Serving to remove or reduce wrinkles; having the property of smoothing out wrinkles.
From erugate plus the adjectival suffix -ory (like 'sensory' from 'sense'), indicating capability or function.
The -ory suffix describes things that *do* something—so 'erugatory' describes substances or processes that remove wrinkles, similar to 'perspiratory' for sweat!
