1. Product features
1). Highly targeted: The specific wavelength of light emitted by the 308nm UVB phototherapy device can directly act on melanocytes deep in the skin, effectively promoting the production and distribution of melanin, thereby providing precise treatment for vitiligo.
2). Efficient and fast: Compared with traditional treatment methods, the 308nm UVB phototherapy device can observe the treatment effect in a shorter time, greatly shortening the treatment cycle and saving time for patients.
3). Safe and non-damaging: The treatment process of this phototherapy device is gentle, does not involve normal skin, avoids damage to surrounding tissues, and reduces side effects and discomfort during the treatment process.
4). Widely applicable: Regardless of age, gender, or severity of illness, the 308nm UVB phototherapy device can provide safe and effective treatment, especially for patients who are insensitive or ineffective to traditional treatment methods.
2. Treatment process
1). Preliminary diagnosis: First, the doctor will conduct a comprehensive skin examination on the patient to diagnose vitiligo and assess the severity and distribution of the condition.
2). Treatment preparation: Before treatment, the doctor will clean and disinfect the patient's skin to ensure that the skin in the treatment area is clean and free of infection.
3). Phototherapy treatment: According to the patient's specific condition, the doctor will set the appropriate light dose and irradiation time, and use a 308nm UVB phototherapy instrument to perform irradiation treatment on the patient. Each irradiation time is generally a few minutes, and treatments are performed 1-2 times a week.
4). Postoperative care: After the treatment, the doctor will inform the patient of precautions, such as avoiding direct sunlight, keeping the skin clean, etc., to ensure the treatment effect.
3. Treatment Instructions
Generally, it starts with 10 seconds for the first time (the initial time for children is halved), and the skin reaction is observed for redness the next day (usually changes occur around 6 to 8 hours). The time is very short, and there is basically no response.
1). If not, increase the next irradiation time by 10 seconds.
2). If there is redness, and it is still slightly red or almost invisible before the next exposure, maintain the exposure time every other day.
3). If there is redness, but it is very severe, stop irradiation and wait until the erythema disappears. The time will be reduced by 20%.
4). If there is no erythema, you can increase the time of irradiation every day, once a day; if erythema occurs, you can maintain this time and irradiate once every two days.
5). When taking the photo, cover the surrounding normal skin with a covering cloth to prevent the normal skin from being darkened.
6). Itching, peeling, and slight pain may occur after phototherapy, which is normal. A three-month course of treatment is suspended for two weeks.
7). In order to observe changes in the affected area, it is best to provide comparison of recent exposure pictures during phototherapy consultation.
3. Precautions
1). Individual differences: Different patients have different sensitivities to 308nm UVB light. The doctor will set the initial exposure dose based on the patient’s skin type and exposure experience, and adjust the dose according to the patient’s response in subsequent treatments.
2). Photoallergic reaction: A very small number of patients may have allergic reactions to 308nm UVB light. If symptoms such as erythema, papules, wheals, etc. appear, treatment should be stopped immediately and reported to the doctor.
3). Continuous treatment: Since the treatment of vitiligo takes a certain amount of time, patients should insist on treatment according to the doctor's requirements and follow up with follow-up appointments on time so that the doctor can adjust the treatment plan according to changes in the condition.
4). Sun protection: The skin after treatment is more sensitive and easily damaged by the sun, so patients should use sun protection to avoid direct sunlight.
4. Pay special attention to:
1).Safe storage: Please make sure to store the 308nm UVB phototherapy device out of the reach of children to avoid misuse or overexposure by children, which may cause skin damage.
2). Eye protection: When performing treatments around the eyes or that may be exposed to the eyes, be sure to wear special sunglasses or take other effective protective measures to prevent the light emitted by the phototherapy device from directly irradiating the eyes and causing eye damage. .
3) Read the instruction manual carefully: Before using the 308nm UVB phototherapy device, please be sure to carefully read and understand all operating instructions and precautions in the instruction manual. Do not blindly test or exceed recommended exposure doses, because even if no adverse effects are visible immediately, excessive exposure may cause serious damage to the skin the next day. Follow the recommendations on the instructions to ensure your treatment is both safe and effective.
