BACKGROUND: Diaper dermatitis (DD) is the most common acute inflammatory skin disease. It has a serious effect on children's and families' quality of life. We aimed to screen and evaluate the efficacy of different formulas for relieving the diaper dermatitis symptoms by developing a kind of diaper dermatitis-like reconstructed human skin equivalent in vitro.
MATERIALS AND METHOD: We developed the human skin equivalent for diaper dermatitis with 0.2% Sodium lauryl sulfate (SLS). The diaper dermatitis-like human skin equivalent was characterized by high level of inflammation, such as overexpression of interleukin-1α (IL-1α), and impaired skin barrier. Four formulas with potential of anti-inflammation and promotion of skin barrier function were topically applied on the diaper dermatitis-like human skin equivalent surface. The afterward protection efficacy was evaluated by endpoints of IL-1α, tissue viability, and skin barrier function.
RESULTS: The chemical irritant induced high release of IL-1α, impaired tissue viability, and skin barrier function. The cream prepared with potential of anti-inflammation and skin protection could effectively decrease and relive the impact of irritant with decreased level of IL-1α and the higher tissue viability than the placebo exposure.
CONCLUSION: The results showed that diaper dermatitis-like human skin equivalent induced by SLS can mimic the skin irritation response of the diaper rash.
