Many customers prefer to use products with natural ingredients only, and without harmful chemicals. But this is when it gets confusing: scientifically, the biological effect of a particular chemical is the same, whether it is synthesized in a lab or isolated from natural sources in a lab.
Beyond that, there is no direct correlation between the benefits & dangers of a chemical and whether it has been "manmade" or naturally found.
It is important to distinguish between a chemical that is "synthetic" but structurally identical to a natural one, and a synthetic one that is not found in nature.
The bottom line is that any ingredient needs to be proven safe and effective in its intended quantity by research.
To ease your mind, every ingredient we used is in that category! Naturally derived or structurally identical, and safe for use.
