The hands are among the most exposed areas of the body and are constantly in use in everyday life. Frequent washing, the use of alcohol-based hand rubs, contact with detergents, and climatic variations (cold, wind, sun) progressively weaken the skin barrier. Moreover, the skin of the hands is relatively thin and poor in sebaceous glands, which makes it vulnerable to dehydration. Alteration of its hydrolipidic film, the aqueous-lipid mantle that covers it, may result in tightness, a feeling of discomfort, or even the appearance of cracks or irritation.
Furthermore, the hands are often one of the first areas to reveal the signs of skin ageing. The progressive reduction of lipids, collagen and elastin, combined with repeated exposure to UV radiation, can promote the development of pigmentation spots, a loss of firmness, and a more pronounced appearance of the veins and tendons. It should be recalled that exposure to the sun is one of the main factors responsible for the appearance of signs of ageing, both on the face and on the hands.
Including a hand cream in one’s skincare routine helps to support the barrier function and hydration of the skin, thereby contributing to the maintenance of its comfort and appearance.
The benefits of a hand cream were demonstrated in a study conducted with 25 volunteers subjected to repeated handwashing (four times a day for two weeks with a neutral soap). Without application of cream, skin roughness gradually increased, with the index rising from 100 to 108.5 by day 9, while hydration decreased from 79 to 65.5 after 14 days. In contrast, when participants applied a cream after each wash, roughness decreased (to 94.5 from day 2 and 94.8 on day 14) and hydration stabilised at around 75.6 after a slight initial drop. The cream used contained, in particular, glycerine, oils acting as occlusive agents, as well as emollients such as glyceryl oleate, illustrating the value of a formulation that combines several types of active ingredients.
These results show that the systematic application of a cream after washing makes it possible to significantly limit the dryness and roughness induced by repeated irritation.
