Actually, in general, when the killer removes such a large piece of skin, operating with gloves is obviously not as convenient as without gloves.
Moreover, from the cut marks and thickness of the skin, it's clear the person is not skilled with a knife.
They don't seem to be a good chef, nor a doctor used to handling a scalpel.
The possibility of them not wearing gloves is quite high.
Additionally, after the killer treats the skin for preservation, they also have to paint on it, making the possibility of wearing gloves even lower during this process.

This is the reverse thinking of collecting fingerprints from the skin.
Collecting fingerprints from skin is not done directly on the skin, but by using certain methods to transfer the fingerprints.
In this regard, Lu Chuan feels a bit lucky.
Because the transparent resin material on the skin can serve this purpose.
