After 4 months of using these products, several side effects have been reported, especially for health workers.

Sir,
Since Pandemic COVID-19 began, disinfecting and hands washing with soap or alcohol-based hand rubs (ABHRs) have been among the most economical, easiest, and essential measures to prevent the virus spread. Both methods, hand washing or the use of ABHRS, have proven their effectiveness on SARS-CoV-2 ( severe acute respiratory syndrome coronavirus 2). After 4 months of using these products, several side effects have been reported, especially for health workers. In this article, we will try to deduce some recommendations for hand hygiene (Table 1), useful especially as summer begins.

SOAP
Over the years, handwashing with soap and water has been considered a measure of personal hygiene; and now, it became a ritual to avoid contamination during the COVID-19 pandemic.
Soap works by dissolving the lipid membranes of microbes, then making them inactive. It has been demonstrated that water containing 1.00% powdered is useful in removing viruses and deactivates their envelope, including coronavirus .
The soap must be obtained from a liquid dispenser; the bar form is not recommended since it may contain germs. However, other studies have shown that the risk of transmitting microorganisms by washing hands with previously used bar soap is negligible (1).

ALCOHOL-BASED HAND RINSES (ABHRS)
According to WHO, the (ABHR) preparation must contain (2) A recent study has confirmed the effectiveness of these WHO-recommended formulations on Sars-CoV-2 (3).
Three formats of the ABHR are recognized (gel, liquid, or foam); some studies have tried to compare their effectiveness and their virucidal action. It has been suggested that, for the adequate dose, the liquid form is much more acceptable since it is faster to dry and gives a less sticky feeling. The gel seemed to be more moisturizing. The foam format combined the two proprieties (4).
There is no precise volume of application; it varies between 1.5 and 3ml, which is equivalent to one pump from the foam bottle. Nevertheless, the quantity that is recommended by The World Health Organization is one that can cover all surfaces of the hand (2).

Summer season begins, and some dermatologists reported that the sun exposure after the application of(ABHRs) could cause burns or irritation. Still, the components of (ABHRs) are not photo-sensitizing; a study (5) realized to compare the local tolerance of alcohols commonly used an alcohol-based hand rubs for hand hygiene (ethanol, propanol) have confirmed this fact.
Hand washing after ABHRs application is not recommended, water is capable of removing superficial sebum layer as well as eliminating the emollients associated with ABHRs for hydration.

Consent
The examination of the patient was conducted according to the principles of the Declaration of Helsinki. -Use a moisturizer after each wash or as many times as possible during the day. -Apply ABHRs on dry skin. -Prefer the gel form rather than liquid. -Apply ABHRs for 30s and with an amount that covers the palms of the hands -Apply alcohol more often in summer than handwashing since it is less drying and not phototoxic. -There is less contact with a contaminated object or surface at the beach; hand disinfection should be less, prefer alcohol or individual bar soap.
