This is an open-label, randomised, comparative, prospective, interventional study of a cosmetic product.
Atopic dermatitis is a common chronic inflammatory skin condition that affects individuals with specific alterations to the epidermal barrier. It is also characterised by defective ceramide production. Emollients play an important role in managing atopic dermatitis, including during the maintenance phase following topical cortisone therapy. However, the effect of CeraVe emollient cream on restoring skin barrier hydration has yet to be investigated. The primary objective is to evaluate the effect of the CeraVe emollient on restoring skin barrier hydration as a maintenance regimen in subjects with mild to moderate atopic dermatitis. The secondary objectives are to evaluate and compare the cosmetic acceptability of CeraVe with that of a commonly used emollient produced in a licensed pharmacy laboratory, and to assess the differences in ADCT (Atopic Dermatitis Control Tool) scores between groups. Subjects with mild-to-moderate atopic dermatitis (AD), as defined by an EASI score of 1-21, will be enrolled in the study. Only individuals with an EASI score reduction of at least 90% between screening (Day -15) and Visit 1 (Day 1) will be randomised into two groups. Group 1 will enter the maintenance phase with CeraVe emollient, while group 2 will be treated with a standard emollient. Both groups will be provided with a basic detergent for washing. If the participant experiences a relapse of atopic dermatitis (AD), as reported in their diary and in the eCRF, they should discontinue the application of CeraVe Emollient or a common soft emollient. The subject should be examined by a physician and treated according to the severity of the AD. In this case, they will be withdrawn from the study.

During the 42-day maintenance phase, subjects must apply the CeraVe emollient twice a day after washing with the basic detergent as part of their normal hygiene routine.

RECRUITINGChanges in EASI score
Changes in EASI (Eczema Area and Severity Index) score. A clinical assessment of disease severity (EASI) will be conducted at three separate visits: a screening visit on Day -15, and two visits on Days 1 and 42. At the screening visit, subjects will be given a medical corticosteroid topical treatment (mometasone furoate cream) to improve their EASI score by at least 90% between Day -15 and Day 1. Only individuals with an EASI score reduction of at least 90% between Day -15 and Day 1 will be randomised into two groups. EASI score interpretation: 0: clear; 0.1-1: almost clear; 1.1-7: mild; 7.1-21: moderate; 21.1-50: severe; 50.1-72: very severe.
Time frame: From enrollment to the end of treatment at 6 weeks
Cosmetic acceptability
The cosmetic acceptability of the emollients is assessed in two groups of participants using specific questionnaires. The 21 questions covered texture, fluidity and penetration of the emollients. Scoring was as follows: 0 = totally agree; 1 = agree; 2 = disagree; 3 = totally disagree.
Time frame: From visit 1 to the end of treatment at 6 weeks
Changes in ADCT score
The ADCT (Atopic Dermatitis Control Tool) score is compared between groups. This is a set of six concise questions designed to evaluate the various aspects of atopic dermatitis (AD) control that have been identified as important by patients and clinicians. Each question is scored between 0 and 4 points (0 = none, 4 = very severe). The sum of the points from the answers to the six ADCT questions is the ADCT total score. The ADCT total score will be between 0 and 24.
Time frame: From enrollment to the end of treatment at 6 weeks
The number and proportion of subjects who experience a relapse of AD.
The number and proportion of subjects who experience a relapse of atopic dermatitis (AD) in the two groups. If a relapse of AD occurs, the subject should discontinue the application of the CeraVe emollient or the common soft emollient. They should be examined by a physician and treated according to the severity of the AD. In this case, they will be withdrawn from the study.

Time frame: From enrollment to the end of treatment at 6 weeks
Changes in the visual appearance of the skin barrier over time, as observed by comparing images collected during the three scheduled study visits.
We will compare images of visual changes to the skin barrier collected at screening and visits 1 and 42. The images will only refer to areas affected by the disease and will not contain any recognisable features that could identify the subjects.
Time frame: From enrollment to the end of treatment at 6 weeks
