This study aimed to investigate the levels of skin moisture and sebum in children with a house dust allergy without skin symptoms. This was a case-control study involving children, aged 0-18 years, who were being followed up for an allergic airway disease in a pediatric allergy clinic. Age, gender, hemogram parameters, and IgE values were evaluated. The skin moisture and sebum percentages of the patients and control group were measured by a non-invasive bioimpedance method using a portable digital skin moisture and sebum measurement device on the cubital fossa. The median value of the skin moisture percentage in the house dust mite allergy-positive patient group was significantly lower than that in the house dust mite allergy-negative patients and the control group (p < 0.001). The house dust mite allergy-positive patient group had the lowest skin sebum content. However, there was no statistical significance among the groups in terms of skin sebum percentage (p = 0.102). In the study, children with a house dust allergy were found to have lower levels of skin moisture and sebum. The regular use of moisturizers for children with a house dust allergy should be kept in mind as an effective solution to protect the skin barrier and reduce skin symptoms.
