Number 1, it is difficult to prevent it because every square inch of our skin contains 650 sweat glands, approximately 95-100 oil glands, 9,500,000 cells, and 65 hairs.
That gives a big chance for us to get clogged pores and end up with whiteheads and blackheads. And that’s just 1 inch of skin.
Number 2, it is hard to control skin oiliness because it can be triggered by many factors. You may get oily skin because of the food that you eat. You may also have hormones firing up and messing with your skin.
The climate may also play a part, especially if you live in humid or tropical areas. You may be using a wrong facial cleanser for your skin type. Or, you may be washing your skin too often, causing it to overcompensate and produce more oils than necessary.
Number 3, makeup and pollution can contribute to forming plugs. It is important to strip your face off of makeup and dirt before sleeping to prevent blackheads and pimples from appearing in your immediate future.
Who wants to wake up to a new zit anyway?
Number 4, we get too complacent that once we are done having a facial or once we have used pore strips to get rid of blackheads, that it will permanently keep our skin bump-free.
We need to be constantly vigilant to prevent a new sebum plug from forming.
