Nor sure about the breakdown part, but Retinoid (prescriptions such as Retin-A) go deep into the skin down to the dermis. An oil sits on top of the skin. I don't see a problem, but you don't want to counteract the proven benefits of a prescription Vitamin A, so try alternating nights, vitamin A one night, oil the next.
