Not everything you put on your skin goes in, but some ingredients DO go transdermal. What does “what goes on goes in” mean?
Think about medicated transdermal patches:
“A transdermal patch is a medicated adhesive patch that is placed on the skin to deliver a specific dose of medication through the skin and into the bloodstream.”
The key here is that size matters – molecules that are small enough can pass through skin, including certain ingredients that are commonly used in personal care products, are small enough to enter the bloodstream. So do you know which? It would be great if you could know, right? But you have to have a lot of time to do research, or be a molecular biologist, to know for sure. And if some ingredients are not disclosed you can’t even research like a boss, because you can’t know what’s in there.
Some ingredients carry big concerns, like preservatives and “fragrance”. So at Earth Mama Angel Baby we err on the side of safety, and assume that whatever we are formulating is going to go on, and IN (and into baby’s bloodstream). That’s why every Earth Mama product rates a 1 on the EWG’s Skin Deep toxin database – the lowest rating a product can achieve.
