In this guide, we'll walk you through the key things to know about red light therapy and choosing a well-made, effective device. We're excited for you to start enjoying the benefits of light therapy from the comfort of your home!

What is Red Light Therapy?

Red light therapy (RLT) is a non-invasive treatment that uses specific wavelengths of light to penetrate the skin and stimulate cellular function. By boosting ATP production (the energy currency of cells), red light therapy can be used to promote healing, treat physical ailments, reduce inflammation, target pain and soreness, enhance skin health, improve cognitive function, and improve your sleep.

Red and near-infrared light are the stars of the show. Red light is visible to the human eye, while near-infrared light is not visible to the human eye. Together, they penetrate your skin and energize the cells in your soft tissues, muscles, and even bones. It’s science, but it seems like magic and feels like self-care.

How Does Red Light Therapy Work?

It's All About Cells

At the core of red light therapy is your body’s foundation: the cell. Every tissue, muscle, and organ depend on how well your cells function. As we age, our cells lose their ability to perform at their full potential. This decline in cellular efficiency is what drives many age-related issues, from slower recovery to wrinkly skin.

Here’s the exciting part: researchers have discovered that by targeting and supporting cellular health, we can address the aging process in a revolutionary way. Red light therapy gets straight to the source, energizing your cells for better performance across your entire body.

The Mitochondria Effect

We all remember that the mitochondria are the "powerhouse of the cell" — a lesson we'll take from middle school to the grave. Mitochondria are in every cell and work by converting the food you eat into energy your cells can use. That energy is called adenosine triphosphate (ATP, for short).

Red light is absorbed by a molecule in the mitochondria called cytochrome C oxidase, helping it create ATP more efficiently. The result? More energy for your cells to work at their full potential.

Why It Matters

When your cells perform better, you perform better. From reducing inflammation to speeding up recovery and promoting skin rejuvenation, the benefits of red light therapy are nearly endless because we're promoting health at the source — the cell. With ongoing research into red and near-infrared light (and other light spectrums too), the potential applications of this groundbreaking technology continue to grow.

At Renew, we’re not just bringing you cutting-edge light therapy — we’re delivering a product to enhance every aspect of your life. Effortless healing, a sense of rejuvenation leading to elevated living, and the confidence to show up as your best self. That’s the power of light.

What are the benefits?

There are scientifically researched benefits that involve the use of red light therapy.

  • Skin health: Enhances skin health and complexion. Red and near-infrared light increase collagen production and synthesis, reduce hyperpigmentation and scarring, shrink pores, smooth wrinkles and fine lines, and reduce acne.
  • Pain management: Reduces inflammation and alleviates joint pain. Red and near-infrared light enhance blood circulation, stimulate cell growth and regeneration, and reduce the inflammation response.
  • Enhanced performance: Speeds up muscle recovery post-exercise. Red and near-infrared light improve blood flow, promote lactic acid metabolism, enhance muscle responsiveness, and reduce risk of muscle damage.
  • Fat loss and cellulite reduction: Stimulates fat metabolism and aids in weight management. Red and near-infrared light stimulate muscle cell metabolism, activate enzymes and metabolites in the body, and increase metabolic rate.
  • Improved sleep: Promotes relaxation. Red and near-infrared light are thought to promote secretion of melatonin by the pineal gland (regulates the biological clock), improve sleep quality, and alleviate sleep disorders.
  • And more: With ongoing research into red and near-infrared light (and other light spectrums too), the potential applications of this groundbreaking technology continue to grow.

What Are The Key Questions to Ask When Buying a Device?

Making an investment in your wellness means doing your homework, but don’t worry — we’ve got your back. With so many options on the market, it’s important to know what truly matters when selecting a device that aligns with your goals. Here are the questions you should ask to make a confident, informed decision:

  • What wavelengths do the device offer? What is the device's irradiance? (We’ll explain why this matters below.)
  • What type of LEDs are used in the device, and what is their wattage? (We’ll explain why this matters below.)
  • What size device matches my goals? Are you looking for wide-range coverage, targeted treatments, or a face-focused solution?
  • Is the device backed by safety and quality certifications? This ensures you’re getting a product that’s built to perform safely and effectively.
  • Does the company offer customer support and warranty? A solid warranty and helpful support team mean peace of mind.

By answering these questions, you’ll begin to narrow down the choices and find a device that works for you. Keep reading for a closer look at why these factors matter.

