Hydroalcoholic product: the consequences on our hands.

For the product to be effective, it is necessary to adopt the correct techniques to use it properly. First rule : Always apply your antiseptic solution to dry, unbroken, undamaged hands without visible dirt. Indeed, if you apply it to wet hands, the product will be diluted and its effectiveness reduced. Similarly, the alcohol contained in the solution is deactivated by the presence of too much oil on the skin. Therefore, apply a sufficient dose of lotion in the palm of your hand (about 3 mL). Then rub vigorously for at least 30 seconds until the hydroalcoholic solution has completely evaporated (dry hands) and the emollient has fully penetrated (non-sticky hands). Remember to thoroughly rub the back and palms of your hands, the tips of your fingers, under the nails, the spaces between your fingers, as well as your wrists. Remember : The hydroalcoholic product has been designed solely for hand disinfection. Therefore, it is advisable to avoid any contact with the mucous membranes.

Hand sanitiser gel is capable of eliminating most germs. However, in the process, the alcohol also disrupts the skin's natural hydrolipidic film, leading to dryness, cracks, irritation, tightness, and vulnerability to external aggressions. Daily and frequent use of hand sanitiser gel can also alter the microbiome present on the skin's surface. Indeed, when we use the sanitising solution, we not only destroy the pathogenic organisms of the transient flora that can cause serious diseases, but we also reduce the resident flora of the epidermis which contributes to our immune defences. But don't panic, it quickly reforms. However, the same observation is made with soap. Moreover, intensive and excessive use of hand sanitiser gel, like with soap, can cause eczema and atopic dermatitis, weakening the epidermis and exposing it to exogenous infectious agents.

Hand sanitisers prove to be indispensable in high-risk situations, for instance during an epidemic. However, intensive and frequent use can cause discomfort to the skin. Much like soap, the hand sanitiser will remove the skin's hydrolipidic film and destroy the resident flora, both of which are responsible for protecting the skin from external aggressions. To minimise damage and maintain the epidermis, opt for a hand sanitiser concentrated in emollient active ingredients (glycerine, aloe vera, etc...) and above all, remember to consistently hydrate your hands daily with a dab of nourishing care.
