牛皮癣概述

Psoriasisis a chronic skin condition resulting from an autoimmune disease in which your immune system produces too many skin cells. The cells accumulate on the surface of your skin. As the skin cells shed, they form red welts that are thick and raised and may have silvery scales. The welts can be painful or itchy.

Common treatments include topical medications that reduce inflammation, and oral or injected medications that suppress your immune system. However, another form of treatment for psoriasis involves one of the most natural elements on earth: the sun.

The sun’s ultraviolet rays are made up of UVA and UVB rays. UVB rays are more effective at treating psoriasis symptoms because they slow the rapid rate of skin growth and shedding.

虽然阳光可以使牛皮癣有益,但您应该小心保护自己免受晒伤。牛皮癣主要袭来了轻皮的人。他们对晒伤和危险形式的癌症感到更大的风险黑色瘤。在光疗法的医疗环境中没有监测自然晒日光浴。和药物可能需要增加光敏性。这可以提高晒伤和皮肤癌的风险。

治疗通常在中午曝光10分钟。每天可以逐渐将您的暴露时间提高30秒。

即使你想要你的皮肤吸收太阳的光线,你也应该穿防晒霜。对于最好的(和最安全)的结果,请遵循以下提示:

  • 将广谱防晒剂应用于未受影响的皮肤的所有区域。
  • Wear sunglasses.
  • 当太阳最强时,自然阳光治疗会话。
  • Stay outside for only 10 minutes at a time to reduce the risk of sun damage. As long as your skin can tolerate the exposure, you can slowly increase your sun exposure by 30 seconds to 1 minute each day.

The sun not only helps clear psoriasis symptoms in some cases, but also it makes your body produce more vitamin D.

光疗法is a treatment for psoriasis that uses natural or synthetic lights. You absorb the ultraviolet rays through your skin as you sunbathe outside, or by using a special light box.

使用人造UVB源的处理在规则的时间表中管理设定时间时最成功。治疗可以在医疗环境或家中进行。

您的医生可以选择用UVA射线代替UVB对待您的牛皮癣。UVA射线比UVB短,更深入地穿透你的皮肤。由于UVA射线在清除牛皮癣的迹象方面不有效,因此将一种称为牛头烯的药物添加到光疗中以提高有效性。在您的UVA治疗之前,您将采用口服形式的药物或在受影响的皮肤上使用局部处方,帮助您的皮肤吸收光线。短期副作用包括皮肤的恶心,瘙痒和发红。这种组合处理通常缩写为PUVA。

Puva用于治疗中度至严重plaque psoriasis。当局部处理和UVB疗法没有成功时,它可能会使用。厚厚的牛皮癣斑块对Puva响应很好,因为它在皮肤上吸收更深。手和脚下牛皮癣通常用Puva Therapy.
