It is important to use the correct amount of topical steroid for your eczema, as instructed by your healthcare professional. Topical steroids should be applied with clean hands so that the skin just glistens. It can sometimes be difficult to judge how much steroid to use and there are guidelines on the amount required to cover body areas that are affected by eczema. These are based on the Finger Tip Unit (FTU), and explained in detail in our fact sheet which you can download as a pdf from the related documents to the right of this page.
Phototherapy or light treatment is an effective treatment for eczema. With phototherapy, various wavelengths of sunlight (UVB, UVA, combined UVA/UVB, UVA1, or narrow-band) are administered in a unit that is similar to a telephone booth but which is lined by fluorescent appearing light bulbs. The type of phototherapy that you will receive will be determined by your dermatologist. It is usually administered twice weekly. Possible side effects of phototherapy are redness, sunburn, or dryness. Long-term side effects, which are more likely with white skin, are possible skin cancers and enhanced aging.
