One of the golden rules to holistic skin care is “if you can’t eat it, don’t put it on your skin.” So just as you would carefully select your food, you might also consider doing the same for your skincare products.
The reason for favoring natural skincare is simple: the skin is a rather direct line to the bloodstream. In essence, any substance that comes into contact with the skin is to a degree absorbed into the body. Everything in the external environment that your body is interacting with has to be managed by the skin’s microbiome.
