Can I apply sunscreen after applying regeneration cream?

Tomorrow is the first week since I had my flat warts removed, so I'm planning to take off the Duoderm and apply regenerative cream.

When going out, can I apply a regenerating cream, give it some time to absorb, and then apply sunscreen on top of it?

And since I came home and applied sunscreen, I need to double cleanse. Is it okay to use cleansing oil?
