Smooth forehead in 7 days😱 My student is 39 years old who was skeptical about face fitness but did not want to get Botox every 3-4 months. Upon our first meeting, I explained to her that forehead wrinkles are caused by spasmed frontalis and occipitalis muscles. Muscles get shortened, blood flow gets trapped, and skin loses support from underneath and forms wrinkles. The best analogy is Roman curtains. Can you picture it? To relax muscles, and reduce overactive mimic, we need to do face fitness.
