When you are tattooing, it looks like blood. It doesn't feel that the color is not in the skin. This is the most common mistake a beginner tattoo artist makes.

Teach everyone how to identify whether the tattoo is in the skin or not. In fact, it is very simple. When you have just finished the needle in the skin, immediately remove the needle and wipe off the residual tattoo color. The color you see when you see it is the depth you are on. After a few seconds, you will see red when you look.

So please don't be fooled by this red, this gray fog will disappear in half an hour.
