Overview
Brief Summary
Hand washing and the use of hand sanitizers are important interventions in disease prevention. Engaging in frequent hand washing is especially effective in preventing the spread of viruses, as this removes microbes and prevents the spread to others. Hand dermatitis, however, is a common occurrence in certain occupations, such as healthcare workers. With the onset of the SARS-CoV2 (COVID-19) pandemic, hand hygiene measures are further enforced as there is no cure or vaccine for this virus.
In the study, the effects of hand washing and the use of hand sanitizer on skin proteins and lipids will be assessed.
Detailed Description
Hand washing and the use of hand sanitizers are important interventions in disease prevention. Engaging in frequent hand washing is especially effective in preventing the spread of viruses, as this removes microbes and prevents the spread to others. Hand dermatitis, however, is a common occurrence in certain occupations, such as healthcare workers. With the onset of the SARS-CoV2 (COVID-19) pandemic, hand hygiene measures are further enforced as there is no cure or vaccine for this virus. The stratum corneum is in the outer layer of the epidermis, and it contains several proteins and lipids that are important for skin health. This skin layer can be disrupted by agents that cause skin dryness and irritation, resulting in a dysfunctional skin barrier when there is loss of filaggrin breakdown products, also referred to as natural moisturizing factor (NMF), and lipids. This then leads to the unwanted dermatologic effects of skin dermatitis, and in some patients, contact dermatitis. While it is known that frequent hand washing and hand sanitizer use causes hand dermatitis, the effects on skin barrier proteins and lipids has not been studied. In this study, the effects of hand washing and the use of hand sanitizer on epidermal proteins and lipids will be assessed. The skin barrier will be examined with skin tape strips (STS) and transepidermal water loss (TEWL) before and after topical skin exposure to hand sanitizer use and hand washing. Questionnaires will be administered to inquire about allergy history, frequency of hand washing, and use of detergents and soaps.

Outcomes
Primary Outcomes
Measure the change in transepidermal water loss and skin components after using hand sanitizer.
Time Frame: Through study completion, up to 1 year
Skin barrier assessments at baseline, then after hand sanitizer use will be performed. Analysis of skin filaggrin breakdown products, lipid profiles, and transepidermal water loss will be compared.
Measure the change in transepidermal water loss and skin components after hand washing with soap and water.
Time Frame: Through study completion, up to 1 year
Skin barrier assessments after hand washing with soap and water will be performed. Analysis of skin filaggrin breakdown products, lipid profiles, and transepidermal water loss will be compared.
Secondary Outcomes
- Individual reporting of hand dryness and environmental exposures(Through study completion, up to 1 year)
