Ultraviolet phototherapy and visible light therapy offer different treatments, with one considered to be more invasive on the skin than the other. We’re here to help you understand the different levels of light therapy and how each level might be helpful towards any skin concerns you have.
Many people might not trust the healing powers of “light therapy,” simply from the fear of ultraviolet radiation. Those who are exposed to the sun and perhaps even a tanning bed have exposed their skin to ultraviolet radiation, which means there’s potential skin cell damage that’s already sustained.

What is Ultraviolet Radiation?
Let’s start with your understanding of ultraviolet radiation. In a simple sense, ultraviolet radiation is energy from the sun. How much of this energy is directed right at you can vary, but also be harmful.
- UVA – can cause wrinkles (type you can also get from tanning beds)
- UVB – can cause sunburns
- UVC – the most dangerous but don’t get through the atmosphere
Good Sun vs Bad Sun
So how do you know when you’re getting any “good sun” that’s actually going to help your skin get the natural Vitamin D it needs? In a previous post, we explained that the altitude of the sun must be at least 50° and above. Anything below that can be potentially damaging to your skin.
What is Ultraviolet Phototherapy?
First of all, phototherapy is just another word for light therapy. Here, we will explain how ultraviolet can be used to treat certain conditions, like psoriasis, vitiligo, and other autoimmune conditions.
The treatments all depend on the amount of wavelengths produced. The following is a diagram of the different wavelengths of light.
An autoimmune condition, called psoriasis, is usually treated with UVA and UVB. For example, Theralight’s DuaLight® machine directly targets the affected area and slows down the infection that’s creating the plaque.
- Atopic dermatitis
- and more (ask your medical professional for advice)
What is Visible Light Therapy?
Visible light therapy is what you might find in an Esthetician’s spa or even a medical spa. The systems produce wavelengths that range from 400 to 700 nm. So far, no dangers or risks have ever been found from using visible light therapy for treatments.
The wavelengths of 400 to 700 nm do not generally produce ultraviolet radiation. However, if you want to be absolutely certain, you might want to consider making sure your Esthetician has the mobile, hands-free, VersaClear® light therapy system that uses carbon filters to keep any form of toxins, chemicals, and even radiation from penetrating it.
Visible light can be used for any of the following:
- Brown spots
- and more
Estheticians who understand the power of light therapy generally use them in combination with their treatments.
