The importance of emollients in treating the increasing incidence of atopic eczema.

Atopic eczema affects 15-20% of schoolchildren and 2-10% of adults. Its incidence has increased significantly in recent years for reasons not fully understood. Environmental factors--such as exposure to soaps, hard water and allergens such as house dust mites--are thought to be important. Genetic factors are also thought to play a part. The key to managing eczema is an effective skin-care routine using emollients to increase hydration of the stratum corneum. Emollients come in a variety of formulations, and continual therapy using these in combination maximises their beneficial effects. Patient education is important, as it enhances concordance with treatment.
