In a word, yes. I have stated in previous articles that companies who make photo-rejuvenation devices use "certain kinds of light" in their products. The color choices are not random nor are they used because they look good. There are actual reasons why you see the colors you see LED photo rejuvenation lights.

In another article I recently wrote I used photosynthesis in plants as an analogy to illustrate why photo-rejuvenation devices works. I’d like to carry the plant analogy a little further to address this question.

I find it fascinating that when it comes to the metabolism of plants and us that we often work opposite to plants and visa versa. Before I go any further I’d like to make sure we understand the word metabolism. The metabo part of the word means to change and ism is an action, so it is the action of changing. It is the ability plants and animals have to take inputs like food, air, water and LIGHT and change them into useful benefits such as; respiration, digestion, movement, CELL DIVISION, etc. Now let’s look at some of these opposites. Plants thrive in an acid environment; we do better when we are more alkaline. We thrive on oxygen and expel carbon dioxide; plants thrive on carbon dioxide and expel oxygen. Plants love ultra violet light and thrive when they get a lot of it, we on the other hand can tolerate it, but a lot of ultra violet light can be damaging to our cells. We seem to do very well with light that is opposite from purple and ultra violet namely red and infrared. By the way infrared is light that is not visible to us but is "seen" or detected by our cells and is very stimulating to them. That is precisely why you will see red, or colors close to red such as amber, and infrared in photo rejuvenation devices. It also explains why you shouldn’t see purple or ultra violet lights in them.

So, when you see your garden plants growing faster as summer approaches, think about how invigorating purple and ultra violet light is to plant cells, and realize, that the correct photo-rejuvenation device is as equally invigorating to our skin cells.
