FAQ
Q1. What is the meaning of ppm in colloidal silver?
Ans: PPM stands for Parts Per Million, which measures the concentration of silver particles within the liquid. A 40 PPM concentration means there are 40 milligrams of silver suspended in every liter of ultra-pure water, offering a higher strength for targeted skin application.
Q2. What is colloidal silver used for in cosmetics?
Ans: In skincare and cosmetics, colloidal silver is primarily utilized for its natural cleansing and soothing properties. It helps clean minor skin imperfections, targets acne-prone areas, and calms surface irritations without drying out the skin.
Q3. Can this colloidal silver spray be used on sensitive skin?
Ans: Yes, this formula is highly suitable for sensitive skin because it contains only ultra-pure water and silver. It is entirely free from harsh chemical additives, artificial preservatives, fragrances, and stabilizers that typically trigger skin flare-ups.
Q4. Is this Institut Katharos Colloidal Silver Spray authentic and available in India?
Ans: Yes, Rudra Retails sources this product directly from authorized distributors in the USA to guarantee 100% authenticity. Every bottle is safely imported and shipped directly to consumers across India through our platform.
Q5. Why does this product come in an amber glass bottle?
Ans: The amber glass bottle shields the microscopic silver particles from light exposure, which can cause them to degrade or lose efficacy. Additionally, glass ensures that no harmful microplastics leach into the pure formula over time.
