Side effects of ultraviolet light therapy device

Many people don’t know much about ultraviolet light therapy devices. As the name suggests, this device achieves treatment through ultraviolet light irradiation and is a type of physical therapy. Some people worry about whether this treatment method will have side effects. In fact, there is no need to worry too much. There may be side effects, but if you strictly follow the doctor's instructions and the irradiation time is not too long, the side effects will be very small. Let’s take a look at this treatment method.

Ultraviolet light therapy device is specially used to treat psoriasis and vitiligo. It is a physical therapy technique that uses ultraviolet rays to irradiate the human body to prevent and treat diseases. Ultraviolet light therapy is one of the effective methods for treating MF, especially early MF. Commonly used ultraviolet rays include PUVA, broad-spectrum ultraviolet B (BB-UVB) and NB-UVB. NB-UVB was first used in clinical practice in 1984, initially mainly for the treatment of psoriasis vulgaris. Its efficacy is significantly better than BB-UVB and equivalent to PUVA, but with fewer adverse reactions.

The ultraviolet light therapy device uses narrow-spectrum UVB technology with a wavelength of 311nm. Clinical trials have shown that narrow-spectrum medium-wave ultraviolet rays with a wavelength of around 311nm have significant therapeutic effects on the treatment of skin diseases such as vitiligo and psoriasis, and are a pure physical therapy. Ultraviolet light therapy devices can emit medium-wave ultraviolet rays with a wavelength of 311nm. Most of the ultraviolet rays at this wavelength can be absorbed by the epidermal tissue, and thus have significant biological effects on the skin and other tissues. Ultraviolet rays have good drying, sterilizing and anti-inflammatory effects. They can directly kill bacteria or viruses in superficial tissues, accelerate blood circulation, relieve pain, and promote epithelial regeneration. Therefore, ultraviolet irradiation treatment can directly kill

The herpes virus prevents secondary bacterial infection, promotes blister absorption, relieves pain, and accelerates the repair and healing of skin lesions, thus playing a good therapeutic role. The study also found that ultraviolet light therapy can significantly inhibit the activity of epidermal Langerhans cells and other antigen-presenting cells, reduce inflammatory responses, improve local blood circulation, promote rash healing and relieve pain, etc., with few adverse reactions and simple treatment.

Ultraviolet light therapy devices are suitable for middle-aged and young office workers who cannot see a doctor on time and are busy with work. Special groups who have limited mobility and cannot go to hospital for treatment on their own; patients in remote areas with inconvenient transportation, for whom going to hospital for treatment is time-consuming and costly. It has obvious therapeutic effect on patients with psoriasis and psoriasis.

Ultraviolet light therapy devices are also suitable for patients who are receiving treatment in the hospital but need intensive treatment of certain affected areas; patients who need treatment of a small area of affected areas; patients who need to ensure corresponding privacy; and patients who have high mobility at work and need to carry treatment with them. Ultraviolet light therapy can be used for this group of people.

People with psoriasis vulgaris, vitiligo, chronic eczema, neurodermatitis, atopic dermatitis, palmoplantar pustulosis, pityriasis rosea, alopecia areata, parapsoriasis, chronic skin ulcers, mycosis fungoides, and various photoreceptor diseases.
