INTRODUCTION: Atopic dermatitis (AD) is characterized by impaired epidermal barrier with increased transepidermal water loss (TEWL). Scratching further compromises skin integrity, contributing to a cycle of inflammation. The objective of the present study was to investigate a topical anti-itch foam in improving skin barrier and itch.
MATERIAL AND METHODS: A single center open study was performed on 26 adults previously diagnosed with AD but without active lesions. One leg was treated with a single application of an anti-itch foam. Dryness, scaling, roughness, cracking, and signs of scratching were assessed before, 6, and 24 hours after application. Skin hydration was measured at 24 hours. The same product was applied twice daily for 7.5 days to the other leg, and skin hydration and TEWL were measured at baseline and on days 2, 8, and 10. Pruritus was assessed by volunteers and by a dermatologist.
RESULTS: A significant increase in skin moisture (P less than 0.001) was measured 6 hours after a single application. Scores of dryness, scaling, roughness (P less than 0.001) and cracking (P=0.002) were significantly improved up to 24 hours after a single application. After a 7.5-day repeated application period, the anti-itch foam significantly reduced TEWL (P less than 0.001) compared to baseline. Skin hydration significantly improved (P less than 0.001) in the same time period. 48 hours after the last application, these improvements remained significant (P less than 0.001).
CONCLUSIONS: The anti-itch foam improved the skin barrier. It provided immediate relief of clinical signs of AD including pruritus. Moreover, it delivered a long-lasting moisturizing effect, comforting the skin, and improving overall skin condition. J Drugs Dermatol. 2016;15(suppl 11):s77-80..
