Today, in the market we can find countless hydroalcoholic gels, but not all are the same. A dermatologist has a very simple trick to know which ones to use and which ones not.

Together with the use of the mask, frequent hand washing and the application of hydroalcoholic gel to disinfect the hands have proven to be effective hygiene measures to fight against the advance of the coronavirus.

Although before the state of alarm was declared in Spain, disinfectant gels for hands were in short supply on supermarket shelves and in pharmacies, currently we do not have this problem: this product is abundant and in the market we can find infinite alternatives brands.

The problem is that not all hydroalcoholic gels are the same. Some are more recommended than others, and there is a very simple trick that allows you to quickly identify which gels are best to avoid. Although it may be surprising, for this you do not need to know the composition of the product: you just have to pay attention to its smell.

In two months they have gone from despising them, to being “highly recommended”. If you are going to wear a mask to go outside, this is what you should know.

Elena de las Heras, a dermatologist at the Ramón y Cajal Hospital in Madrid, has resolved in Cadena Ser some of the most common doubts about the use of these hand disinfectant products.

This doctor explains that the ideal alcohol concentration is 70%, and points out that, to prevent its continued use from damaging the skin, it is important that the gel contains few compounds. Alcohol can be accompanied by glycerol or glycerin to hydrate a little, but under no circumstances should you wear perfumesas otherwise it may cause problems. “If it has a pleasant smell, you better not use it,” says Elena de las Heras.

The dermatologist also highlights that, whenever possible, it is more convenient to wash your hands properly than to use a sanitizing gel. If you have no choice but to resort to a hydroalcoholic solution, remember to apply it by rubbing both hands on one side and the other for 20 to 30 seconds, and then wait 20 more seconds for it to dry.
