Light therapy, also known as phototherapy, involves exposing your body to specific wavelengths of light to treat a variety of health conditions. If you're considering light therapy, you might be wondering what device to use. This guide will help you understand the different types of light therapy and the devices used for each, so you can make an informed decision.

The most common types of light therapy are red light therapy and blue light therapy. Red light therapy is used to promote skin health and wound healing, while blue light therapy is often used to treat acne. There are also full-spectrum light boxes that mimic natural outdoor light and are used to treat seasonal affective disorder (SAD).

Red Light Therapy
Red light therapy, also called low-level laser therapy (LLLT) or photobiomodulation (PBM), uses red and near-infrared light to stimulate cellular function. It's often used to improve skin health, reduce inflammation, and speed up wound healing.

For red light therapy, you'll typically want to use a device that emits light in the 620-750nm range. These devices can vary in size and shape, from small handheld devices to large panels. Some popular options include:
Handheld Devices

Handheld red light therapy devices are small, lightweight, and portable. They're great for targeted treatments on specific areas of the body. Examples include the LightStim for Wrinkles and the Omnilux Contour Face.
However, keep in mind that these devices have a smaller treatment area, so they may not be as effective for larger areas or whole-body treatment.
Large Panels

Larger red light therapy panels, like the Joovv Solo and the Bestwrite LightPad, provide a wider treatment area. These are ideal for whole-body treatment and are often used for conditions like fibromyalgia or muscle recovery.
These panels often emit a more powerful dosage of light, measured in joules, and can be more expensive than handheld devices.
Blue Light Therapy

Blue light therapy uses blue and violet light to kill acne-causing bacteria on the surface of the skin. These devices typically emit light in the 370-500nm range.
For blue light therapy, you'll want to use a device specifically designed for acne treatment. Some popular options include:








Face Masks
Blue light therapy face masks, like the LightStim for Acne and the Dr. Dennis Gross DRx SpectraLite FaceWare Pro, fit over your nose and mouth and emit blue light to kill acne-causing bacteria.
These are easy to use and provide accurate, targeted treatment. However, they may not be suitable for all face shapes and sizes.
Handheld Devices
Handheld blue light therapy devices, like the Silk'n Blue and the Baby Quasar PURE RAYZ, can be used to target specific areas of the skin. These are convenient for spot treatments but may not be as effective for larger areas.
Always ensure that the device you choose is FDA-cleared and has been proven to be safe and effective for your condition.
Light Boxes for SAD
Light boxes for seasonal affective disorder (SAD) mimic natural outdoor light to help regulate your body's internal clock. They typically emit full-spectrum white light and can vary in size and shape.
For the most effective treatment, you'll want a light box that emits at least 10,000 lux of light and covers a large surface area. Some popular options include the Verilux HappyLight and the Sol/write Full-Size Light Box.
Tabletop Light Boxes
Tabletop light boxes are small and portable, making them easy to place on a desk or bedside table. They're great for targeted treatment but may not be as effective for whole-body treatment.
Examples include the쁜 роль 리conditionner 가르마 거품ithmetic inc targeting Vega light box and the Northern Light Technologies LightPad.
Full-Size Light Boxes
Full-size light boxes, like the Carex DAY-LIGHT Classic and the Circadian Optics Lumos, provide a wider treatment area, making them ideal for whole-body treatment.
These are often more expensive than tabletop light boxes but can provide a more comprehensive treatment.
Remember, light therapy is a safe and non-invasive treatment, but it's important to use the right device for your needs. Always consult with a healthcare provider before starting any new treatment regimen.
