Vaseline is 100% petrolatum and not everyone is allergic to it. In fact it is quite unlikely.

However, since I have very sensitive/eczema skin, I try not to use this too much.

Lips: Soften the lips but caused dark brown spots on my lips. (rectified that with Burt's Bees' lip balm. Lip discolouration is gone).

Body: When I had dry dry peeling eczema, this is good in creating a total barrier (not moisturising, different thing) the water so my skin barrier improves and heals. What this means is, it actually suffocates the skin so the skin is unable to breathe and causes clogging too. However, as I was having severe drying and cuts all over so this helps in creating a false skin barrier. Do not mistake that for moisturising.

Face: I don't use this on the face but due to excess usage on body, some got transferred to my chin and caused clogging / bumps along a large area. I am too old to have acne skin, normally my skin is pretty ok and dry-ish. I couldn't even get the vaseline off after numerous showering and face washing. In the end, I used Acne-Aid liquid cleanser on my chin to be able to remove the vaseline. Skin smoothes out immediately.

When I check out of the hospital and my doctor prescribed me some more vaseline, I just refused. Went out and got Burt's Bees Baby Bee ointment. Works wonderfully and is organic without petroleum jelly.
Another organic moisturiser option for eczema skin is raw coconut oil.

Note: since I have sensitive skin, the Acne-Aid must only be used on the spots where vaseline cannot be removed. First day, I used all over my face and my face became red (but not dried out). So beware people with sensitive skin.

To the person who said that Vaseline dried their skin out on their face, this happened to me as well. I used it for 4 months on my face and I too got severely dry skin and my skin started to feel really tight. I think it messes with oil production on our face and are face just isn't designed for something so heavy. I too found it very difficult to was off and was applying Vaseline on top of Vaseline.

I also use this as a primer for plucking my brows. Wipe it on and within 5 minutes the skin near your eyebrows is super soft and prepped for plucking! My mother used vaseline, my grandmother used it and so did my "big mama" (great grandmother) All these generations can't be wrong! xoxo

As much as I LOVE my EOS and Simple lip balms,this stuff is a classic! IT IS AMAZING! I put some on before bed and my lips feel like clouds the next morning lol! I have the ones in the tub! I prefer a tube for lips but the product makes up for the packaging! :) I would love to see Vaseline come out with new flavors besides cocoa butter!

No lip balm matches it, cheap and superb.

I love any kind of this stuff!! it is great for dry skin on any part of your body! I do recommend only using it at night as it is kind of sticky. I put it on my feet before bed and put socks on I also put it on my lips when they are feeling dry.

I typically only use Vaseline on my lips before I sleep or as a regular lipbalm, and when I awake in the morning it feels fantastically soft~
I haven't tried the eyelash one though, it sounds cool and I will go try it! It's super cheap, and it works very well on calluses / rough patches of skin. I think it's too heavy on the face though, far too thick, and it feels like I have layer after layer of makeup on - it's cakey.

I used it before on skin that was cracking on my shin, and it worked well! Two days later the snake-y look to it was gone and so...I recommend this as a necessary product in every household!

Highly recommend using vaseline around the eye area. Nightly, I apply a light layer to the skin around my eyes, and gently rub my lashes. I've been doing this consistently for about 3 months and my lashes have grown noticeable longer and thicker. I wash my face every morning, and have never had any issues applying eye makeup afterwards. Give it a try - it's so cheap, you have nothing to lose!!
On a side note, I use it on my hands (calluses from crossfit) and on my lips and highly recommend it as an overall moisturizer.

I was quite reluctant to use this as a moisturizer, since it's not a moisturizer. But I have to say, I use it on my face during the harsh canadian winter days, and it prevents my skin from getting dry, flaky and red. It doesn't make my combination skin oily, and makeup stays well on top of it. Also, it doesn't make me breakout (and I am prone to breakouts)
I also use it to contour my hairline around the face and neck when I dye my hair at home, to prevent stains.

If you live under cold cold climates, use it as a face, lips and hands moisturizer.

I prefer this in tube form; it is the best product out there to prevent chafing in unmentionable places. We often go to Florida in the summer, and it works wonders when we are outside and getting quite sweaty! It stays on and doesn't run off with the sweat (sorry about the TMI). Dirt cheap, too.
