Will applying Vaseline after Tretinoin significantly reduce the effectiveness of the Tretinoin?

I use Tretinoin for anti-aging purposes, but my skin gets dry in the winter. I understand why Vaseline would dilute the effectiveness of Tretinoin if applied before Tretinoin, but would it essentially “lock it in” while also preventing moisture if applied after Tretinoin? Or even 20-30 minutes after applying Tretinoin?
