Of course, when something seems too good to be true, we have to try it out. Before bed, I washed my face and applied some benzoyl peroxide cream on the monster zit on my chin. I then dabbed a thin layer of Vaseline over it and went to bed. The next morning, the pimple’s size was visibly reduced and instead of a red, dry patch around the zit, I had smooth hydrated skin (which also made the zit less noticeable). I repeated this for a few more nights until the bump disappeared. So it worked like a charm. But how?
“If you have acne, you want your skin to be well-lubricated at all times to help your skin barrier repair itself,” says Yale dermatologist Mona Gohara. “Otherwise, you’re just going to create more acne and breakouts.” Counter to conventional thinking, slathering skin with such a heavy salve-like product won’t cause you to breakout. The Journal of Cosmetic Science (PDF) concluded years ago that petroleum jelly is 100% non-comedogenic, meaning it will not clog or block your pores.
According to the dermatologist, the petroleum jelly not only seals in the medicated products you applied to the zit, it also creates a barrier on your skin which traps moisture within and prevents the skin from drying out and flaking. It all adds up to helping the skin heal itself at a faster rate. And isn’t that what we’re all looking for when we’ve got a zit bringing us down?
