Background: Ultraviolet Irradiation has been shown to elicit alterations in corneocyte adhesion. Purpose: To evaluate the early events in the changes of physical properties of the stratum corneum following a single ultraviolet B (UVB) irradiation. Method: Squamometry (Chroma C* of D‐Squames) was used in 40 volunteers to assess the variations in stratum corneum cohesion during 3 consecutive days following 1.5 MED UVB irradiation on the forearms. Results: Subjects with normal or moderately dry skin showed a significant increase in squamometry values during the 24 or 48 h following irradiation. Subjects with severe xerosis showed a progressive decrease in that value over time. Conclusions: UV‐Squamometry is a convenient, rapid and sensitive method for evaluating the direct effect of UVB radiation on the stratum corneum.
