311 narrow spectrum UVB ultraviolet phototherapy

Type:Uv phototherapy   Time:2018-09-25 21:22:28 311 narrow-spectrum UVB ultraviolet light therapy device is a medical device for treating psoriasis and vitiligo

The equipment has been strictly verified by many national dermatological hospitals in the world. It is safe, reliable and effective in treating various skin ailments such as vitiligo, psoriasis, eczema and atopic dermatitis. It is gradually being promoted in Europe and the United States. A high therapeutic evaluation has been obtained internationally.

Mainly used for psoriasis, vitiligo, chronic eczema, atopic dermatitis, herpes zoster, pityriasis rosea, severe seborrheic dermatitis erythematosus, palmoplantar pustulosis, alopecia areata, parapsoriasis, chronic ulcers of the skin, sputum Treatment of granuloma, various light diseases, etc.

It avoids the side effects caused by the use of photosensitizing drugs, has high light output intensity, no phototoxic side effects, good safety and tolerance, has no significant effect on normal skin, and avoids skin burns caused by traditional phototherapy. The probability of carcinogenicity.

The 311 narrow-spectrum UVB is a new treatment system for vitiligo. By irradiating the skin lesions with ultraviolet light of a certain wavelength, it produces a photochemical reaction or regulates the immune reaction, thereby achieving the purpose of treating certain stubborn skin diseases.

Traditional phototherapy emission wavelengths range from 280 to 330 nanometers. Clinical studies have shown that light energy below 300 nanometers can cause severe burns and increase the risk of skin cancer. Therefore, the 311-312 nm wavelength range of the 311 narrow-spectrum UVB emission is considered to be the safest and most efficient light.

Narrow-spectrum UVB (311 nm) irradiation activates tyrosinase activity and promotes melanin formation. 2-3 times a week, need to adhere to treatment 30-50 times, or even more treatment. Especially for facial rashes have a good effect. For the trunk and limb rash, the effect is poor and may require a longer course of treatment. The clinical results in countries such as Europe and the United States show that the total effective rate is over 80%. Clinical practice shows that the efficacy of 311nm black light therapy is better than that of broad-spectrum black light therapy. The incidence of erythema reaction is low, and the disease is relieved for a long time. The curative effect is similar to PUVA, but no medication is needed.
