[Grammar] has been -ed /has been-ing/ has -ed

Hi.

The skin on my hands has peeled off.
The skin on my hands has been peeled off.
The skin on my hands has been peeling off.

Are they grammatical? the verbs make me confused.
Please explain the difference among them.
And, should I use "on" or is there any better choices? or any other informal sentences, you suggest?

The skin on my hands has peeled off.

This indicates that your skin peeled off and is gone. The peeling process has stopped. This phrasing makes it sound as if the peeling was a natural process of some sort - the skin blistered and peeled off due to sunburn or a chemical injury or some other mishap.

The skin on my hands has been peeled off.

This sentence implies that someone else removed your skin. Perhaps it was a doctor performing debridement. In any case, the skin is gone and the peeling process (done intentionally by someone) is complete.

The skin on my hands has been peeling off.

In this case, the skin is still in the process of peeling. Perhaps you washed the dishes is some particularly harsh detergent several days ago, and the skin on your hands reacted badly (a rash, or blisters). The damaged skin is slowly peeling off, bit by bit.
