Although healthcare professionals recommend the use of bath products to ease the symptoms of eczema there is no research to back up its effectiveness, according to a report.
Medical News Today (MNT), reporting on an article in the Drug and Therapeutics Bulletin, said that these products, which more often than not contain liquid paraffin, are not sanctioned by official research findings.
Directly-applied topical skin treatments are commonly prescribed by healthcare professionals and research has shown them to be beneficial to patients in preventing moisture loss and forming a protective barrier on the skin.
The MNT report stated NHS spends 40 per cent of its total eczema treatment costs for pre-school children on bath emollients.
The DTB said: "Given that bath emollients are expensive and the NHS spends a considerable sum on them, we believe their use requires proper evaluation."
Emollients allegedly reduce the need to prescribe as many steriods for the treatment of the inflammatory skin disease.
NHS figures state that up to a fifth of children have eczema in early life alhough in about 70 per cent of cases it clears up during their teenage years.
