Institut Katharos Colloidal Silver Spray at 40 parts per million comes in a large 100 ml bottle fitted with a mister for topical use on the skin.

The spray format covers an area of skin without touching it by hand.

What is colloidal silver?

Colloidal silver is a liquid suspension in which extremely fine silver particles are dispersed through high-purity water without fully dissolving in it. The parts-per-million unit (ppm) is the accepted measure for describing the concentration of these suspensions, expressing the mass of silver relative to the mass of the water carrying it.

What colloidal silver spray does for skin

• A quick refreshing step: Colloidal silver spray mists onto skin and leaves a light watery layer that dries without any oily residue.
• A short ingredient list: The product is limited to silver and pure water, with no fragrance or alcohol.
• Support for a sensitive-area routine: The lightness of the formula suits anyone avoiding multi-ingredient preparations.
• A declared concentration: The product states 40 parts per million outright rather than describing its strength vaguely.
• Easy to carry: A 100 ml size with a mister makes use away from home practical.

Ingredient concentration

Institut Katharos Colloidal Silver Spray is built on a concentration of 40 parts per million of colloidal silver in pure water. The smaller the particles, the greater the surface area per unit of mass, and that is the difference between fine and coarse suspensions. Having a declared concentration figure makes comparison between colloidal silver products possible rather than relying on a verbal description.

Which skin type is it for?

• Oily skin that avoids oil-based preparations.
• Normal skin wanting a light water-based step.
• Anyone who prefers products free of fragrance and colorants.
• People looking for a spray applied without touching the skin by hand.

Where it fits in the routine

Colloidal silver spray comes after cleansing and before moisturizer, in the position of the water-based step of the routine. Leave it to dry naturally, then complete the following steps of moisturizing and protection. In a morning routine, sunscreen goes on as the final step.

How to use

Shake the spray before use, then mist onto the intended area from a short distance with eyes closed. Leave it to dry without wiping, and repeat through the day as needed. Test the product first on a small patch of the forearm before applying it more widely on the face.

Frequently asked questions

What does 40 parts per million mean in colloidal silver?

Parts per million is a unit describing the amount of silver relative to the water carrying it, so 40 parts per million means 40 parts of silver for every million parts of solution. This unit is the accepted way to compare colloidal silver products against one another.

Is colloidal silver spray used on the face?

Colloidal silver spray is used topically on the skin while avoiding the eye area and mucous membranes. A patch test on a small area is always advised before wider use.

How should colloidal silver be stored?

Colloidal silver should be kept in a cool, dry place away from direct light, because light affects the stability of the suspension. Keep the product in its original bottle and do not transfer it to a metal container.

Cautions
