Using light for therapeutic purposes is not a novel phenomenon—it dates back a few centuries. So before acquainting yourself with the benefits of using light therapy, particularly violet light therapy, there are two points that need some elucidation.
1. What Is Light Therapy?
In the 19th Century, Dr. Neil Swanson was able to demonstrate how short wavelengths of lights for skin penetration can heal the damaged cells or kill the bacteria in the skin. Initially, the results supported the healing of lupus vulgaris by using light to penetrate the skin. Later, more skin conditions were found to have positive results using light therapy.
Advancements in technology has increased the applications of light therapy and now other autoimmune skin problems like psoriasis, vitiligo, eczema and rosacea are treated using this with light therapy.
Just 40 years ago NASA discovered that red light could be used to stimulate growth of plants and healing of injuries that astronauts had in space. Later discoveries revealed that light therapy can also be used to slow down the process of aging skin cells. But how does light therapy is actually able to achieve all of this?
2. How Does Light Therapy Work?
If you are able to see the visible colors of light, it actually means that you are looking at different wavelengths of light. Different color lights has different wavelengths and greater the wavelength, the deeper would it get into the skin.
A red color light has a wavelength of 700 nanometers, while that of violet light is 400 nanometers. Therefore, red light would penetrate as deep as into subcutaneous layer and ignores the penetration benefits over the upper layers like Dermis and Epidermis. But when it comes to violet light, it targets your epidermis and dermis and aids in the treatment of acne more effectively.
So now let’s move onto the skincare benefits of violet light therapy.
Reducing the Acne Formations
One of the most annoying and terrible skincare problems is acne. Almost every person at some point in their life gets at least some sort of acne condition. There are many treatments that can help. Microdermabrasion, for example, can peel off your epidermis layer so new cells can form.
Estheticians can add extra precaution and a more soothing, lasting effect with violet light. Violet light can help to speed up this healing process and kill the bacteria that’s causing acne to appear. Violet light therapy soothes the skin and reduces the redness and skin irritation that results from microdermabrasion.
Reducing the Appearance of Fine Lines
How can light therapy assist with age spots? To understand aging we need to know the role of melanocytes.
Melanocytes are responsible for the formation of melanin, the substance that gives our skin color. To protect our skin from sun damage, the body produces melanin, which can also darken the skin and stops the penetration of the sun’s harmful UV rays. It is the body’s natural response to prevent mutation of any kind which can lead to the possibility of many skin conditions.
Brown spots from the formation of melanin are the natural consequences of this mechanism that ages the cells. Violet light therapy simply reactivates skin cells and redistributes melanin throughout the skin, preventing the appearance of fine lines associated with aging.
