unwrinkled

The word unwrinkled paints a picture of smoothness. At its most literal, it describes something that does not have wrinkles, creases, folds, or lines on its surface. Think of an unwrinkled bedsheet pulled tight over a mattress, a page that has stayed flat, or the smooth skin of a young face. It often suggests that something looks neat, fresh, or well kept. "The explorer carefully unfolded the unwrinkled map, eager to chart his course."

However, unwrinkled is not limited to physical objects. In literary or expressive writing, it can also describe a face, brow, or expression to suggest calmness and a lack of worry. An unwrinkled brow, for example, gives the image of someone peaceful and untroubled. This use is less common than the physical one, but it is still clear and natural in context.

The power of this word lies in its contrast with "wrinkled." While wrinkles often suggest age, pressure, use, or folding, unwrinkled points to the absence of those marks. It does not always mean perfect, but it usually does mean smooth and even.

So whether you are describing cloth, paper, skin, or, in a more figurative way, a calm expression, unwrinkled suggests a smooth surface or an undisturbed look, free from visible lines and folds.
