Do you know that there is light therapy for eczema? Before we go further into this, you should know first about the light therapy for skin used for eczema, how many kinds of light therapy, and the risk.
About eczema light therapy
For your information, eczema light therapy is a kind of therapy that uses ultraviolet or UV light to treat eczema, especially the itching and skin rash. It is said that by using light therapy, it will suppress the overactive skin immune system cells that can lead to inflammation.
Generally, those who suffer from eczema can use natural sunlight to reduce the symptoms of eczema. However, artificial UV light can help better and considered as the best treatment because it can be controlled. This light therapy is safe and effective for adults and children over 12 years old that suffer from moderate to severe eczema that cannot get treated with other treatments.
Types of eczema light therapy
Furthermore, there are three kinds of light therapy for eczema. The first one is Broadband UVB light therapy or phototherapy. This kind of light therapy uses type B ultraviolet light that is proven effective to treat skin conditions since the 1920s. In this therapy, patients will have to stand in the lightbox three times per week. The total of this therapy is around 20 to 30 treatments and the duration will increase each time until the skin becomes pale pink.
The second one is UVA light therapy or phototherapy that uses type A ultraviolet light. For your information, this type of ultraviolet light can be found in the sunlight. However, the UVA acts differently from the UVB. Thus, for this light therapy to work best, you need to take psoralen one hour prior. With that being said, the combination of UVA and psoralen is called PUVA light therapy. This light therapy will be given two or three times per week for a total of twelve to fifteen weeks. Those who cannot tolerate PUVA light therapy will suffer from nausea.
The last one is Narrowband UVB light therapy. This kind of light therapy is effective and has fewer side effects. Also, this light therapy uses a quite small part of the UVB spectrum. Thus, this therapy is considered safer than other treatments.
Of course, everything has risks. Here are some risks of light therapy for eczema:
- Skin damage
- Skin cancer
