Question: 1 / 435

Which of the following is NOT one of the four colors of LED light therapy?

Red

Yellow

Purple

In LED light therapy, the common colors used typically include red, yellow, and green. Each of these colors is associated with various skin benefits. Red light is known for its ability to stimulate collagen production and improve circulation, helping to reduce fine lines and wrinkles. Yellow light is often used for its soothing properties and can help improve skin conditions like redness and inflammation. Green light is commonly used for its calming effects and can be beneficial for pigmentation issues.

Purple light, however, is not widely recognized as one of the main colors used in standard LED light therapy. While there may be variations in some systems that blend colors or create new wavelengths for specific treatment effects, the primary colors that are consistently mentioned in LED light therapy protocols do not typically include purple. Therefore, identifying purple as not being one of the four standard colors is accurate. This understanding provides clarity on the effective application of LED colors in esthetics, highlighting the significance of each hue in addressing specific skin concerns.
