Subcutaneous injections are delivered into which layer?

Explanation:
Subcutaneous injections go into the hypodermis, the layer just beneath the dermis that mostly consists of adipose (fat) tissue. This tissue is ideal for slower, more controlled absorption, which is why medicines like insulin or certain anticoagulants are given there. The epidermis is the outer protective layer, and the dermis sits above the hypodermis; injections into those layers would be intradermal or intramuscular rather than subcutaneous. The term subepidermal isn’t used for injections in clinical practice.
