Moisturization and Skin Hydration Study

Skin moisturization is important for patients with atopic dermatitis, commonly known as eczema. Moisturizing right after bathing is widely accepted as the best method to keep skin hydrated. However, there is conflicting research on the timing of moisturizing. The goal of this clinical study is to evaluate the preference of moisturizing while showering/bathing compared to after towel drying in adolescents aged 12-18 with eczema. The main question it aims to answer are: * Which moisturization technique is preferred: while showering/bathing or after towel drying? * How do these techniques affect investigator-assessed eczema severity, patient-reported itch scores, and objective skin hydration measurements? Researchers will compare applying moisturizer while in the shower/bath to after towel drying and to which technique is preferred among participants and if there are different effects on eczema and skin hydration. Participants will: * Apply moisturizer while showering/bathing for one month and after towel drying for one month. * Complete questionnaires on moisturization technique, skin feel, and itchiness. * Undergo skin hydration measurements using a Corneometer® CM825 device.
