You know, I"m not a big fan of these treatments. And I have red that, for example, if you squeeze out a black head you leave a hole that sometimes never goes back verses if you simply use astringent and cleaner, the blackhead will clear and the hole or pore that is opened will close. Does that make sense?
I'd skip those treatments and yes, see a dermatologist. But remember, a few pimples here and there is not abnormal. I tend to notice things with relation to my hormones. As they shift with my cycle, I have an occasional break out. I keep it clean and they go away until the next month around the same time. Joy, right?
