What type of treatment involves applying rays to the skin for issues like acne and wrinkles?

Phototherapy refers to the use of specific wavelengths of light to treat various skin conditions, including acne and wrinkles. This treatment method utilizes ultraviolet, visible light, and infrared light to penetrate the skin and stimulate various biological processes. In the case of acne, phototherapy can reduce inflammation and kill bacteria associated with acne breakouts. For wrinkles, certain wavelengths can encourage collagen production and skin rejuvenation, leading to smoother skin and a reduction in the appearance of fine lines.

While other treatments like ultrasound therapy, laser treatment, and microneedling also address skin issues, they operate on different principles. Ultrasound therapy uses sound waves to penetrate the skin, laser treatment utilizes focused light beams to resurface the skin or target specific concerns, and microneedling involves creating tiny wounds to stimulate the body’s healing processes for skin rejuvenation. However, phototherapy specifically leverages light as the primary mechanism of treatment, making it the most accurate answer for this question.
