[[Phototherapy|Light therapy]] using [[heliotherapy]], balneophototherapy, [[psoralen]] plus UVA ([[PUVA therapy]]), light has tentative support but the quality of the evidence is not very good compared with narrowband UVB and UVA1.<ref>{{cite journal | vauthors = Gambichler T | title = Management of atopic dermatitis using photo(chemo)therapy | journal = Archives of Dermatological Research | volume = 301 | issue = 3 | pages = 197–203 | date = March 2009 | pmid = 19142651 | doi = 10.1007/s00403-008-0923-5 | s2cid = 29045951 }}</ref> [[UVB]] is more effective than UVA1 for treatment of atopical dermatitis.<ref>{{cite journal | vauthors = Meduri NB, Vandergriff T, Rasmussen H, Jacobe H | title = Phototherapy in the management of atopic dermatitis: a systematic review | journal = Photodermatology, Photoimmunology & Photomedicine | volume = 23 | issue = 4 | pages = 106–112 | date = August 2007 | pmid = 17598862 | doi = 10.1111/j.1600-0781.2007.00291.x | s2cid = 25684608 | doi-access = free }}</ref>

Overexposure to ultraviolet light carries its own risks, particularly that of [[skin cancer]].<ref>{{cite news | vauthors=  Stöppler MC |title=Psoriasis PUVA Treatment Can Increase Melanoma Risk |url=http://www.medicinenet.com/script/main/art.asp?articlekey=548 |date=31 May 2007 |publisher=MedicineNet |access-date=17 October 2007 |url-status=live |archive-url=https://web.archive.org/web/20070929092825/http://www.medicinenet.com/script/main/art.asp?articlekey=548 |archive-date=29 September 2007  }}</ref>
