The therapeutic wavelengths and their penetration depths


Different lights of color will penetrate the skin to different depths. As you can see from the chart above, near-infrared light penetrates the deepest into the skin and blue light penetrates the skin to the smallest depth. Therefore, the color you need is most dependent on the condition or problem that you are trying to treat. Since acne appears on the surface of the skin, blue light works well to treat this. Red light is also often used to treat acne as that light penetrates deeper into the skins surface allowing it to fight against the acne that appears deeper. Since near-infrared light penetrates the deepest into the skin, it is often used to give an accelerated boost in treatment.


Combining colors


Some treatments will utilize multiple different colors together. This is a beneficial technique and can work to accelerate the healing process. Blue and red is sometimes combined to make purple and is very effective for acne. Blue and green can also be combined to get cyan and this is also helpful for acne and pigment stains.


Most handheld devices for LED light therapy will be pre-made to combine certain colors. You don’t need to buy multiple light devices for each color. Instead, you should find one that offers a few of the colors that you are interested in. You should also see if any of the devices utilize color combinations like blue and red and blue and green.


How can I make sure light therapy is a good option for me?


Before buying a handheld device, you should consult a dermatologist or esthetician. They will be able to tell you what products are the most trustworthy. They also can figure out what colors would work best for what you need treated and give you an accurate diagnosis on your skin issue. Because certain colors work to treat certain conditions, it is important to have an accurate idea of exactly what you need to be treated.
