I finished my Beauty Water and replaced it with this as the first step in my routine.

I apply it with a cotton pad. The liquid feels a little thick for this, and I feel like I may be wasting some product this way. It's a good enough value that this isn't much of a concern for me though.

And it achieves my goal: to gently exfoliate dead skin/any remaining cleanser or hard water scale. It hasn't caused any irritation for me; it seems like a relatively gentle product. I think there's a good chance I'll repurchase when I finish the bottle.