The Crucial Components to Consider: Wavelengths, LEDs, and Irradiance (Power Output)

When it comes to choosing a red light therapy device, not all are created equal. The quality and effectiveness of a device hinge on a few key technical components. Let’s break these down so you can make an informed decision that delivers results.

Wavelengths: The Foundation of Effective Therapy

Wavelengths determine how deeply light penetrates your body and what benefits it provides.

  • Red Light (wavelengths 620nm- 750nm): targets the surface of the skin, promoting collagen production, reducing redness, and improving skin tone and texture.
  • Near-Infrared Light (wavelengths 800nm - 2500nm): penetrates deeper into muscles, joints, and tissues, making it ideal for recovery, pain relief, and overall cellular rejuvenation.

Why it matters: Devices with multiple wavelengths, like Renew’s, offer versatility and a broader range of benefits. Cheaper devices may lack near-infrared capabilities or use a single wavelength, limiting their effectiveness.

Renew's device Wavelengths are:

The Panels: Red: 610nm, 630nm, 660nm. Near-infrared: 810nm, 830nm, 850nm

The Mask: 415nm (blue), 605nm (orange), 635nm (red), 850nm (near-infrared)

LEDs: Quality Over Quantity
Light-emitting diodes (LEDs) are the workhorses of any red light therapy device.

  • High-Quality LEDs: Emit consistent, therapeutic wavelengths and ensure even light distribution for optimal results.
  • Low-Quality LEDs: Can degrade quickly, emit weak or inconsistent wavelengths, and fail to provide effective therapy.

Why it matters: Some less expensive devices use low-cost LEDs to cut corners. These LEDs may not deliver the power or consistency you need, meaning less effective treatments and shorter device lifespans. Renew's Panel LEDs are powerful 5 watt 3535 LEDs with ceramic substrate. Renew's Mask LEDs are 0.2 watt High-Density 4-chip LEDs and provide effective, powerful light output. This is just a fancy way of saying our LEDs deliver greater power than traditional LEDs.

Irradiance: The Power Behind the Light

Irradiance is a measure of how much light energy is delivered to your skin, typically expressed in milliwatts per square centimeter (mW/cm²). If the panel you're purchasing doesn't define or showcase the irradiance, it's likely a low power device.

  • Higher Irradiance: Ensures the light is powerful enough to penetrate deeply enough to reach your cells and provide therapeutic benefits.
  • Lower Irradiance: Results in weaker energy delivery, which can significantly reduce the effectiveness of your treatments.

Why it matters: Budget-friendly devices often advertise high power but deliver low irradiance, meaning you may not see the results you’re looking for. Renew’s devices are engineered to provide optimal irradiance for effective, time-efficient therapy. Renew's Panel Irradiance:

The Large Panel (measured using a Spectrometer):

  • 150mW/cm² at 3 inches
  • 126mW/cm² at 6 inches
  • 108mW/cm² at 12 inches

The Small Panel (measured using a Spectrometer):

  • 125 mW/cm² at 3 inches
  • 98 mW/cm² at 6 inches
  • 86mW/cm² at 12 inches

While high power output might mean a higher price tag, it’s worth the investment for faster, more effective treatments. Cheaper devices may advertise affordability but come with diminished performance and require longer treatments.

Why Are Some Devices Less Expensive?

It's likely you’ve noticed a wide range of prices in the red light therapy market, it’s not just about features — materials and build quality play a significant role as well. Here’s what to look for and why it matters:

  • Cutting Corners on LEDs: Lower-cost devices often use inferior LEDs with shorter lifespans and inconsistent wavelength delivery.
  • Reduced Irradiance: These devices may promise results but lack the power to deliver them.
  • Minimal Certification or Testing: Budget options might skip the rigorous quality control processes that ensure safety and efficacy.
  • Cheaper Materials for Housing and Components: Many lower-priced devices are made with low-quality plastic or subpar components. While this reduces manufacturing costs, it also affects durability, efficiency, and the overall lifespan of the device.

At Renew, we take pride in every detail:

  • Renew's Premium Aluminum Housing on the panels is beautiful and effective. Unlike bulky plastic or iron alternatives, our devices feature sleek, durable aluminum casings that ensured efficient heat dissipation and long-lasting performance.
  • Renew's Mask Premium Food-Grade Silicone offers flexibility and comfort during use.
