Many types of eczema are often caused by environmental irritants and allergens resulting in itching, dryness or cracking of the skin; the treatment can involve identifying and avoiding the cause, for example grass pollen or house dust mites. Products, such as emollients applied to the skin to form a barrier, can help alleviate the symptoms. More information is available from the National Eczema Society on www.eczema.org.

Are all eczema treatments considered to be medicines?

Depending on the mode of action, topically applied products for the treatment of eczema can either be physical or pharmacological. Products which work by using physical actions such as those achieved through an emollient (which act as a barrier), are likely to be considered to be medical devices, and those with a pharmacological action are likely to be considered to be medicines.    Marketers of topically applied products are therefore recommended to obtain advice from the Medicine and Healthcare products Regulatory Agency (MHRA) about whether their product is a medical device or a medicine prior to making claims to treat eczema.

Which types of claims are likely to be a problem?

In 2011 the ASA upheld complaints about a skin cream which made references to dry skin, eczema and psoriasis. The advertisers believed consumers would understand that the cream could help to relieve the symptoms of the conditions, rather than cure them. However, the ASA considered that the advertisers were making medicinal claims for an unlicensed product and subsequently ruled the treatment claims problematic (Foot Care, 11 May 2011).

Some complementary therapies claim to treat or relieve eczema. To date, CAP has seen no convincing evidence for the effectiveness of any complementary therapy in treating or preventing eczema and no signs that the efficacy of conventional steroid treatments can be matched (Jackie Ginger Reflexology, 28 September 2011; A Better Being, 3 October 2012). Marketers of other products, such as vacuum cleaners and water softeners, should ensure they hold adequate substantiation before making claims that they can treat the symptoms or causes of eczema (Harvey Water Softeners Ltd, 31 August 2011).

What about food intolerance testing?

Marketers should avoid making claims that causes of eczema can be established through food allergy testing unless they hold robust clinical evidence to demonstrate that such testing can demonstrate a proven link.

What about cosmetic products?

As a rule of thumb, cosmetic products are suitable for everyone and should not be targeted at sufferers of particular conditions. While marketers may claim their products have a “sensitive formula” or are “suitable for dry and sensitive skin”, they should be wary of making claims that their product is for “sensitive skin conditions” or similar.
