Our skin will absorb everything we put on it, and our body will have to figure out what to do with it. Think of it like this- your body functions best when you fill it with whole foods, which contain the very raw materials our cells need to function. Filling your body with processed foods full of inflammatory oils, sugar, and synthetic ingredients provide no nutritional value, and even burden the body with figuring out how to process (or store) it all. What we put on our skin or breathe in our air is processed the same exact way. It can do so effectively and gracefully, or it can struggle with unknown ingredients.
