Is phototherapy effective for treating acne?

Generally, phototherapy is an effective non-pharmacological treatment for acne. Its core mechanism involves using the photobiological effects of intense pulsed light to improve the pathological mechanisms of acne, and it demonstrates significant efficacy for mild to moderate acne. A detailed analysis is as follows:

Phototherapy utilizes light energy of different wavelengths, such as blue light, red light, or violet light, to reduce inflammation caused by acne and to kill the bacteria responsible for triggering acne. Phototherapy for acne is a non-invasive treatment that has anti-inflammatory and antibacterial properties. It can also promote skin metabolism and accelerate the repair and healing of acne lesions, offering better therapeutic effects for mild and moderate acne.

Phototherapy can be tailored to individual patients according to the severity of their acne symptoms, making it a flexible and effective treatment option. However, for severe acne, it may be necessary to combine phototherapy with other treatment methods, such as oral or topical medications, to achieve better therapeutic outcomes.

Phototherapy is an effective treatment for acne. However, when considering this treatment option, it is recommended to consult with a dermatologist to determine the most suitable approach based on individual circumstances. Additionally, during and after treatment, it is essential to strictly follow the doctor's instructions and adhere to post-treatment care guidelines.
