Wearing the lips-shaped mouthpiece helps to exercise 12 facial expression muscles and turn back the clock, its makers claim.
The user has to wear the 'Face Slimmer' on their mouth, and spend three minutes each day repeating vowel sounds, the 'New York Daily News' reported.
This would "give sagging facial skin and muscles that much-needed daily lift," manufacturers said.
"The movements are given extra load by the mold, forcing everything to work a bit harder and resulting in more youthful, vibrant faces," they said.
The product is priced at USD 61.
