Which type of light therapy is specifically used for treating acne?

Blue light therapy is specifically used for treating acne due to its ability to target and eliminate the bacteria responsible for causing acne breakouts. The blue light penetrates the skin and has a wavelength that is effective at destroying Propionibacterium acnes, the bacteria that contribute to the development of acne lesions. This method also helps to reduce inflammation and the overall severity of acne, making it a popular choice in dermatological treatments.

While red light therapy is beneficial for reducing inflammation and promoting healing, it is not as directly involved in the treatment of acne as blue light therapy. Green light therapy is often used for pigmentation issues, and yellow light therapy is associated with improving skin tone and reducing redness. Therefore, blue light therapy stands out as the specific choice for effectively addressing acne.
