As a Class II medical device for treating skin conditions like vitiligo and psoriasis, home 308 phototherapy devices have gained popularity among many patients due to their convenience. However, concerns often arise: Does it have side effects? Is long-term use safe? Below, Xiao Zan provides a detailed explanation on these matters.

As a Class II medical device for treating skin conditions like vitiligo and psoriasis, home 308 phototherapy devices have gained popularity among many patients due to their convenience. However, concerns often arise: Does it have side effects? Is long-term use safe? Below, Xiao Zan provides a detailed explanation on these matters.

Many worry that ultraviolet radiation may induce skin cancer, but home 308 phototherapy devices differ fundamentally from natural sunlight:

1.Pure Light Source

Natural sunlight contains harmful stray light such as infrared and gamma rays, and prolonged exposure may indeed increase the risk of skin cancer. In contrast, home 308 phototherapy devices use ultraviolet light at a specific wavelength (308nm). Through careful selection, ineffective and harmful rays are completely eliminated, retaining only the wavelengths beneficial for treatment.

2.Controllable Dosage

The device allows precise adjustment of irradiation intensity and duration, avoiding the uncontrollable nature of natural light.

3.Clinical Validation

As a physical therapy method, 308 ultraviolet phototherapy has been clinically applied for nearly 30 years, with no confirmed cases of carcinogenicity reported globally.

4.Strict Regulation

As a Class II medical device, its safety indicators, such as light intensity and radiation protection, undergo rigorous testing by the National Medical Products Administration. Compliant products are guaranteed to be safe.
