How to Use Hand Sanitizer, and Some Helpful Hacks
The 20-second rule for hand-washing does not apply to alcohol-based hand sanitizers, which may require at least 10 seconds longer to fully evaporate. Apply the product to one hand and rub it across all hand surfaces, including thumbs, between the fingers, the tops of hands, and the palms, until they are dry. Note that alcohol-based hand sanitizers don’t work when hands are extremely soiled or greasy, and whether it's your DIY product or a commercial one, avoid applying it if you have cuts or open sores on either hand.
Aside from these tips, hand hygiene comes with its own set of risks, says Carrie Kovarik, MD, an associate professor of dermatology at the University of Pennsylvania’s Perelman School of Medicine in Philadelphia. Although it’s essential to keep hands clean, too much of a good thing can break down the skin’s protective barrier, leading to dry, itchy, cracked, irritated skin, and even small breaks (called fissures) that allow germs to enter.
This is especially important for people with conditions like eczema, who are prone to flares. Dr. Kovarik recommends using a mineral oil– or petroleum-based moisturizer immediately after hand-washing or sanitizing, and keeping a small container on hand when going out.
She says that people with any skin condition definitely want to avoid adding essential oils to their DIY recipes, as should anyone who is allergic to certain perfumes or other additives. Finally, Kovarik underscores that people should not be using household-cleaning-grade or baby wipes to clean their hands, as these products introduce harsh chemical irritants.
