Sorry posted too early.
My son had terrible eczema from 4 months. All over arms, legs, torso and later face. Was awful.
No matter how much we moisturised, avoided common trigger foods, it did nothing.
We were referred to a dermatologist and given quite a strong steroid. I was worried at first, but she explained that in many cases kids outgrow the worst of it, and there's growing evidence to suggest that the better eczema is controlled when young, the better the prognosis for the long term. She also made the point that whilst ideally you wouldn't use steroids, the eczema itself was very bad for his skin.
Initially we had to apply to bad areas (most his body) daily. The regime moved down to every other day and eventually just the weekends.
We now only have to apply the smallest amount of steroid cream to a couple of small areas in Friday and Saturday. His body has been totally clear for about 5 months now, and it was originally horrific.
We use a vaseline based cream during the week, and his skin is generally lovely now. We get the odd flair if he's ill, but very minor.
That's not to say he's cured, but we feel it is under control. He is happier, doesn't spend his whole day scratching and it's changed his life.
Yes it's important to use steroid creams carefully, particularly the stronger ones. But provided they are used appropriately, they are very safe. As others have said, people tend to not use them properly. Applying too little and for not enough time. The skin has no chance to heal and they just go round in circles.
Also, whilst some people do have a food intolerance, most eczema is seemingly genetic and sadly requires treatment long term. But there is a light at the end of the tunnel, or at least pit stops on the journey.
