On top of that, some aqueous creams contain sodium lauryl sulphate, a detergent that further breaks down the skin barrier, which makes the skin more sensitive and the eczema worse.'So people who are applying it and leaving it on in the hope that it will soothe their dry patches, may find that the skin becomes cracked and raw instead.' Indeed, many children refer to aqueous cream as 'the stinging cream' because it irritates their skin so much, reports the National Eczema Society.
It affects the greasy and hair-bearing areas such as the face, chest and back which can be caused by a combination of overactive grease-glands, hormones and bacterial infection."So how can we banish our blemishes for good?
“Unfortunately avoidance of acne can be tricky, but it usually gets better over a year or two, so the first line of treatment is to simply suppress the inflammation until the acne disappears naturally," he says. Get rid of junk food: That means ditching crisps, sweets, chips and pretty much anything else that's loaded with fat and sugar.
This means it has to be kept moisturised or it will become overdry and crack.
'However, aqueous cream will not really help - not least because it does not contain much actual moisturiser.
'Children and the elderly have thin and sensitive skin anyway, so they are more prone to get a reaction,' he says.
'However, I see people of all ages whose eczema has got out of hand because they've been using aqueous creams rather than rich emollients. They are given only a couple of weeks' training in skin at medical school, even though skin complaints account for about 20 per cent of all GP consultations.
One study found that 56 per cent of children had an irritant reaction to aqueous cream compared with 17 per cent of children using all emollients (medical moisturisers).
'We get calls from mums saying their child won't let them apply their emollient because it stings, or that the one they are using isn't working - and invariably it turns out that they are using aqueous cream,' says Margaret Cox, chief executive of the National Eczema Society.
'GPs are also under pressure to keep their budgets in good order, and aqueous cream is cheap.' Dr Bewley says people should stick to medical moisturisers such as white soft paraffin, liquid paraffin 50 50, or emulsifying ointments, and experiment until they find one that works for them.
'Everyone is different and finding the right cream is a question of trial and error. People may find that they need a richer cream in the winter, as the skin dries out and produces less oils in the cold weather.
