• Investigator reported improvement [2 weeks]: IGA(investigator's global assessment)
• Response to treatment/Hand eczema severity [2 weeks]: Dermatoscopy
• Response to Quality of Life [week 0 and 2]: questionnaire :DLQI(dermatology life quality index)
• Patient Reported Improvement [up to 2 weeks]: VAS(Visual Analog Score for pruritus)
• Response to treatment/Hand eczema severity [2 weeks]: HECSI
• Response to Microbial Colonization rates [2 weeks]: Staphylococcus aureus colonization rates
