The active ingredient in Eight Hour cream is Petrolatum ( Petroleum) . This product is over priced Vaseline, which is known not to really be the greatest thing for your skin.
It works by sealing the skin from the enviroment. While this can be useful occasionally, if this is done regularly ( say if you were using Eight hour cream as you daily lip balm) then it is going to be detrimental. The skin is unable to breath and absorb moister from the air, and gets out of the habbit of doing so. You then become dependent on using the product all the time. You are better off using a balm that helps the skin to heal and function normally.
I've used this cream for years and plan on using it for years to come. I use it every night on my lips when I go to sleep and maybe one a fortnight on my face when I've got really dry skin. It's perfect for cuticles and cuts or grazes that are healing and even pimples! Honestly this is a staple in my house and should even be in my first aid kit! Grab some today you won't regret it!
Tips: Also great to calm sunburn! The list is endless :)
