this is hard to explain, but when i'm giving an intradermal injection i try to slide the needle just under and flat with the skin. if you do this right, you can see the bump formed by the shaft of the needle through the skin. you really can't have much of a slant to the needle going in or you will end up in the sq layer. i try to think of it as putting a straight pin into a piece of fabric that i have lying on a table. you just want the needle to go through the fabric and not the table. so, what you end up doing is once you pierce that fabric you have to lower the needle so it's almost parallel with the table in order to continue pushing it through into the fabric. otherwise, you will get a scratch in the top of the table, or if it's a person, go deeper into the sq area. does that make sense to you?
