Serving to smooth out or reduce wrinkles or corrugations; having the property of removing folds or ridges.
From de- (remove) + corrugative (causing wrinkles, from Latin corrugare, to wrinkle). The prefix de- means 'to undo' or 'remove,' making this a technical term meaning 'wrinkle-removing.' This term is primarily medical or technical in nature.
This is the kind of technical jargon that teaches us how English constructs specialized vocabulary—by combining common prefixes and roots in logical ways. A dermatologist might use 'decorrugative' to describe a skincare treatment, but it's a word most people encounter only in medical literature, showing how knowledge communities create precise terminology.
