DESCRIPTION: Colloidal silver 20 ppm 500 ml 

Colloidal silver is a natural cosmetic product that perfectly cleans and regenerates the skin. It reduces sebum secretion and has a beneficial effect on acne, enlarged pores, skin mold, inflammation, and so on. Soothes irritated or reddened skin. With regular use, it regenerates the skin and has beneficial effects.
Colloidal silver at a concentration of 10 ppm holds transparent (clear) color. Exceptions are stronger concentrations above 40 ppm, which can agglomerate over time (particle aggregation occurs), which results in a slight collision of colloid, but this is not a defect.
The concentration of the solution is given in ppm (parts per million). 10 ppm indicates the concentration of 10 Ag particles in 999,990 water H2O particles (10 mg of silver in 1 liter of solution).
Purchased Colloidal silver not recommended to dilute! Not the ratio of 1 part of colloidal silver: 1 part water = 1/2 of the original concentration! In addition, the solution can be degraded by impurities which are common in ordinary but also in distilled water and can not be removed in domestic conditions in any way.

Colloidal silver is available in these variations of concentrations: 5, 10, 15, 20, 30, 40 and 50 ppm.
