How Does 311nm UVB Work to Vitiligo

311 narrow-band UVB ultraviolet rays irradiate the skin lesions, stimulate the skin to produce photochemical reactions or regulate immune responses to stimulate the body’s immune regulation ability, promote melanocyte regeneration to achieve the purpose of treating vitiligo. It has good safety and tolerance, and avoids the risk of skin burns and cancer caused by traditional phototherapy.

1. Stimulate the proliferation and migration of melanocytes. When melanocytes absorb UVB energy, they can also stimulate the activity of tyrosinase, accelerate the oxidation and polymerization of tyrosine, and increase the synthesis of melanin;
2. It can promote keratinocytes to release factors that promote the proliferation and differentiation of melanocytes, such as endothelin-1 and fibroblast growth factor 1;
3. UVB has an immunosuppressive effect, which can protect migrating and proliferating melanocytes from damage.

LCD Display Screen

High-definition display screen, clear and easy to read and touch, giving you a smooth and comfortable use experience.

With the Host Base, Free Your Hands

The innovative ultraviolet light lamp and the base design make the whole medical lamp look like a desk lamp. Customers can either remove the light therapy lamp and irradiate the lesion with one hand, or plug the light therapy lamp into the base and directly place the lesion under the lamp for irradiation.

90° Rotating Lamp

The phototherapy lamp plugged into the base can be bent 90° to meet the irradiation needs of different parts of the body. Customers can adjust the angle of the phototherapy lamp according to their lesion and their most comfortable posture.

Lightweight Handheld Design

The phototherapy lamp is lightweight and can be held in one hand for a long time without feeling tired. Patients can use this product independently at home for phased phototherapy.

Large Irradiation Area

Unlike other single-lamp phototherapy devices, this product uses dual-lamp tubes to achieve a maximum irradiation area of ​​104 square centimeters, which is very suitable for irradiating lesions larger than a palm.

Unique Reflective Plate Design

The top of the lamp is cautiously designed to ensure the light is effective to irradiate the lesion skin rather than the others, avoiding the waste of life hours and fully taking advantage of the light power, save-efficient and safe to healthy skin.

Application

Visible Treatment Effect

This is one treatment case, the area of the lesion is about 25 square centimeters.

How to Use the Lamp

Treatment Frequency and dose adjustment

• Treatment Frequency: 3 time per week.
• lf the interval between two treatments is maintained within 3 days, no erythema, then increase dose as per below sheet.

Treatment Session	Dose Increase By
1-20 times	10% MED
21-X times	Depend on skin response to treatment

Maximal dose keep less than 6 MED,if reach this level,then keep dose unchanged.

• If see slight red after previous treatment,then keep the original dose unchanged.
• lf see dramatic erythema after previous treatment,then check them and adjust dose
  accordingly.
• After the skin lesions subsided, can stop the treatment immediately.
• Narrow-band UVB treat Psoriasis,suggested session is 30-35 times.
• lt may require longer treatment session to maintain the effects,especially in winter or countries and regions with higher latitudes.

Psoriasis:
3 ~ 4 times / week, 15 ~ 20 times / treatment course.
Vitiligo:
2 ~ 3 times / week, need treatment for 30 ~ 50 times or more.
Parapsoriasis:
PUVA, UVA/UVB,NB-UVB: 4 times / week, until histology improvement.

Attention Tips for Accepting 311nm Ultraviolet Phototherapy

• The following patients should not be treated with UVB radiation: patients with solar dermatitis, patients with lupus erythematosus, patients with malignant tumors, patients with xeroderma pigmentosum, patients with Bloom syndrome, patients with dermatomyositis, pregnant women, and other patients who are not eligible for UVB radiation therapy.
• Please remember to put on the anti-uv goggles before turn on the machine!
• Avoid skin trauma and friction, and patients should not wear tight clothes.
• Patients should wear sunscreen when going out and avoid strong sunlight after treatment, such as swimming at low-latitude beaches or traveling in high-altitude areas. Special attention should be paid to the fact that ultraviolet rays can damage the skin and induce and aggravate the condition.
• Avoid chemical stimulation. Patients should not dye their hair or paint their nails, and their hands should not often come into contact with irritating chemicals.
• Patients should eat a normal and balanced diet without any dietary restrictions. Try to reduce or avoid smoking and drinking, and take vitamin drugs.
