What common mistakes damage the hands?

Washing your hands regularly is essential for hygiene, but washing too frequently, especially with harsh detergent soaps, can weaken the skin barrier. With each wash, some of the surface lipids—crucial for maintaining the skin’s hydration—are removed, which increases transepidermal water loss (TEWL). At the same time, the skin pH, which is normally slightly acidic at around 5, tends to rise, disrupting the skin’s enzymatic activity and its antimicrobial defense mechanisms.

These effects are cumulative: the more frequently the skin is washed, the more vulnerable it becomes, promoting the onset of dryness, tightness, irritation, and even microfissures.

These observations were confirmed by a study conducted in 15 volunteers, designed to assess the impact of different washing and drying techniques on the skin. The results show that even simple washing with water increases transepidermal water loss, and that this effect becomes more pronounced after repeated washings. For example, washing with soap followed by towel-drying increased TEWL from 10.1 to 13.1 g/h·m² after only two washes. Even greater increases were observed depending on the drying method, reaching up to 30.1 g/h·m². At the same time, skin pH exceeded 6.0 after two soap washes, indicating impairment of the skin barrier and its protective functions.

The issue is not to reduce hygiene, but to better adapt it in order to avoid damaging the hands.

For example, it is preferable to use gentle cleansers with a physiological pH and to avoid the most aggressive anionic surfactants, such as Sodium Lauryl Sulfate (SLS) or Sodium Laureth Sulfate (SLES), which are known for their strong detergent power and their irritation potential. In contrast, milder surfactants, such as glucosides (decyl glucoside, coco-glucoside) or betaines (coco betaine), are better tolerated. The systematic application of a moisturizing cream after each washing is also a good habit to adopt to restore the hydrolipidic film and compensate for water loss, thereby helping to preserve the integrity of the skin of the hands.

The skin on the hands is naturally low in sebaceous glands, so it produces fewer protective lipids than other areas of the body. This characteristic makes it particularly dependent on external inputs to maintain its hydration and the integrity of its skin barrier. In addition, the hands are constantly exposed to multiple everyday stressors, such as frequent washing, temperature fluctuations, and friction, all of which gradually weaken the stratum corneum. Without proper care, the skin becomes drier, rougher, and less supple, promoting the appearance of wrinkled hands and accentuating fine lines.

Moisturizing your hands is just as important as caring for the skin on your face.

To do this, the ideal approach is to apply a moisturizing cream after each wash, when the skin has just lost some of its protective lipids, in order to quickly restore the hydrolipidic film. Applying it in the evening before bed is also particularly beneficial: because the skin is less exposed to external stressors during the night, the active ingredients can work more effectively. For a moisturizing cream to be effective, it is important that it combines humectants, such as glycerin, emollients, such as ceramides, and film-forming agents, in order to attract water, limit its evaporation, and strengthen cellular cohesion. Without these regular inputs, a vicious cycle sets in, in which dryness weakens the skin, making it even more vulnerable to everyday aggressions.

Exposure to UV rays is one of the main factors responsible for premature skin aging, including on the hands.

Yet this area is often forgotten when applying sunscreen, even though it is exposed to the sun every day. UVA rays, which can penetrate deeply into the skin, generate significant oxidative stress and activate matrix metalloproteinases, enzymes responsible for the breakdown of collagen and elastin. Gradually, the skin loses firmness, wrinkles deepen, and pigment spots appear. This is referred to as photoaging, in the sense that this aging is caused by UV light.

Incorporating sun protection into your daily routine is therefore essential to preserve the appearance of the skin on your hands. Applying a broad-spectrum sunscreen in the morning, with reapplications in case of prolonged exposure (driving, outdoor activities), helps limit UV-induced damage. Some hand creams now include sunscreen filters, making this step easier. Without these precautions, the effects of the sun build up in a silent yet continuous way, significantly accelerating the skin aging of the hands.

Household cleaning products, particularly dishwashing liquids, contain surfactants capable of solubilizing fats… including those that are naturally present on the skin surface. A study conducted in 11 volunteers examined the impact of five detergents diluted to 0.5% on various skin parameters, especially its lipid content. The results show a negative correlation with skin lipid levels (r = –0.53), indicating a removal of sebum by the dishwashing liquid.

The alkaline detergents in dishwashing products deplete the skin’s lipid barrier, making it more vulnerable to dehydration and external aggressions.

Given these effects, it makes sense to wear gloves during household chores to protect your hands. However, not all gloves are equivalent, and their use should be judicious. Latex gloves in particular can trigger skin reactions when worn for prolonged periods. A study conducted among 455 healthcare professionals showed that 45.05% of participants reported skin symptoms related to glove use, such as dryness, irritation, or itching, and that 18% experienced contact urticaria–type reactions. The risk of dermatitis increased significantly in individuals who wore gloves for more than 5 hours per day, highlighting the impact of occlusion and maceration on the skin.

Thus, while gloves are essential when using household cleaning products, it is preferable to choose materials that are less sensitizing, such as nitrile or vinyl, and to limit how long they are worn to the strictly necessary duration. Prolonged use of occlusive gloves indeed promotes perspiration, which can further impair the skin barrier. Once the gloves are removed, applying a moisturizing product helps restore skin lipids and offset the losses induced by these repeated exposures.

Environmental conditions, particularly cold, wind, and dry air, are major factors that weaken the skin of the hands. Cold causes vasoconstriction, reducing the supply of nutrients and oxygen needed for proper skin function, while the decrease in ambient humidity observed in winter increases transepidermal water loss. The skin then becomes drier and rougher, and may develop cracks, redness, or a feeling of discomfort. If the hands are not protected, they can quickly become damaged.

Wearing gloves in winter, or simply when it is cold and/or windy, is a straightforward measure to prevent damage to the hands.
