With the spread of the Coronavirus, the use of hand sanitizer is more important than ever, according to the American Center for Disease Control and Prevention, one of the best ways to prevent the virus is to use a hand sanitizer that contains at least 60% of alcohol. But for how long the hand sanitizer last on your skin?
Hand soap and hand sanitizer may seem interchangeable but are intended for different conditions. While the sanitizer is smart at hand when you’re on the move, healthcare professionals agree that nothing outperforms thorough handwashing with regular water and soap.
The effectiveness of hand sanitizer on skin
The main ingredient in most hand sanitizers is isopropanol (rubbing alcohol) or ethanol (the main ingredient in alcoholic beverages).
Alcohol has a long history as an effective antiseptic against some viruses and bacteria, as long as the solution contains enough alcohol in it.
Hand sanitizer is a practical backup if you don’t have soap and water. But in general, antiseptics are not as effective as hand washing. In addition, hand sanitizers can end and require careful technology and diligence to work properly
How to use Hand sanitizer
Hand sanitizer is a practical backup if you do not have access to soap and running water. But in general, antiseptics are not as effective as hand washing. In addition, hand sanitizers can end and require careful technology and diligence to work properly.
People generally don’t use enough hand sanitizer or spread it around their hands as often as they should. To use a hand sanitizer correctly, apply the specified amount as directed by the product label to the palm of one hand, and rub the cleanser thoroughly on both hands to dry. The CDC recommends that this process, like washing hands, should take 20 seconds.
Hand sanitizer is effective in killing some, but not all, microbes. Here are some germs that can’t protect you:
- Cryptosporidium. Parasitic infection that causes breathing and digestive problems.
- Norovirus. A kind of viral infection that can cause vomiting and diarrhea.
- Clostridium difficile. A type of bacterial infection that can cause bowel disorder and inflammation
How long does a hand sanitizer last on your skin?
Hand sanitizer does not work in the long run, so washing hands with soap and water should be the first choice for everyone.
Although alcohol-based disinfectants are a suitable alternative to soap and water, once you touch another contaminated surface, your hands get dirty again, so, no handwashing or using an antiseptic keeps your hands clean for more than two minutes.
When you finish cleaning your hands in any way, no residue will remain, but you can re-contaminate your hands on foo, by touching another dirty surface.
So, before you decide to eat something or touch your face, you need to clean your hands again, even if you only clean them 10 minutes ago.
While using hand sanitizer, be sure to cover all surfaces of your hands and rub them together until they dry, but when your hands are clearly dirty, disinfectants or gel do not work and soap and water should be used.

To wash your hands properly, wash your hands with soap and rub for at least 20 seconds, and make sure that you put sterile between your fingers and the backs of your hands and under your fingernails by scraping your fingernails with the palm of the other hand. It will prevent coronavirus and it is best to avoid touching your face as much as possible to protect yourself from infection.
What to look for in a good hand sanitizer
Alcohol-based antiseptics must contain at least 60 percent of alcohol. But any concentration between 60 to 95 percent will do work.
The concentration of less than 60 percent of alcohol can reduce bacterial growth, but it will not completely eliminate it. Therefore, beware of hand sanitizers that contain very little alcohol, or hand sanitizers that use alcohol substitutes, which are not effective or recommended by the CDC.
There is no evidence that hand sanitizers are harmful to your health. However, if you use hand sanitizer frequently, alcohol may cause slight skin irritation.
Using a lot of hand sanitizer dries your hands, and it can crack and bleed. If you have a skin condition such as eczema, it may worsen it.
Alcohol-based antiseptics can also cause alcohol poisoning if more than two pairs of the mouth are swallowed, so make sure to store any hand sanitizer out of the reach of children.
