We are aware that Colloidal silver can be dangerous.

But Silver Serum contains Microsilver (tm) and not colloidal silver. It is a very different ingredient.

Microsilver (tm) is a patented cosmetic ingredient formulated and certified for use on the skin in order to promote the growth of good skin bacteria and limit the growth of bad skin bacteria.
Our Silver Serum is completely safe and a completely different product class from the colloidal silver you may have read about.
