I wouldn't use it. Vitamin A can be toxic and lavender oil has been shown to produce gynaecomastia (breast development) in boys in a recent study, I believe that was in Endocrine News magazine; I'm steering well clear of both of those things! Despite my belly/abdomen almost doubling in size (and people still not noticing I'm pregnant!) I don't have stretch marks yet; I use cocoa body butter once or twice a day.
