Treatment of expression lines
Factors such as the passage of time, stress, sun, environmental pollutants accentuate wrinkles on the face, whether static, that is, those that do not change with gestures and remain at all times; or dynamic, they occur when the muscle contracts and the skin that accompanies it too.
Produces a micro-relaxation of the muscle, which also causes the skin to relax and during the time the muscle is relaxed, the expression lines disappear.
