Bio oil or other oils?

Holly • Engaged. Dog mom. FTM-to-be. due Dec 22.
I use a few oils to try & keep my skin hydrated. Bio oil & Johnson & Johnson baby oil gel with cocoa and shea butter are the ones i use most often. I rub them both in very well but for a little while after im itchy. Is there anyway to prevent this? Its not an allergic reaction or anything like that. Was wondering if this happens to any one else and what you do to help it.
