almost four months, so I can bring you my honest thoughts and let you know whether or not the device is worth your hard-earned cash. Scroll on for my full granular review and verdict.

How I tested

I began testing the Silk’n dual LED mask at the start of October 2024, continuing to use it until 20 January 2025. I documented my testing through all stages of use, including during the Christmas period, which brought with it some bad skin habits (increased alcohol, sugar and fat intake). I noted any breakouts, plumping effects or irritation and recorded how the mask felt and held charge.

For context, I’m 27 years old and have oily skin that’s prone to blackheads and whiteheads and, while I don’t generally suffer with pimples, those same blackheads and excess sebum leave the texture of my skin very rough and bumpy. Of course, having an oily complexion does mean my skin is less likely to show immediate signs of ageing but, again, I’m only 27 and haven’t yet seen any big developments in the fine lines and wrinkles department. The areas in which I did anticipate improvements included the crow’s feet developing around my eyes, the two deep creases in my neck (thanks to my ‘tech neck’ posture) and the concentration of blackheads.

Why you can trust us

As The Independent’s beauty writer, I am not only well-versed on the benefits of LED masks – having met with beauty tech experts such as Dr Alexis Granite and Dr Ahmed El Muntasar – I have also written about various devices for IndyBest (such as Currentbody’s) already. I’m currently in the process of testing more than 10 different LED devices for a wider review, so my opinion of the Silk’n mask is largely informed by my experiences with similar devices from other brands. I’ve been working in the beauty sphere for more than five years and, in terms of cosmetics tech, I’ve covered everything from microcurrent tools to cryo globes.

The mask

This device is essentially two masks that connect (via a two-way adaptor) to a single charger. The charger itself handily features an LED display, to let you know what mode you’re using and how many minutes are left for your treatment. The choice of four treatments plus three strengths did overwhelm me at first. Ultimately, I found myself using mode one most often – it combines three types of light for more of an all-round effect, using red light (frequency: 630nm), dark red light (660nm) and near-infrared light (830nm). For those not familiar with the effects of different light frequencies, it’s recommended red light sits within a 630-670nm (nanometres) range, while near-infrared light should sit within 800-900nm. Nanometers describe the length of the various light waves, with different wavelengths targeting different skin concerns.

Using mode one of the Silk’n mask, I made use of three out of the four treatments on offer, omitting only the blue light option, which works to target acne and acne scarring – something, as mentioned previously, I don’t typically suffer with.

With the red, dark red and near-infrared lights up close and personal with my skin each night, the mask set about smoothing the skin, reducing sensitivity, balancing oil secretion (my main concern, given the clusters of blackheads), brightening, boosting elasticity and working to minimise the appearance of fine lines. A big task, indeed.

If you were hoping to make use of the blue light mode, it actually works a little differently from the other three and emits its 405nm treatment through the handheld power bank. This way, you can target your problem areas directly and, for ease, this fourth mode only persists for three minutes. A quick acne zap and be on your way, as it were.

As for the different strengths available within each mode, they adjust the brightness of the LEDs while maintaining the set wavelengths for the different types of light. In theory, this means brighter LEDs equal a stronger treatment, so, I was curious as to whether this might cause irritation after repeated use.

I found the mask relatively comfortable and enjoyed the addition of a strap towards the top of the head (versus Currentbody’s single back-of-the-head fixing), which helped to prevent any slipping. The neck mask, too, is comfy, so long as you’re not trying to slouch on the sofa – the neck attachment begins to feel more akin to a brace and prevents movement in this area. Then again, the treatment only lasts for 10 minutes.

The results

After seeing a noticeable difference in the visibility of my fine lines with Currentbody’s LED mask, I was keen to see if the Silk’n dual would have the same effect – especially on my neck, as this model comes with an extra wrap-around attachment.

In short, I didn’t see as marked a difference in the state of the fine lines around the two creases between my eyebrows as I did with the Currentbody device. Plus, in terms of the two deeper creases on my neck, I saw no change. Naturally, this left me disappointed, especially considering the device’s £400 price point.

That said, I definitely felt as though my skin looked plumper and less translucent towards the end of the testing period. I’ve always been aware of the see-through appearance of my skin, with things like broken capillaries and dark circles shining through on make-up-free days. However, after 14-plus weeks of using the Silk’n face mask, the visibility of a burst blood vessel had significantly reduced in the time between the two pictures shown below. Moreover, after overwhelming my skin with too many AHAs/BHAs, my complexion was left with red/purple-tinged clusters from the irritation but the Silk’n mask made short work of these and, back in October, after seven days of constant use I could see an improvement.

Dr Woods explained the results I experienced were down the lights, particularly red and near-infrared, because they “encourage collagen and elastin production, which are essential for firmer, plumper skin.” She added that “the more collagen your skin produces, the smoother and firmer it becomes, which will reduce the translucent look and help improve overall texture”. As for the reduction in visibility of blood vessels, she noted that red and dark red LEDs work to boost circulation, so “when blood flow improves, your skin heals better and issues like broken blood vessels or redness reduce.”

Consistency is key with this mask and I certainly saw results drop off if I skipped a few days. In my experience, it took seven days back-to-back to see the first minor changes (as with my patches of irritation) and, after one month, I then began to notice bigger differences. For me, this was centred heavily around the concentration of blackheads on my chin, jawline and the area surrounding my nose. Not only did my skin prove less shine-prone while using the mask (also evidenced in the before/after pictures above), but my blackheads shrunk significantly.

Before using the mask, the pores on my chin had been blocked and visibly full with sebum. This resulted in a rough, bumpy texture that affected my make-up-free skin and the application of my foundation and cream products. After testing, while my pores haven’t vanished entirely, they now look and feel clearer.

To make sure this wasn’t a mere coincidence, I consulted Dr Woods who explained that while the “LEDs don't stop your skin from producing sebum, they help reduce the inflammation that can make pores more likely to clog.” In turn, this “will prevent blackheads from forming.” The near-infrared light “penetrates deeper into the skin and promotes healing and circulation. This can help repair skin issues like clogged pores and breakouts, making your skin look clearer over time.” So judging by her expert knowledge, the LED mask was responsible for my clearer complexion.

Lastly, having suffered from retinol sensitivity and various skincare acids in the past, I’ve learnt that my skin is actually more irritation-prone than I’d initially thought. After using the Silk’n LED mask I felt improvements in that department, too, and I was able to increase my weekly retinol usage, without any flaking or stinging.

The verdict: Silk’n dual LED mask

Overall, after extensive testing, the results of the Silk’n LED mask impressed me greatly. However, I didn’t enjoy the included neck mask as much and felt the results in this area paled in comparison to those on my face. To add to this disappointment, Silk’n’s single LED mask isn’t actually as powerful as the one featured in the dual package and features both a longer 15-minute treatment time and no near-infrared light. So, the question is: is the mask alone worth £399? I think it is. Currentbody, Omnilux, Dr Dennis Gross and Foreo – to name a few – all list their LED masks for around the same price, if not higher.

I enjoyed the Silk’n mask’s variety of light options and intensities (something that competitors Currentbody and Omnilux don’t offer) and saw proven results in line with the red, dark red and near-infrared light I used. The mask is comfy, boosts the performance of your existing skincare formulas and is infinitely reusable.

What’s more, it’s worth noting that, as a 27-year-old tester, I perhaps wasn’t the prime market for testing the neck mask, without any loose skin or major fine lines (bar those from tech neck) to speak of.

Granted, this mask is an investment but if you have the expendable income and are conscious of skin sensitivity, elasticity and feel, I think it’s worth the splurge – it’s certainly the best thing to happen to my skin in a long time.
