Atopic dermatitis is a chronic and highly pruritic disease with a high socioeconomic burden, various aggravating factors let the patients be suffered from disease flair. Skin barrier enforcement, infection control and anti-inflammatory agents are the basics of atopic dermatitis treatment. Increased skin surface pH due to abnormal soap usage can induce various negative effects on skin barrier of atopic dermatitis patient functions such as intact epidermal permeability barrier, SC integrity/ cohesion and antimicrobial barrier function. In addition to barrier reinforcement using epidermal lipid containing barrier cream to compensate these disrupted skin barrier, less barrier breaking cleanses could help to maintain skin surface optimal pH4.5-5.5. Many educational guideline book for atopic patient`s bathing methods recommend the liquid cleanser or cleansing foam instead of classic bar soap. We compared the effects of cleansing foam and classic soap on the disrupted skin barrier of healthy 20 adult. After barrier disruption using rubbing methods and application of cleansing foam and classic soap on the forearms, the results showed the better barrier recovery at 3hr on the group of cleansing foam as 80% compared to the bar soap as 63.4%. The skin surface pH also more increased in the group of bar soap than cleansing foam. We suggested the evidence based guidelines for atopic dermatitis as using the cleansing foam than classic bar for better barrier recovery and maintenance acidic skin surface to barrier disrupted atopic skin.
