Which color of LED light is known to reduce hyperpigmentation?

The color of LED light known to reduce hyperpigmentation is green. Green LED light therapy is effective because it targets melanin production in the skin. Melanin is the pigment responsible for skin color, and when produced in excess, it leads to hyperpigmentation, such as dark spots or uneven skin tone.

The mechanism of green light involves its ability to penetrate the skin at a specific wavelength that helps to lighten pigmentation and even out skin tone. Studies suggest that it can help diminish the appearance of discoloration and promote a more uniform complexion.

In contrast, blue light is primarily used for its antibacterial properties, making it effective for acne treatment rather than addressing pigmentation issues. Red light is known for its benefits in anti-aging and skin rejuvenation, stimulating collagen production and reducing inflammation, but it does not specifically target hyperpigmentation. Yellow light can enhance skin radiance and improve redness but is not primarily associated with reducing hyperpigmentation. Thus, green is the color of LED light specifically recognized for its role in reducing hyperpigmentation effectively.
