I use normal. I haven't tried EV so I can't give a good comparison but the normal seems fine enough for me.
What I do is after I have a bath or shower I rub it into my skin. If your skin is wet then it acts as a barrier (because oil and water don't mix) and 'locks in' the moisture. I've also noticed that sometimes when I've put it on my arms and rub it in then some stuff seems to come out of my pores which I believe may have been keratin plugs. But this doesn't happen very often anymore (maybe I got out all the easily extracted ones?).
So basically I use it as a sort of moisturiser. I haven't used it on my face as I don't like the feeling of it very much. I think it would be safe though as it is possible to wash the face with oil (there is a thing called the 'oil cleansing method' that I have tried a couple of times before with other types of oil but not coconut) although obviously I don't know how a baby would react to it and whether it is safe for them to ingest it.
