I've always used 23 gauge needles but have read so many great reviews about 25 gauge needles and how they cause less scar tissue. So I figured I'd give it a try. The 25 went in smooth as advertised but i swear it took felt like it took 4 or 5 minutes to inject 2ml.
To you have used 23 and 25 gague needles do you notice a big difference in the time it takes to inject?
