Institut Katharos Premium Colloidal Silver is a 40 ppm colloidal silver solution formulated with only two ingredients: ultra-pure water and silver.

The concentration of 40 ppm (parts per million) corresponds to 40 mg of silver per litre of solution. Institut Katharos produces its colloidal silver in France using an electrolysis manufacturing process.

Designed for external cosmetic use, the simple, minimalist formula can be applied directly to the desired area of the skin. The manufacturer positions its colloidal silver as a solution for helping to purify, soothe and care for the skin.

The generous 500 ml format is particularly convenient for regular users and provides an economical refill-size option compared with smaller bottles.

This product is intended for external use only and should not be ingested.
