Pop em with your fingernails? Sure it hurts but it's guaranteed to work. Pop them until blood comes out then put some disinfectant on it.
While this can work, it's not recommended.
If the spot isn't ready, meaning it's little more than a lump and is just red, then I wouldn't do it.
If it protrudes quite a bit and it's got an obvious yellow pus visible beneath the skin, then it may be fine.
Premature bursting of spots can cause scarring, which can be permanent.
If you do pop it, then I recommend washing your hands before you do so and washing your face.
Then using two cotton-buds to pop it. This is better than using greasy dirty fingers, and more accurate.
It also will clean up some of the pus/blood immediately as it falls on the cotton.
Once you've popped, squeeze until no more pus comes out. You don't want to see pus in there. If you leave it with pus in there it'll only go back to being a spot again.
And popping that once more will make it more likely to scar.
Once you've popped it and gotten rid of the pus, and it's pretty much just bleeding, then give it a wipe down with tissue paper.
Then wash your face and hands again and avoid touching the spot. You don'twant to put dirt near it and get it infected or cause another spot to appear.
You may also find that if it bleeds, it's usually not a lot of blood.
But it is not impossible for it to bleed surprisingly profusely. Imagine it being similar to a cut from an accident while shaving.
In this situation, keep the wound clean. If it's in a suitable location, like your forehead, a plaster might be helpful.
Other than that, just wash your face. Regular soap is good enough.
Witch hazel is also quite effective too.
Keep washing and the spot will recede. It might take a little while. A day or two.
Keep washing after that to prevent spots.
Remember, there's more than one factor that can cause them.
Not cleaning is one, but even if you're clean and you get sweaty, that can cause them. So, take care to clean off sweat if you've been out in the sun or exercising.
And stress can also play a part too. If you are stressed, try to relax.
