- Phototherapy uses UVA, UVB, or a combination of UVA and UVB.
- Psoralen plus ultraviolet light therapy (PUVA) uses UVA light along with psoralen medicines, which make the skin more sensitive to UV light.
Too much sun exposure and light treatment (such as with UVA or UVB treatments) increases your risk of skin cancer.
Complementary medicine may be helpful for treating atopic dermatitis. Some small studies showed benefit from these treatments. But there isn't clear scientific evidence to show that they help. Examples of complementary medicine for atopic dermatitis include:
- Dietary supplements of essential fatty acids (EFAs), such as fish oil or evening primrose oil.
- Creams that are put on the skin. These creams contain St. John's wort or vitamin B12.
- Chinese herbal therapy. But herbal therapies may also contain substances that may cause liver or heart problems.
If you are interested in these treatments, talk to your doctor. Ask about the treatments' use, their effectiveness, and any possible interactions related to other medicines you are taking.
