Can E45 Cream be used on black patches and dry skin on your feet?

I have black patches on my skin and is very dry especially my feet so will E45 do the job properly.|||E45 is great, it can be used anywhere (except the scalp) and its very mild so it wont make anything any worse.|||Dry skin doesn%26#039;t normally turn black and I suggest you go see your doctor as it sounds like it may be a skin infection and will need some anti biotic cream . E45 is a good general moisturising cream for dry skin , but get it checked by doctor first
