10. Heavy Brow
Some people report that injections of Botox into their forehead leave their brow feeling heavy. This occurs because the muscle in the forehead has been weakened to reduce wrinkles and thus has to work harder to keep the brow lifted. The muscle will fatigue easier and your brow will feel heavier.
Botox has its uses, even in cosmetics, but do you really want to put a neurotoxin into your body just to erase a few fine lines and wrinkles? Given that the effects are marginal at best, why not look to other methods of reducing the signs of aging? Aging gracefully is becoming ever more popular as people reject the obsession with appearance that has made Botox into a billion dollar industry.
