Dermatitis prevention
The terms dermatitis, eczema and rash are often used to describe the same condition. Symptoms of dermatitis include slight to marked redness, itching and sometimes some swelling.
Contact dermatitis
Contact dermatitis results from direct irritants, and is restricted to the area of contact. It is often due to contact with chemicals such as those in hair dye, nickel in jewellery, sticking plasters, perfumes or plants. It develops slowly, due to chronic exposure, and is often very itchy and red, with raised welts.Atopic dermatitis
Atopic dermatitis is common in the elbows or behind the knees. It often occurs with a family history of allergy, eczema and/or asthma, developing in early childhood. Atopic dermatitis looks like dry, flaking skin, especially early on, before scratching starts.When should you seek medical advice for dermatitis?
You should seek medical advice for this condition if:- there are signs of infection, such as a weeping area or pus;
- the skin is broken;
- the skin is very red and inflamed;
- there is a burning or hot sensation;
- the rash is spreading or lasts for more than 3 weeks;
- there are vesicles (little pimples with clear fluid);
- the area has white patches or silvery scales;
- the skin has become tough and leathery; or
- the person affected is a child.
What can you do?
If you have dry skin or a tendency to dermatitis, you should:- use hypoallergenic cosmetics;
- avoid the cause of contact dermatitis, if possible;
- pat, rather than rub, the skin after a bath or shower;
- avoid having too many showers or baths, as this dries the skin out; and
- always use a soap substitute, even when the skin is healthy. Soap substitutes are very useful if you are trying to avoid dermatitis.
