This post is all about LED light therapy, what they do, how they work, and some of the best LED devices at home for an LED light skincare routine.

But with so many devices on the market, it’s hard to know which ones are actually effective. In this post, we’ll break down:

• What each LED light therapy color does
• The key differences between red, near-infrared, and far-infrared light
• The pros and cons of LED light skincare masks vs. panels
• LED light therapy side effects to know
• What to look for when shopping (hint: wavelengths matter!)
• And of course, top picks for the best devices in the 660–850 nm range

Let’s get glowing!

What Does Red Light Therapy Do?

Every living cell needs good light to be healthy. -a.k.a Photosynthesis!- One of the most studied and popular wavelengths in LED skincare is red light, specifically at 660 nm. This wavelength penetrates the skin just deep enough to stimulate collagen and elastin production, helping to firm the skin and smooth fine lines.

So when people ask “what does red light therapy do?”, the short answer is:

• Boosts collagen for firmer, younger-looking skin
• Improves blood flow for a healthy glow
• Reduces inflammation and redness
• Speeds up healing (great post-facial or after extractions)

Near-Infrared (850 nm): Going Deeper for Healing

Near-infrared (NIR) light typically falls between 800–850 nm and penetrates even deeper than red light—down to the subcutaneous tissue. It supports:

• Cellular repair and ATP production (cellular energy)
• Deep tissue healing and circulation
• Reduction of chronic inflammation

For those seeking LED light therapy for skin benefits below the surface—like wound repair, deeper tissue inflammation, or even jaw tension—devices that combine 660 nm red light and 850 nm NIR light offer the best of both worlds.

LED Light Therapy Color Benefits: A Quick Overview

Color	Wavelength (Approx.)	Benefits
Red	620–700 nm	Anti-aging, healing, collagen production
Near-Infrared	800–850 nm	Deep tissue repair, inflammation reduction
Blue	405–470 nm	Kills acne-causing bacteria
Green	525–550 nm	Reduces pigmentation, calms the skin
Yellow/Amber	570–590 nm	Reduces redness and irritation

For this post, we’re focused on the 660–850 nm range—ideal for anti-aging and healing.

LED Light Therapy at Home: Face Mask vs. Panel—Which Is Better?

When choosing LED light therapy at home, most people end up deciding between two styles: face masks and panels. Here’s what you need to know.

Face Mask Type

Pros:

• Hands-free and easy to use
• Direct contact with the skin
• Often comes with multiple light colors (red, blue, yellow)

Cons:

• Only covers the face
• Limited power output (lower irradiance)
• May not offer near-infrared light

Panel Type

Pros:

• Higher power (faster, more effective sessions)
• Covers more area (face, neck, chest)

Cons:

• Requires sitting or positioning yourself in front of the device
• Can be bulkier or less portable

What to Look for in an LED Light Skincare Device (660–850 nm)

When choosing a device, you want to focus on,

Comfort and fit: Especially important for masks

Wavelength specification: Look for devices that clearly list 660 nm for red light and 850 nm for NIR.

FDA clearance or third-party testing (for safety and effectiveness)

Why LED Light Therapy Devices Aren’t “FDA Approved”

You might see claims like “FDA-approved LED light therapy device” floating around online or in product descriptions—but that’s not accurate. Here’s why:

The FDA does not approve most over-the-counter LED light therapy devices.

Instead, it can “clear” them for specific uses, usually under what’s called a 510(k) clearance. This means the device is considered substantially equivalent to another legally marketed device and is safe and effective for the same intended use.

Only certain prescription-level medical devices, like implants or pacemakers, go through the rigorous “FDA approval” process. Cosmetic and wellness devices like LED masks or panels only need to be FDA cleared, not approved.

Are There Any LED Light Therapy Side Effects?

Generally, LED light therapy side effects are minimal. It’s a non-invasive, painless treatment. But a few things to keep in mind:

• Eye safety: If your eyes are sensitive to bright light, always protect your eyes or wear goggles, especially with panels
• Photosensitivity: If you’re taking medications like Accutane or antibiotics, check with your doctor first

Wrapping Up: Making the Right Choice for Your Skin

Whether you’re just starting your LED light skincare routine or you’re ready to upgrade to a more powerful setup, choosing the right device can be transformative. Stick with wavelengths in the 660–850 nm range to get real results—whether that’s collagen stimulation, smoother texture, or accelerated healing.
