The Ultimate Guide to Choosing an LED Mask in 2025
What really matters, how LED masks work, and how to pick one that is worth your money?
LED masks have exploded in popularity over the last two years. From social media to skin clinics, it feels like everyone is talking about LED therapy. But with dozens of brands on the market, huge price differences, and very little transparency, it can be incredibly confusing to know which LED mask is actually worth your investment.
If you are looking for the best LED mask in Ireland, or you simply want to understand what LED masks really do and how to choose the right one, this guide will walk you through everything you need to know.
What does an LED mask actually do
LED light therapy uses specific wavelengths of light to support natural skin functions. Different colours target different concerns, helping with radiance, clarity, evening tone, fine lines, visible redness, and more.
The light energy penetrates into the skin layers where it is absorbed by cells, encouraging healthier looking skin over time. Consistency is key. Most women use LED therapy three to five times a week for ten to fifteen minutes.
But here is the important part.
Not all LED masks are equal!
The truth no one tells you: wavelength alone does not matter
Most LED mask brands only talk about wavelengths.
And yes, wavelengths are important. They tell you which colour you are getting and what type of skin concern the light supports.
But wavelength is only one part of the story.
The real question is:
Is the light strong enough to reach the skin layers where it actually works?
That brings us to the most important specification that many brands never mention.
The specification that actually matters: irradiance
If you want an LED mask that genuinely works, you must look at the irradiance.
Irradiance is the power output of the LED lights, measured in mW per cm².
It tells you two things:
-
How strong the light is
-
How deeply it can reach the skin
Without enough irradiance, the session may look bright but the light does not penetrate into the deeper layers where it needs to reach.
This is the biggest reason why some masks produce visible results and others feel like nothing is happening.
When searching for an LED mask, always ask:
✔ What is your irradiance
✔ Do you list it clearly
✔ Are you transparent about your specifications
• Under 20 mW/cm²: too weak for meaningful results
• 20 to 35 mW/cm²: moderate, gentle, entry level strength
• 35 to 45 mW/cm²: strong, effective, and ideal for visible at home results
If a brand does not list irradiance, you have no way of knowing what you are paying for.
Why many LED masks fail (and how to avoid choosing one that will disappoint you)
Here are the most common problems on the market:
• Weak irradiance
• Overpriced luxury branding with little performance
• Very short treatment times that cannot deliver results
• No transparency on specifications
• Only face masks, with no option for neck or chest
• Uncomfortable design
• Low number of LEDs
When you are investing in your skin, you deserve more than that.
What to look for when choosing an LED mask
If you want an LED mask that actually delivers results, look for:
✔ Strong enough irradiance (the most important factor)
✔ Clear transparency on all specifications
✔ Multiple light modes for different skin goals
✔ Comfortable fit
✔ Durable materials for long term use
✔ A fair price that reflects performance, not branding
✔ Options for face, neck, and chest
✔ Safety certifications
✔ Trusted retailer or Irish based company
When you compare LED masks using these factors, the difference between brands becomes noticeably clear.
Why Lerelle Beauty LED masks stand out
Lerelle Beauty masks were created because of one simple frustration.
There were no LED masks on the market that were:
• powerful
• transparent
• fairly priced!!
• and designed for long term performance
So after more than a year of research, design, testing, and refining, the masks were built with everything customers wish existed.

Here is what makes them different.
1. Strong irradiance for real performance
We clearly list our irradiance so you know exactly what you are investing in.
The masks are designed with powerful enough light to reach deeper skin layers so your time and consistency actually produce visible results.
Many brands skip this information.
We highlight it.
2. Seven light modes
Each mode supports different skin goals, including radiance, clarity, balance, brightness, visible fine lines, and calming redness.
3. Full transparency
No guesswork.
Every specification is listed clearly because you deserve honest information.
4. Three mask options to suit every woman
• LED Face Mask
• LED Neck and Chest Mask
• Full Therapy Set (Face, Neck, Décolletage)
Most brands offer only face masks.
But your neck and chest age faster than your face, and they deserve just as much care.
5. Fair pricing without luxury mark ups
Many LED masks are extremely overpriced for no reason except branding.
Lerelle Beauty masks deliver high performance without inflated prices.
6. Designed by a consumer, not a corporation
This is not a trend product.
It was created by a woman who was looking for a great LED mask for herself.
The design, transparency, and performance come from experience, not marketing.

The Lerelle Beauty mask uses a matrix of LEDs that emit eight wavelengths. Each colour targets different concerns:
Should you choose a face mask or a full set
If you are just starting, the face mask is an ideal option.
If your neck and chest are important to you, you genuinely see the most balanced results with the Full Therapy Set.
Women who already own a face mask from another brand often upgrade with the Neck and Chest Mask to complete their routine.
How often should you use LED masks
Three to five sessions per week is perfect.
Each session can take ten to thirty minutes.
Consistency is more important than perfection.
