Final answer:
Skin slippage, or glove formation, is the separation of the top layer of skin from the underlying tissues after death. It is a condition found in advanced decomposition and is used by forensic experts to determine the time since death.
Step-by-step explanation:
Skin slippage, also known as glove formation, is a condition that occurs after death where the top layer of skin separates from the underlying tissues. This can happen due to the breakdown of the connective tissue that holds the skin in place, as well as the accumulation of gases within the body. It is commonly observed in cases of advanced decomposition and is one of the signs that forensic experts look for in determining the time since death.
