what is subcutaneous
The subcutaneous tissue (from Latin subcutaneous, meaning beneath the skin), also called the hypodermis, hypoderm (from Greek, meaning beneath the skin), subcutis, or superficial fascia, is the lowermost layer of the integumentary system in vertebrates.ust as the subcutaneous tissue can store fat, it can also provide good storage space for drugs that need to be released gradually because there is limited blood flow.  Skin popping  is a slang term that includes this method of administration, and is usually used in association with recreational drugs.
