    What about using petroleum jelly to keep your lips soft?

  • jmboss

    I find that salt sprays for dry nostrils are just not enough.

    While reviewing the cited sources, I wondered if plant based oils such as olive oil would be a safe alternative to animal and mineral based oils?

    • Dan

      He answered that exact question at the end of the video.

    I get really dry skin. What would you recommend? I have a strange habit to rub my fingers and use a lot of petroleum jelly. I can’t stop it and it wears out my finger pads. What would you suggest.

  • Sebastian

    Yeahh, I’d like to know an alternative that works though Dr Greger… When I have cracked lips from the intense cold of northern UK I use this stuff to stop my lips cracking and bleeding.

    What would you recommend?

      Hi Seb, I also live in the UK and would recommend buying an organic unrefined shea butter from ebay. It’s great, melts inbetween your fingers and works so much better than petroleum jelly!

    I live in Canada with very cold winters. Recently my nostrils have been so dry that they started bleeding. Vaseline helps a bit, but the problem doesn’t go away. I’ve tried Rhinaris nasal gel as well with the same result. One of my nostrils has scabs and does not seem like it’s going to heal any time soon. Help!

      Hi, J.

      Ugh — how frustrating! I wish I had a solution! Please ask your doctor for a solution, perhaps she or he has more info? Some folks use avocado oil and coconut oil on their skin, not sure about in nostrils, as Dr. Greger pointed out it may be any oily substance in the notice that could be problematic. Sorry I cannot help more!

    What about putting vaseline on your lips?

    And for our skin generally? Is it unwise to use petroleum sauves on our skin?
