Cons of Red Light Therapy

Joovv red light therapy deviceThe best thing about the disadvantages of Red Light Therapy is that there are hardly any.

More specifically, the disadvantages of LLLT are not the disadvantages of the therapy itself but some technical problems that go with it.

Unclear Standardization

One disadvantage of red light therapy devices is that there is not yet sufficient standardization in the field of which wavelength and colors produce optimal results.

Joovv is a science-driven company that relies on clinical research. Clinical evidence shows that red and near-infrared wavelengths are most effective for human health.

Unfortunately, many cheap LLLT companies use unproven wavelengths and do not test or certify their products for human use.

That’s why Joovv is passionate about research, and there is no compromise regarding quality – their products are tested to get the best results and peace of mind.

Lack of Transparency and Fairness

Unfortunately, many light therapy companies do not believe in transparency and honesty.

Too many brands acquire designed lamps for plant growth and put their logos on them.

You’ll notice that many of these devices look the same external device branding.

Joovv has invested in its tools and engineering and has partnered with one of the world’s leading manufacturers. When looking for a health product, you shouldn’t accept anything but the best.

Make sure you get world-class quality and engineering with your red light therapy device.

Photosensitivity Concerns for Some People

People with photosensitivity problems should consult a trusted physician before using a therapy lamp.

Additionally, it would be best to ask your doctor about interactions between light therapy and your medications. That may decrease your risk of photosensitization.

Possible High Cost

Photodynamic Therapy costs from $ 25 to $ 200 per session. The prices depend on the place of service and the type of treatment.

Remember that treatments are needed approximately every three weeks and can last for months.

Red Light Therapy devices range from $ 149 to $ 1,000,000.

Currently, red light treatment is not covered by most insurance policies. However, some dermatologists may offer such a service. Your insurance plan may include guidance on cost factors and the benefits available.


Low-Level Laser Therapy is generally safe and can be a fruitful treatment option for those who want to maintain healthy skin and reduce inflammation.

Other uses of Light Therapy have promising early evidence.

Photodynamic Therapy is only part of a complete treatment for your health condition. You may require several treatments to start noticing significant changes.

If unsure, you should talk to your doctor to discuss potential benefits.
