Should I go back to using a loofah?

I follow dermatologists on social media and stick to their advice on not using a loofah. All of them suggest using chemical exfoliation over physical. Recently I've noticed that my skin is getting darker due to dead skin cells. I'm not sure if my current method is helping me at all. In the past, maybe till last year, I used to do both (BHA and loofah) on different days so as not to irritate my skin. Should I go back to doing that? I never had any issues while sticking to that routine.
