For what purpose is yellow light primarily used in skin treatment?

1. Enhance skin firmness

2. Reduce swelling and inflammation

3. Increase pigmentation

4. Stimulate collagen production

The correct answer is: Reduce swelling and inflammation

Yellow light is primarily used in skin treatment for its ability to reduce swelling and inflammation. This is particularly beneficial for clients who may be experiencing redness or irritation in their skin, as yellow light therapy helps soothe and calm the skin. It works by promoting lymphatic flow, which aids in the removal of toxins and reduces fluid retention, ultimately leading to decreased puffiness and inflammation. While options like enhancing skin firmness or stimulating collagen production may involve other light therapies, yellow light is specifically recognized for its anti-inflammatory properties. Similarly, the treatment does not focus on increasing pigmentation; rather, it aims to create a more balanced and uniform appearance by addressing issues of redness and irritation. Understanding the specific uses of different light wavelengths can help estheticians tailor their treatments to the individual needs of their clients.
