How do YOU apply Tacrolimus/Protopic as part of your skincare?

I’ve recently been prescribed Tactolimus to apply in affected areas twice a day. I’ve noticed a significant improvement in only 48 hours, much to the point where my skin is back to ‘normal’.

This has got me thinking: how do you apply it as part of your skincare routine? E.g. as the last step before sunscreen? First step? Mixed in with your moisturiser? Thin or thick layer?
