E45

While this is targeted at those with inflamed, irritated or dry skin conditions, such as eczema and psoriasis, it’s effective and gentle, so anyone can benefit. As we get older and lose the protective properties of collagen and elastin, our skin can become drier so it’s a good choice for the elderly to prevent dry itchy skin. Children may also benefit, as they often have more sensitive skin or need moisture replaced from activities such as swimming.

There is no one right answer. In general, most eczema-targeted skin products contain the same main ingredients: white soft paraffin and light liquid paraffin, but in different quantities. But different products may add in other types of moisturiser, or exfoliants – Cetraben contains citric acid for this purpose – and antimicrobials. So, it really is about trying a product and seeing if it works for you. E45 may suit you if you're looking for a simple formula or are using products with active ingredients alongside.

In terms of formulations, ointments are recommended for very dry, scaly or rough skin, as they last much longer between applications and provide more skin repair. But they have a greasy texture and may not be agreeable to everyone. Creams and lotions are less greasy but will need frequent reapplication.

Some skin products use an alternative to paraffin, such as oatmeal in the Aveeno range.

E45 is very well-tolerated. However, anyone with any allergies to any of the ingredients listed, such as paraffin should avoid E45. E45 should not be applied to a fresh burn.

E45 contains white soft paraffin which is flammable. This may transfer onto clothing or bedding, so care should be used to avoid open flames.

The ingredients in E45 may cause allergic or sensitivity reactions in some. Side effects include burning, stinging, itching, redness of the area. In this case, stop using it, remove it from the skin by washing with water and a mild soap, or wiping away with a towel. Seek medical advice if necessary.
