What gauge is commonly used for intradermal injections?

Explanation:
A very fine needle is used for intradermal injections because they are placed just under the surface of the skin. The thin needle minimizes tissue disruption and depth, helping to keep the medication in the superficial dermal layer and to create the small wheel (wheal) that indicates correct placement. Using thicker needles would penetrate deeper, cause more pain, and risk going into subcutaneous tissue or muscle, which is not desired for this route. So the best choice is the finest gauge commonly available for injections, while thicker gauges are reserved for subcutaneous or intramuscular injections.
