How Botox works is that it temporally prevents a muscle from moving. If you cannot move a particular muscle you cannot make the expression that causes a certain wrinkle. It usually takes four to seven days for Botox to start working and the effects tend to last from three to four months. As muscle action gradually returns, the lines and wrinkles begin to re-appear and wrinkles need to be re-treated. The lines and wrinkles often appear less severe with time because the muscles are being trained to relax. As we get older and lose elasticity in the skin, a permanent crease can form leaving a wrinkle that is noticeable even without muscle contraction. Botox does not get rid of these wrinkles, but may help soften them.
When I spotted Frownies on Pinterest I had to check them out. . They are essentially thick pieces of paper with an old school stamp-like adhesive. You wet them, and then stick them on your face in areas you have a wrinkle caused by movement. In the picture, you can see the woman has them in between her eyebrows and on her forehead – typical places you get wrinkles due to making normal facial expressions. Frownies are not moisturizers and they don’t help to fill in wrinkles, nor do they stimulate collagen. They simply prevent you from making the expressions that cause certain wrinkles – exactly like Botox. The advantage to Botox is that it lasts 24 hours a day where you may only wear frownies for about 8 hours a day.
Frownies may mildly improve these expression lines but results would only be temporary and lines would return as soon as you start moving that muscle again.
