Stop popping your zits, it’s really that simple.  I mean I had one zit that I thought was a normal zit, no, it’s one that burrows deep below the surface and it’s guaranteed to cause scarring even if you just touch it in general terms.  That’s never obviously good. But even with normal zits, you can cause serious damage and scarring, and frankly if you’ve ever noticed, when you do that, it causes the zit to often get infected, to break out more, and to stay around longer in general.  This is because a lot of things build up in your nails, on your fingers, etc.  It is not really sanitary in general terms.  You can disinfect, and it’s better to use a hot wash cloth instead of just your fingers.  But at the same point in time, you are inevitably causing a certain amount of skin damage when you do this, and it’s far better to just leave it alone and not pop the zits in any way in the first place to avoid all sorts of problems and side effects in general.  If you feel the need, let your dermatologist determine if it’s even a good thing for him to use some of his tools.
