I've always used aveeno for myself so be able to have the baby range was great, one tube goes along way as only a small amount is needed. Too much can leave a bit of build up in creases of legs but still fine. Would highly recommend as aveeno is great for sensitive skin and being oatmeal based very unlikely to irritate any skin.
Just like another barrier cream which is white it leaves a white cream on the surface of the skin to start with, it disappears soon and leaves the skin protected.
I even use this on my babies face to help the dryness from milk covered cheeks every feed which works well.
