What is the best pimple pooping tool?

I used to suffer from acne a lot my whole face used to look like a bee hive. Then I started to use Dermalmd Blemish serum and it helped me to recover a lot and gave me an acne free face. But now when 1 or 2 pimples sometimes appear to my face I just pop it. But it leaves a mark so if anyone knows a better way to pop it or is there any kind of tool then please do suggest cause only for 1 a small pimple I don't want to buy a whole anti acne product.
