Are chemical sunscreens safe to use with Tretinoin?

Hello. I'm male, 29 y. Fair Mediterranean skin type. My question: Is it safe to use chemical Sunscreens with Tretinoin? I read that Tretinoin thins out the outermost layer of the skin, the stratum corneum. I also read that chemical Sunscreens need an intact stratum corneum to work. Does using Tretinoin therefore render chemical Sunscreens ineffective or is it a safe combination? Thank you very much.
