Commercial glucocorticoid formulations and skin dryness. Could it be caused by the vehicle?

Eczema craquelé can be induced by repeated open application of a topical glucocorticoid, viz. 0.05% clobetasole 17-propionate cream. This might not be invariably due to the active component. Comparison of the skin surface roughness as assessed by profilometry and as expressed by RZDIN showed a decrease after repeated open application of 0.1% betamethasone 17-valerate cream and 0.25% prednicarbate cream, but an increase following the vehicle of the latter preparation. Thus commercial oil-in-water emulsion preparations seem to be potentially injurious to human skin, though this may be masked when a glucocorticoid is added.
