Abstract

Background: The prevalence of allergies increases worldwide. Allergies may increase the risk of skin reactions.

Objective: To evaluate the prevalence of allergies and skin reactions in the adult population, the strength of their relationship, and their impact on the quality of life.

Methods: An online survey was conducted in a representative population of 11,067 adults from China, USA, Brazil, Russia, and France.

Results: Overall, 35.6% of respondents reported having allergies, they were predominantly fair-skinned women, and younger than responders reporting no allergy. Among patients reporting allergies, 68.6% declared that their allergy makes their skin reacts. A strong association between allergy and major skin reactions was observed, which were associated with skin discomforts such as itching, burning, and pain. Skin discomforts were associated with an increased risk of quality of life alteration.

Conclusions: Quantifying the prevalence and the association of allergies with skin reactions and discomfort sensations is critical to evaluating the impact on quality of life. Since skin barrier alteration is hypothesized as a risk factor and a route of sensitization for allergy development, the daily use of topical treatments, such as moisturizers, could help prevent allergic skin reactions, discomfort and impaired quality of life in individuals with an altered skin barrier.

Keywords: allergies; moisturizers; quality of life; skin barrier dysfunction; skin manifestations.
