Treatment
How to use UV Phototherapy?
Step 1: please take a bath for 15 to 20 minutes to remove skin surface skin cells (scales) before treatment.
Step 2: patients need to determine the MED.
Note:
1.Intensity of the kernel uv lamps is 7 mW/cm2
2.MED calculation method: irradiation time S = dose (J/cm2) * 1000/7 (mW/cm2)
Step 3: Undergo the first treatment within safe distance between machine and skin lesion is typically 3cm
Step 4: Evaluate the first treatment effect, then adjust the time, and distance for each further treatment.
Treatment:
Psoriasis:3 ~ 4 times / week, (15 ~ 20 treatments) at 40+ seconds per treatment depending on patient response/need.
Vitiligo:2 ~ 3 times / week, (30-50 treatments) at 40+ seconds per treatment depending on patient response/need.
Parapsoriasis: PUVA, UVA/UVB, NB-UVB: 4 times / week, until improvement.
Dosage and time adjustment:
1. No erythema or Previous light erythema disappeared
|
Each usage increase 20~ 25% /dose.
|
2. Mild erythema effect
|
Same as the last dose or increase 10% dose, if erythema effect disappears, same as 1.
|
3. Asymptomatic, clear the shinning erythema
|
Stop treatment for one time, then with the same exposure, and/or with 10% increase dose.
|
4. Painful erythema, or with edema, blister
|
Stop treatment, until recovery. Reduce the dose by half, subsequently every time increased by 10% dose.
|
MED test method:
Step one: choose your skin type

For example: III type skin
You can see the initial dose is 0.3 J/cm²

The machine Intensity is 7 mW/cm²
MED calculation method for: irradiation time S = dose (J/cm2) * 1000/7 (mW/cm2)
Time=0.3J/cm²*1000/7mW/cm² =43 seconds
This mean: you need to irradiate 43 seconds at the first time, and so on.
Notice:
- Although the method that determines radiation dosage by skin type is simple, but not as accurate as MPD or MED.
- Specific drugs may increase the skin sensitivity to light, thereby to affect the determination of skin type.
- It is also important to learn about the patient’s reaction after long-term sun exposure to determine radiation dose.
If two patients are the same skin type, the slow to tan one should adopt a lower dose.
