You can actually buy a silver metal specially shaped tool that pops your pimples without spreading bacteria. It has a hole in the slightly domed centre & you line the hole up over the pimple & apply pressure. It pops in the done part & you wash the tool. You don't bruise the delicate skin & you don't spread infection from your fingernails to other parts of your face. You buy it from the chemist but I can't tell you how much. Probably less than 15 dollars.
Blackheads aren't easy to remove. If you have them on your nose you can use the strips and it help some. But, there is a lot of products that claim they work but I don't really think they do. You just really have to pop them.
