  • dimethicone vs vaseline?

    Posted by prizes2011 on March 7, 2016 at 11:15 pm

    Vaseline does a great job of moisturizing my skin, but it makes it somewhat greasy and shiny. Is dimethicone effective at preventing water loss? Is it absorbed into the skin (not like vaseline)?

    Yes, Dimethicone can prevent water loss.  

    No, it is not absorbed into the skin.

    How effective is it compared to petroleum jelly? Will penetration enhancers help absorb these occlusives or are they too big either way? Thanks for helping me!

    You wouldn’t really want dimethicone or other silicones inside your skin. Some silicone types contain volatile components that, when placed inside the body and reaches the bloodstream, may cause serious trouble. I think it is best to use silicones on the epidermis as a carrier for actives and as emollients.

    Adding an actual “penetration enhancer” to any cosmetic automatically turns it into an unapproved new drug, and makes it illegal to sell. It is then incredibly, almost insanely, risky to use it on your own skin, regardless of what is in that cosmetic. You could die, or cause severe harm to yourself.
