This study intends to investigate patient satisfaction of treatment with Ointment (W/O emulsion) formulations of Potency Class II topical corticosteroids (TCs) for atopic dermatitis (AD) patients in Japan. Objectives include measuring patient satisfaction, treatment adherence, itchiness, and AD severity scores.

Inclusion Criteria:

• Female and male patients with a diagnosis of atopic dermatitis who are treated with Fatty Ointment Potency Class II (Very strong class) TCs
• Patients who are scheduled to change the formulation of the Potency Class II TC from Fatty Ointment to Ointment (Water in Oil; Water per Oil emulsion) as per investigator's routine treatment practice
• Patients who are aged over 20
• Patients who are able to understand and sign a written informed consent

Exclusion Criteria:

-Patients participating in an investigational program with interventions outside of routine clinical practice

• Patients with any contraindication to TCs
• Patients who are regarded as ineligible by the investigator
• Patients who are pregnant or breastfeeding
• For Period 2 (Spring-Summer), patients enrolled in the Period 1

Patients will be recruited by the investigator who will also be the treating physician. As an observational study, only patients who the investigator plans on switching to the ointment (W/O emulsion) from fatty ointment formulation will be eligible to participate. Patients will be recruited for each seasonal phase and same patients may not necessarily be observed between the two seasonal phases.
