I used to pop my pimples a lot (yes, I know, biggest acne sin) but only if it was a big, bright whitehead. I would use a needle just like recommended. But, I was told that seeing blood and clear liquid were actuallygoodthings, because it meant all pieces of infection and bacteria were oozing out. Now I just learned from acne.org that blood and clear liquid are bad signs. So, two questions:

1. What is the clear liquid?
2. Why is seeing blood and this clear liquid a bad thing when popping zits?
