Face yoga is a series of repetitive facial exercises that work by stimulating face muscles, tightening the skin and reducing signs of aging. By strengthening the muscles and engaging them in resistance training. There is evidence that shows that face yoga can work for anti-aging. A study conducted by Northwestern Medicine showed that a 30-minute daily facial exercise maintained for over 20 weeks could make middle-aged women look up to three years younger. The participants reported measurably fuller cheeks and firmer skin.
