Red light therapy is a 100% natural remedy with zero side effects. It has been proven to be an effective solution for a wide range of healing and rejuvenation.

What Conditions Are Treated With Red Light Therapy?

Because this therapy can help accelerate the skin's ability to heal, it can be used to address a variety of conditions including the following.

 Acne And Swollen Acne Marks



Minor Burns

Cuts, Scrapes And Wound Care

Dry Skin And Psoriasis

Scars And Stretch Marks

Sun Damage


How The Therapy Works

Red light permeates the skin to a depth of approximately 8 to 10 mm. After it's been absorbed, the light energy is transformed into cellular energy, that energizes the body's natural processes and ignites a series of metabolic events.

All of these steps work together to provide benefits in the areas of anti-aging, healing of wounds and injuries, and the relief of pain. But regardless of what application is used, red and infrared light therapy share the same general benefits.

Light Therapy For Your Skin

The most common use for red light therapy is anti-aging of the skin, but it is also used to treat an expanding list of skin conditions including:

Red LED Light Therapy

Red LED light therapy is very popular today, especially for anti-aging, and the treatment of acne and rosacea treatment. So why is it so popular? Red LED light therapy is red light therapy, that uses an LED light source instead of incandescent, fluorescent, or laser. However, red LED light therapy does have some unique benefits of its own.

NASA chose to use red light therapy when it brought the procedure into space sometime around the year 2000. They selected this technology for its low-energy requirements, and its low heat emission and low weight.

Those very same assets made future research more precise, and hundreds of studies from around the world have revealed the benefits of red light therapy.

Why Red LED Light Therapy Is Superior To Other Types

It Has A Shorter, Closer Wavelength Span

Red LED light has a shorter and closer wavelength span than other types of bulbs. Because of this, some consider LEDs a superior means for delivering the needed light for a given application.

No Heat Required

With red LED light therapy, there is very little heat generated, which makes the technique safer and much more pleasant.

Durable And Longer Lasting

Today's LED devices utilize electronics and metal (or plastic) housing, which is much sturdier and longer lasting than incandescent or fluorescent bulbs that are constructed of glass.

Portable And Compact

LEDs are small, so it's easy to use them in a small, hand-held, portable device.

Friendly To The Earth

This therapy is more eco-friendly because they produce the same amount of light while using a small fraction of the energy.
