Promising clearer, smoother, and more youthful skin, LED masks have quickly become a favourite for many skincare enthusiasts. The appeal of an at-home treatment that promises professional-level results is undeniable. However, before clicking the buy button, it’s important to know how they work.

Glowing skin is always in, but it’s essential to make sure you’re using the right tool for the job. Let’s explore the science behind LED masks and some of the best LED masks available.

Let there be light: What is LED light therapy?

LED (light-emitting diode) therapy isn’t exactly new. It’s been used in clinical dermatology for decades. Before that, even NASA experimented with LED technology to promote tissue healing in space. The science behind it is surprisingly simple: different wavelengths of light penetrate the skin at varying depths. They trigger biological processes that can improve skin health over time.

In skincare, the most common LED wavelengths are, from higher to lower:

• Near-infrared light (up to 850 nm): Reaches deeper layers of skin, supporting healing and reducing inflammation.
• Red light (around 630–700 nm): Boosts collagen production, which helps soften fine lines and improve elasticity.
• Yellow/amber light (around 570–590 nm): Calms redness, reduces sensitivity, and promotes radiance.
• Green light (around 520–540 nm): Believed to help with pigmentation and even skin tone (although the clinical evidence is less robust compared to red and blue light).
• Blue light (around 415–470 nm): Targets acne-causing bacteria, making it a go-to for breakouts.

These devices typically use a combination of these lights to address a wide range of skin concerns. While the effects may vary depending on the device and individual skin types, LED masks have shown potential for delivering results when used consistently.

Professional clinics often use medical-grade devices with higher intensities and a wider range of settings. But recent innovations in consumer technology have brought pared-down versions into our homes.

Do LED masks actually work?

The short answer is yes. They can be effective, but only if you’re using the right mask and following the correct usage instructions.

In short: yes, but with important caveats. Clinical studies support the use of LED light therapy for various skin concerns, including acne and signs of aging. For example, this recent study found that at-home LED devices using red and/or blue light significantly reduced acne lesions. It showed a 45.3% reduction in inflammatory lesions and a 47.7% reduction in non-inflammatory lesions.

As for anti-ageing benefits, red LED light stimulates collagen production, which is crucial for maintaining skin elasticity and reducing wrinkles. Recent studies have found that red light therapy improves skin complexion, roughness, and collagen density, contributing to the reduction of fine lines and wrinkles.

However, you can only typically see these benefits with regular use over weeks or even months (it’s the small habits that matter!). LED masks aren’t quick fixes, and they aren’t substitutes for professional treatments like in-clinic lasers, either. Instead, they work best as long-term tools to enhance a broader skincare routine. Nothing beats SPF, hydration, and realistic expectations.

Are LED masks safe?

When used as directed, LED masks are generally safe for most people. However, it’s important to follow the manufacturer’s guidelines carefully to avoid irritation or overuse. Some people may experience mild redness or dryness after using an LED mask, particularly if they have sensitive skin, so starting with shorter sessions can help your skin adjust.

It’s also crucial to ensure that the device you’re using is from a reputable brand and has been cleared for safety. Look for certifications like CE marking, which indicates that the product meets European safety standards, or FDA approval for devices marketed in the United States.

For those with certain skin conditions, such as photosensitivity or lupus, it’s advisable to consult a dermatologist before starting LED light therapy, as some conditions may make the skin more sensitive to light.

What should you consider before buying a LED mask?

Shopping for an LED mask can feel overwhelming — the market is flooded with sleek-looking gadgets promising salon-worthy skin. So how do you separate high-performance devices from glorified mood lights? Here’s what to look for:

• Wavelengths and light types: Ensure the mask offers clinically relevant wavelengths (e.g. red and blue light in the correct ranges). If pigmentation or inflammation are your concerns, look for additional light options like green or amber.
• Fit and coverage: A good mask should sit close to the skin and cover all key areas. Flexible designs with adjustable straps tend to offer better comfort and consistent results.
• Safety features: Look for in-built eye protection or an auto shut-off mechanism. Don’t compromise on certified safety standards.
• Ease of use: You’re more likely to stick to regular sessions if the mask is intuitive, low-maintenance, and easy to clean.
• Brand reputation and reviews: Read real-world testimonials. Are people seeing measurable results? Is customer service responsive?
