Natural vs Man-Made
First of all, not all chemicals that are man-made are toxic. However it is a fact that many man-made chemicals are recent and the question is - is there absolutely no side effects, no toxicity? The real answer is "We are not absolutely sure".
It is only in the 2000s that we discovered that some chemical compounds found in makeup, shampoo, skin lotion, nail polish, and other personal care products have been linked in animal studies to male genital birth defects, decreased sperm counts, and altered pregnancy outcomes.
So to be absolutely safe, Go Natural...
