Wrinkles are created along time by the repetition of a movement on the skin by some muscles of the face, as for example happens when frowning, if the movement is repeated frequently. So the way of preventing it is by avoid moving the muscles and the skin, or in other words, to avoid moving the muscles that will move the skin.
One of the best, if not the best, treatment options for the prevention and treatment of wrinkles produced by the combined effect of sun-damage and the normal ageing process, is to inhibit the transmission of the nerve signal to the muscles that create the wrinkles, with the intention of creating a temporary and reversible inhibition of the contraction, as mentioned above.
It works by blocking the transmission between the nerves and the muscles, and as a consequence, the muscles will not be able to move for a certain period of time. It is a reversible effect.
The blocking effect will last around 4 to 6 months usually, but in some cases it might last for a bit longer. There are no fixed rules on this, as personal variations will intervene.
The treatment is just a number of minimal injections on the area to be treated, and in the right hands, this procedure is almost painless.
Without doubt, the main reason to have the treatment done is to prevent the wrinkles, either to appear at all, or to go further.
In the best case, the aim will be to prevent or avoid the wrinkles to appear, but if the wrinkles are already visible, then the aim will be to avoid those wrinkles to be more visible and prominent (avoid them going deeper into the skin), and eventually to make the wrinkles less noticeable.
This will tend to happen from the repetition
of the treatment
at the right moments.
