What needle size is used for subcutaneous injections?

Explanation:
Subcutaneous injections target the fatty tissue just beneath the skin, so you want a needle that penetrates without going into muscle and with minimal discomfort. A smaller bore needle, like a 25-gauge, is thinner and causes less tissue trauma, which is ideal for this shallow, fatty layer. Larger gauges (lower numbers) such as 18, 20, or 22 gauge are thicker and are typically used when deeper penetration into muscle or faster flow is needed, as in intramuscular or intravenous injections. So, the 25-gauge needle is the best fit for subcutaneous injections because it provides a gentler, appropriate depth while reducing pain.
