Hands irritaded by a regular washing?
Washing hands is a very important barrier gesture, especially during this pandemic period. This gesture can even saves lives as the World Health Organization (WHO) reveals in its program "Clean care is safer care".
However, too frequent hand washing, whether with soap or an alcohol-based product, can cause skin irritations that will manifest by cracks, dry skin or dermatitis (1).
Why is the skin irritated?
The skin is like a “protective glove” that protects our body from external agents and prevents water loss. On the surface of the epidermis and directly in contact with the outside, we have the stratum corneum, a layer composed of dead cells which secretes a waterproofing lipid (2). This stratum corneum with its hydrolipidic film plays a fundamental role since it represents the first barrier against external agents.
By using in excess soap and detergents, we attack the stratum corneum which breaks and makes the skin barrier fragile (3). Other hand hygiene practices also increase the risk of skin irritation, such as (4) :
Regular hand washing with soap and water, immediately before or after the use of alcohol-based product
Putting gloves on wet hands
The use of hot water for hand washing
The practice of hand hygiene outside the scope of the indications
The use of gloves outside the scope of the indications
What can we do against these irritations?
In order to prevent the development of skin lesions, the hand hygiene practices mentioned above should be avoided. However, not all risk factors for irritation can be removed since a regular hand washing is necessary, especially during this pandemic period. Then, it is recommended to regularly apply a protective hand cream or ointment (4). But how to choose it?
When the skin is irritated, the main challenge is to repair the stratum corneum. For this, vitamin A is decisive. Also called retinol or retinoid derivative, this vitamin is a lipophilic molecule that has the ability to get through cells membranes. Once inside the cells, it will bind to specific receptors and stimulate gene expression, which results in cells proliferations and differentiations.
In other words, applying a vitamin A-based cream or ointment on an irritated skin will allow the multiplication of cells and therefore the regeneration of the skin. Retinol will help the compacting of the stratum corneum and the thickening of stratum granulosum.
In conclusion, a vitamin A-based cream or ointment will have a repairing and protective effect on your hands damaged by too frequent wishing (5).
In case of skin irritation, PHARMA développement manufactures and commercializes
vitamin A-based products.
