How should I use peeling gel?

How can I use a peeling gel effectively on dry skin?

I'm thinking of buying the peeling gel in the picture. However, I'm worried that I might buy it and not use it. I'm really conflicted about this, so I asked about it before, but I didn't get the answer I was looking for. I need to exfoliate, but I want to know the proper way to use it so that it doesn't irritate my dry and sensitive skin.

I am wondering when and how to use a peeling gel, and what I should pay attention to for skin care after use.

Also, are there any peeling gel products specifically suitable for dry skin?

I would also appreciate it if you could let me know any precautions or tips for use.
