Sunscreen as a barrier to tret

I’m concerned if my sunscreen is making itself a barrier between the tret and my skin. I do wash it off in the shower, use a facial wash, and try to be thorough with a facial brush. But, I’m concerned it’s not really getting the sunscreen all off, so the tret can’t get fully in.

Am I being paranoid?
