Vaseline is just a petrolatum jelly and a lot of creams and moisturisers have this as a component. The problem with Vaseline is that it’s basically pure petrolatum and so blocks the skin completely.

You rarely want to block the skin completely. The uses some other people noted, like stopping bleeding, is one of those uses.

The truth is that I rarely recommend Vaseline because of how limited it is on skin use.

I recommend people look into Aquaphor by Eucerin, which is only about 40% petrolatum and moisturises a bit better. I always travel with a very small container (just a tiny bit) of the stuff. It’s useful if you have any skin conditions (flaked skin, rashes, etc) that you might want to deal with pronto.

Aveeno (a very good brand for skincare) also make very similar heavy creams.

Long story short, no, Vaseline is pretty bad choice for skincare because it just blocks all air exchange. There are better choices. You often do want petrolatum…just not 100%.
