Dr Rhazes Ultra Protect Gel is a result of extensive scientific research backed by state-of-the-art technology. While ordinary hand-sanitizers need to be applied repeatedly on touching any new surfaces, this gel disinfects and protects even after being in contact with infected surfaces or hands, non-stop for 2 hours. It kills 99.9% viruses & bacteria with a proprietary mix of anti-microbial ingredients along with 70% ethanol that works on surfaces too. The lemon extracts give it a pleasant fragrance and keep your hands clean and fresh smelling.
