Abstract
Prolonged contact with EVA suit materials causes a spectrum of dermatological conditions in frequent EVA workers. Pressure-point dermatitis, contact sensitization, and regolith particle microtrauma combine to create a distinct clinical syndrome. We describe 89 cases and evaluate mitigation strategies.
EVA suit dermatitis represents a convergence of physical and chemical irritant mechanisms. The inner suit liner creates prolonged pressure contact at predictable anatomical sites. Sweat and suit material interaction creates a chemical irritant environment. And despite decontamination protocols, microscopic regolith particles persist on suit inner surfaces and act as mechanical irritants.
We retrospectively analyzed 89 cases presenting to Aristarchus Plateau Clinic over 36 months. Pressure dermatitis at shoulder and hip contact points was most common (58%). Contact dermatitis from suit polymer off-gassing affected 21 cases. Regolith microtrauma presented as a distinctive distribution of folliculitis-like lesions in 10 cases.
Mitigation strategies with demonstrated efficacy: moisture-wicking liner replacements (reduces pressure dermatitis incidence by 40%), barrier cream applied at pressure points before EVA, and suit liner laundering every 3 EVA cycles rather than weekly.
A practical note for field conditions: the multi-function EVA kit towel (standard issue) serves as an effective post-EVA skin assessment tool — residual regolith on skin is visible against white towel fibers and should prompt additional decontamination before suit removal.
