Sunscreen absorption
Does what we use on our skin get absorbed?
The conventional personal care industry has long maintained that what we use on our skin is not absorbed into the body via the skin. Research conducted by geochemist Brian Gulson, of Sydney's Macquarie University, has provided conclusive evidence that zinc oxide particles can be absorbed by the body and remain there for extended periods of time.

As it has long been thought that creams and potions, rubbed into the skin, could not permeate the upper layers, of the skin, this research is significant as that concept has been called into question. Whilst the amounts of zinc present, in participants blood and urine after zinc oxide application, was minimal amounts, Professor Gulson is still warning people who use a lot of sunscreen, over an extended period, that they could be at risk of having elevated levels of zinc in their body.
There are those that have used the 'precautionary principle' with regards to personal care products, as I have for the last five years. That is by choosing to use certified organic skin care products, which are, free of synthetic chemicals, that can have detrimental side effects. I also use organic plants and oils, such as coconut oil, or sesame oil to massage, with certified organic essential oils.

Do you know what is in that, sweet smelling body lotion, or the creams, that you use on your body on a daily basis? Could it be time to find out?
