What To Look For In An LED Face Mask

The beauty industry is buzzing about LED masks—and for good reason. Research continues to show us they can reduce the appearance of fine lines, creases, breakouts and even out skin tone and texture.

They can deliver remarkable results without needles, lasers, or downtime. Best of all, sleek, at-home designs make it easier than ever to enjoy professional-grade therapy on your own schedule.

But here’s the problem: not all LED masks are created equal. To see real, lasting improvements, you need a high-quality device designed to suit your specific skin problems.

The right choice can transform your skin. Below, we break down exactly what to look for—so you can invest with confidence and see the results you deserve.

Wavelength

First let’s break down the wavelength. Wavelength refers to the specific measurement of the light wave emitted by the LED. It determines how deep the light penetrates into your skin and what effects it has.

Each wavelength is measured in nanometers (nm), and different wavelengths correspond to different colors. The most common wavelengths used in LED face masks are Blue Light (400-500nm), Yellow Light (570-600nm), Red Light (620-750nm) and Near-Infrared Light (800-1200nm).

Each of these wavelengths has its unique way of interacting with your skin. While some have proved to be beneficial, others can actually harm the skin. We would recommend steering clear of brands that do not disclose the specific wavelengths used.

To experience results, choosing an LED mask with clinically studied wavelengths is essential. From over 30 years of research, the light wavelengths that have been proven to support and benefit your skin include:

Red Light

Research has shown that Red Light is effective for skin rejuvenation, aimed at reducing the appearance of fine lines and creases and improving skin texture and tone.

Near-Infrared Light

Invisible to the human eye, Near-Infrared Light penetrates deepest into the skin. By reaching deeper into the skin, it has been proven to promote recovery and support the body's natural renewal process.

The BON CHARGE Red Light Face Mask features the most studied wavelengths of Red (630nm) and Near Infrared Light (850nm).

Irradiance (Power Density)

Irradiance is the measurement of how strong or intense the light beam is. It is measured in milliwatts per square centimetre (mW/cm²). Each wavelength needs sufficient power density to reach below the skin's surface and do its job, whether promoting recovery or reducing fine lines.

Red Light Therapy is a low energy, non-thermal therapy - meaning it shouldn’t generate excessive heat. However, for LED masks to deliver real results, they need enough power for the skin cells to absorb the light effectively.

A higher irradiance often means a shorter treatment time, but more isn’t always better. If the irradiance is too high, this energy can convert into heat, causing the mask to become too warm. This can disrupt the session or even lead to undesired effects. On the other hand, if the irradiance is too low, the light won’t be powerful enough to deliver any real benefits.

So what is the optimal irradiance?

Research suggests that 35-50 mW/cm² provides the strongest evidence of LED therapy working as intended—making this range the ideal benchmark.

The BON CHARGE Red Light Face Mask features an Irradiance of 40.8mw/cm².

Number of LEDS

The number of LEDs is important to ensure complete and even coverage of the area being exposed.

When the LEDs are positioned with too much space between them, some areas may receive less light and may compromise the results.

Some masks have as few as 32 LEDs—far too little for full coverage. The BON CHARGE Red Light Face Mask stands out with 242 LEDs, delivering more light, more coverage, and better results.

Safe Materials

To protect and effectively expose your skin to LED therapy, it's essential to choose a mask that’s made from high-quality, safe and durable materials.

Some face masks have a hard plastic shell. The issue with this is, it can increase the exposure of your skin to microplastics (small pieces of plastic).

Even though these microplastics don’t usually get very deep into your skin, the chemicals in plastics can still be absorbed. This could cause irritation or harm the skin.

With this in mind, we recommend choosing a mask that's constructed using medical-grade silicone. The BON CHARGE Red Light Face Mask is made from A-grade medical silicone that won’t stick to the skin, preventing any pulling, dragging, or irritation.

Medical-grade silicone is known for being non-toxic, durable and extremely versatile. It's also ultra hygienic, hypoallergenic and widely trusted as a safe option for your skin.

Comfortable Design

While technical specifications are crucial, comfort and design are equally as important. Some devices are made from soft flexible silicone while others use rigid plastic.

We recommend choosing an LED mask, constructed from flexible material, rather than a hard-shelled mask. A flexible mask will mold to the contours of your face, allowing it to absorb more of the light and provide more even coverage.

Hard-shell masks aren’t as flexible and may leave some areas untreated, leading to uneven results.

Not to mention a flexible, flat design is easier to pack and take with you, so you never have to skip or sacrifice a red light session.

The BON CHARGE Red Light Face Mask and Red Light Neck And Chest Mask are made from a flexible silicone allowing the LEDs to sit directly on the skin. The masks deliver a high concentration of light, providing even results.

For additional comfort, the BON CHARGE Red Light Face Mask also comes with cushioned protective eye inserts, keeping the mask in place while blocking out excess light. This allows you to move around freely and go about your daily tasks —like doing the dishes, reading, or working on your computer.

Conclusion

Your skin deserves only the best, but not all LED light therapy devices live up to that standard. Given that an LED mask is a significant investment, it’s important to thoroughly research your options.

Now you know what to look for, you can explore the LED masks on the market with confidence.

Although LED masks are still much more affordable than in-office light therapy, some medical-grade options can be expensive. However, to properly protect and care for your skin, a high-quality mask is worth the cost.

Make sure your choice is effective, safe, and aligned with your skincare goals.
