Small Devices

Handheld Devices

These devices are easy to carry and can easily fit on the hand. The device is best for:

  • Facial treatments
  • Pain relief in different parts of the body
  • Spot treatment for different skin problems

Face Masks

These devices are designed mainly for facial treatment and can be equipped with adjustable settings to help treat different skin problems

They are also easily stored and used and may be comfortable to maintain facial skin whiteness and beauty.

Medium Devices


These medium-sized panels are best for treating the back, legs, or torso as they offer more coverage than handheld units. They may be placed on stands or any level surface. This device may be suitable for those who want to enjoy the RLT sessions more.

Pads and Belts

Pads may be wrapped around the waist, thighs, or arms, and belts may be used for the thighs. These flexible devices are targeted for more significant areas to be treated, and their coverage still differs from handheld devices.

Large Devices

Full-body Panels

These are large panels that are applied to a serious part of the body. Such panels are great for full-body wellness, and athletic recovery, as well as for more extensive skin treatments possible. They require a dedicated space to be placed but provide the most thorough and efficient treatment.

Beds And Capsules

They are like tanning beds and cover the whole body. These expensive units can be found in professional settings like spas and clinics. However, they are also available to consume at home. Using them recreationally can be an investment in a consistently higher quality of red light therapy.

What Size Red Light Therapy Should You Get? (Defining Major Factors)

Here are the factors that you need to consider before determining the RLT size

  1. Your Treatment Goals

The first thing to consider is the goal you’re planning to achieve with your RLT device. For instance, a small or medium RLT device would suit facial skin care, wrinkle reduction, and acne treatment. 

Whereas, a smaller RLT device with a higher irradiance is best for targeted pain relief in joints, muscles, or wounds.

Here are the sizes you should grab for certain needs:

  • Facial Skin Care: small to medium
  • Autoimmune Diseases: small to medium
  • Localized Pain Relief: medium
  • Wellness and Recovery: medium
  • Athletic Performance: medium to large
  • Full-Body Rejuvenation: large
  • Wounds and Inflammation: medium to large
  1. The Cost of Your RLT Device Size 

The cost of red light therapy devices varies a lot, as their price depends on Size, Quality, and Features.

  • Small handheld devices are usually less expensive and are a good pick for beginners and those with budgetary constraints
  • Medium-sized panels are comparatively more expensive than handheld ones and provide a great option for coverage and value
  • Full-body panels are the most expensive option and allow for the best coverage. 
  1. Portability

First, you need to determine whether you need your RLT devices to be portable. If portability is a requirement, then small handheld RLT devices would be the best option. 

However, medium-sized panels offer a balance of portability and coverage and are suitable for those who want to relax or take this therapy session. 

Full-body devices are less portable as they are relatively heavy and large, but some devices are designed with lightweight materials and is also foldable. 

  1. The Size of Your Space

You also need to consider the size of your space before you get an RLT device.

Small devices are portable and easy to store, so your space won’t be an issue here. On the other hand, medium-sized panels fit into most home environments without taking up much space. Full-body RLT devices require a designated area to be placed and used. 

How to Get the Most Out of Your Red Light Therapy Device?

  • Whether you have a small, medium, or large red light therapy device, you need to follow general procedures to get the most out of your treatment. 
  • Follow the established durations for the application you own. Second, consistently maintain the right distance between yourself and the device. 
  • Clean your skin before applying the red light: this will rid it of the dirt, oils, or makeup it routinely accumulates. 
  • Remember to protect your eyes. Always use the glasses that come with your red light therapy device. 
  • Don’t forget to follow the user instructions that you gained access to after buying the particular device.
