Is LED Worth the Hype? Here's What You Need to Know Before You Buy (With My Top Pick for LED Therapy)
I get asked about LED devices about 10 times a week, people want to know whether certain devices are worth the investment and whether they really work. Here’s the truth: while LED therapy is an amazing treatment, most devices out there are not worth your time or money. You need to look deeper than flashy marketing claims like "7 colours of light" or "perfect for all skin types." To help you avoid wasting your money, here’s what you actually need to look for:
What You Need to Know About LED Wavelengths:
It’s not about how many colours the light has, it’s about the wavelength (measured in nm). The clinically proven wavelengths are:
-
415 nm (Blue Light): Best for acne, targets acne-causing bacteria.
-
633 nm (Red Light): Stimulates collagen, reduces wrinkles, and rejuvenates the skin.
-
830 nm (Near-Infrared Light): Penetrates deeply for inflammation reduction, healing, and regeneration of cells.
When a brand lists colours like red, yellow, green, purple, etc., but doesn’t provide the exact wavelength in nanometers, you need to steer clear. It may not even be LED, but coloured lights! Without the right wavelength, the light just won’t penetrate your skin effectively.
Pro Tip: Look at the specifications or science section on the brand's website. If they don’t list the exact wavelengths ( the numbers), it’s a red flag.
Power (Joules/cm²) – This Is Where It Gets Critical!
-
30 J/cm²: This is your baseline power, and it’s still fantastic for home use. It gives solid, visible results with consistent use.
-
50 J/cm²: A more powerful option that delivers faster results, while still being safe for home use.
-
higher that 60 J/cm² : At-home devices should stay below this. Going higher may lead to irritation, especially for sensitive skin or melasma-prone skin.

Check the Science:
Look for clinical studies, published results, or any proven backing for the LED technology used. Devices with solid clinical data will show exactly how their light therapy works and why it’s effective for your skin. If it’s all about 7 colours but no data—move on.
Checklist for the Right At-Home LED Device:
Wavelengths (nm):
✅ 415 nm (Blue Light): Best for acne treatment.
✅ 633 nm (Red Light): Collagen stimulation, anti-aging.
✅ 830 nm (Near-Infrared Light): Deep tissue healing, regeneration.
Power (Joules/cm²):
✅ 30 J/cm²: Baseline power, perfect for regular use.
✅ 50 J/cm²: More powerful, delivers faster results.
❌ higher than 60 J/cm² : Too intense for sensitive skin at home.
FDA or TGA Approval:
✅ Check if the device is FDA or TGA approved to ensure it’s both safe and effective.
Coverage Area:
✅ Make sure the device covers a large enough area of your skin for effective treatment.
Device Design:
✅ Is the device comfortable for regular use? Does it fit your face/body properly for even coverage?
Brand Reputation & Reviews:
✅ Look for reputable brands with positive customer reviews and solid clinical backing.
Frequency of Use:
✅ Choose a device that’s designed for daily or regular use to get the best results.
Why Salon-Grade Devices Are Different:
Salon devices typically use higher-powered LED technology, which allows for faster results. However, the benefit of at-home devices is you can use them more regularly without the need to schedule an appointment, so consistency is key. You can still get amazing results at home, as long as you choose the right device with the correct wavelengths and power!
LED therapy is backed by science, and when used correctly, it can have amazing benefits for your skin. Just make sure you're choosing a device that delivers the right wavelengths and power!
I hope this gives you peace of mind when looking for at-home LED devices. If you're unsure about your device, feel free to ask me questions. I’ve spent years researching LED, and I’ve used it in my own salon for a long time. Don’t settle for gimmicks, get the right tech, and your skin will thank you!
