My husband is 51 and has redness and itching on his eyelids, spreading to his cheeks. Is this eczema?

It is very difficult to tell you what this is without more information.
At his age, it could be a condition called rosacea, which can cause
a red, sometimes bumpy, rash over the cheeks that can be
associated with irritation of the eyelids – called blepharitis. Rosacea
can also cause flushing and a burning feeling in the face after
alcohol, spicy foods or a sudden change of temperature. He should
see his GP as the steroid creams used to treat eczema can
sometimes cause rosacea if used for too long a time.
These days I only have mild eczema, but I recently
developed blister eczema in the middle of the sole of one
foot. It doesn’t seem to respond to my usual creams and
seems to be getting bigger. Is it just more stubborn than
my normal eczema?
You may not have ‘blister eczema’, which we call pompholyx, as it
is just affecting one foot. Eczema tends to affect both sides of the
body, so you should be suspicious that an outbreak like this is
caused by something else. The first thing to come to mind is a fungal
infection, which can be quite inflamed and can cause little blisters.
You should see your GP and get some skin scrapings taken to look
for fungus.
Many people treat fungal infections (also known as tinea) with
steroids in the mistaken belief that the rash is eczema. The steroids
will damp down the inflammation in the skin and mask the
infection, allowing it to spread in the skin. They then get a much
larger patch of slightly itchy skin, often with a thin red line all the
way round the edge where the fungus is growing – this is called
‘tinea incognito’ as the typical features of a fungal infection are
hidden.
