Safety of Home Phototherapy

Many people worry that ultraviolet (UV) radiation may cause skin cancer, but home 308nm phototherapy devices are fundamentally different from natural sunlight:

1、Pure Light Source

Natural sunlight contains harmful stray light such as infrared and gamma rays. Long-term exposure may indeed increase the risk of skin cancer. In contrast, home 308nm phototherapy devices use UV light at a specific wavelength (308nm). After careful selection, ineffective and harmful light is completely eliminated, retaining only the wavelength effective for treatment.

2、Controllable Dosage

The devices allow precise adjustment of irradiation intensity and duration, avoiding the uncontrollable nature of natural sunlight.

3、Clinical Validation

As a physical treatment method, 308nm UV phototherapy has been clinically used for nearly 30 years, with no clear reports of carcinogenic cases worldwide.

4、Strict Regulation

As Class II medical devices, safety indicators such as light intensity and radiation protection are strictly inspected by the National Medical Products Administration, ensuring the safety of compliant products.

Key Considerations for Home Phototherapy

Adverse reactions are often caused by improper operation (e.g., excessive dosage) rather than being common occurrences. Most of these reactions are temporary and resolve naturally with metabolism. To ensure safety, the following recommendations are advised:

1、Standardized Use

Use strictly under the guidance of a doctor or phototherapy specialist. Adjust the dosage and frequency according to personal skin sensitivity, and avoid blindly increasing irradiation intensity in pursuit of quick results.

2、Prompt Response to Abnormal Reactions

If abnormal reactions occur during phototherapy, promptly contact a professional or visit the dermatology department of a hospital. These issues can usually be properly addressed.
