Uv led 310nm 4545 uvb led vitiligo led phototherapy

UVB phototherapy is a common treatment in dermatology.UVB belongs to UVB.When light is irradiated to the skin surface, it can be absorbed by tissues and converted into heat energy, chemical energy and biological energy to cause a series of physical and chemical reactions and biological reactions. UVB phototherapy can be used in clinical treatment of psoriasis, pityriasis rosea, vitiligo and other diseases.The effect is clear.Common adverse reactions after treatment include dry skin, pruritus, erythema, pain, pigmentation, etc.These are all temporary.It can improve and disappear after treatment.

UVB phototherapy is a pure physical therapy for skin diseases such as vitiligo and psoriasis by using narrow-spectrum medium wave ultraviolet light with a wavelength of about 311 nanometers.Clinical trials have shown that it has a significant effect on some early, small patients.Phototherapy matters needing attention are described as follows:

1, UVB phototherapy can be separated by sunshine once.When lighting, pay attention to blocking the normal skin (can use thick cloth or cardboard to dig holes or apply sunscreen oil, sunscreen and other methods) to avoid the normal skin dark, affecting the appearance, and fading slowly.Pay attention to wear goggles to avoid UV damage to the eye fundus.

2. From a few hours after phototherapy, the white spot skin appears reddish (refers to light pink) and slightly hot (not very red, itchy and painful). Before the next light, the skin color will recover best, indicating that the light time is appropriate.When there is no reddish phenomenon, usually the accumulation of ultraviolet light dose is not enough, to consider: the height of the lamp from the skin to keep stable (usually 2 cm and above the height can be);To appropriately extend the light time, each time can be increased by 3-5 seconds.Never think erythema is red more, ache more, had been passed over abdurably more, have blister even, that is the serious burn that ultraviolet light is right cutaneous, inhibited the activation of T lymphocyte likely, also damaged hypodermic melanin cell, generate melanin hard instead.

3. In addition to determining the starting time, the increasing time and the stabilizing time of the light are determined according to the skin erythema.The general principle is: in the white spot is not red, light small dose, short time to increase.To understand that not red is not equal to no treatment: you shine dozens of seconds, there are dozens of seconds of ultraviolet treatment;Reddening is not curative: it is the skin's inflammatory response to intense ultraviolet light.Efficacy is usually assessed after 3-6 months and is characterized by retraction of the margin of the leukoplakia and the appearance and connection of pigmented islands within the leukoplakia, gradually covering the leukoplakia.

4, avoid light time is too long, the dose is too large, so that the skin appears red and swollen, severe itching pain, even blisters and other inflammatory symptoms, affect the treatment, but also seriously damage subcutaneous melanocytes, destroy melanin production.Light should be stopped at this point, and the light therapy should be resumed after the skin has recovered.Individual patients because of phototherapy damage to the skin, there may be a "homomorphic reaction", that is, leukoplakia expansion.Be sure to pay attention to light therapy do not damage the skin, harmful and not beneficial.Skin after light peeling, swelling, itching pain.Can be replenishing water, cold compress, but also daub anti-inflammatory ointment (such as: blue oil hydrocarbon ointment, glucocorticoid cream, erythromycin ointment, more than 100 Bang, etc.) anti-inflammatory.

5. Phototherapy also has skin light resistance problems, which vary from person to person.Usually light after 2 courses of treatment, the possible curative effect is not obvious, can be suspended for 1-2 months, and then restore phototherapy.When lighting is resumed after stopping for various reasons, the radiation dose should be appropriately reduced, that is to say, the initial lighting time should be shorter than before, so as to prevent lighting injury.

6, vitiligo treatment is a slow process, usually UVB phototherapy at least 1-2 courses (3-6 months), to assess the efficacy.The proliferation of melanocytes and melanin generation, movement, aggregation, the formation of pigment island, covering the white spot is a period of time, it is impossible to light a few times on the immediate effect.So patients do not worry, adhere to phototherapy is very necessary.

7. Phototherapy combined with external medication in the treatment of vitiligo can improve the efficacy.Psoralea fat liquid, Vialu and other photosensitive drugs can be applied half an hour to one hour before phototherapy, skin test beforehand.Putbi, halomethasone and other topical ointments can be interspersed in the morning and evening after phototherapy for two hours. A thin layer can be rubbed evenly and infiltrated. It is also a waste if the ointment is not absorbed.Some topical ointments have anti-inflammatory properties that help to restore the skin after phototherapy.During phototherapy, in order to avoid possible oxidative stress reaction, vitamin E, coenzyme Q10 and other antioxidant drugs can be added.
