|Skin Aging||Biological: Botulinum Toxin A||Phase 3|
Ageing is a dynamic and unchangeable process involving all individuals and affecting the several organic systems. This process is expressed through multiple symptoms and signs, the wrinkles and flaccidity being the most common and visible ones.
In both developed and emerging countries, the interest in skin ageing is, to a greater extent, the result of the progressive increase in the absolute number and the proportion of people experiencing the ageing process in the last century. The psychosocial, as well as the physiological effects of the skin ageing raised a huge demand for a better understanding of this process and, in particular, of the effective interventions.
The use of the botulinum toxin type-A (BTX/A) for aesthetic indication emerged as a result of the clinical observation of those patients treated for facial different dystonia and who presented additional improvement of their expression lines.
The expression lines are most easily noted on the upper third of the face, where surgical treatments are fully invasive and show lesser noticeable results. The upper third of the face was targeted for BTX/A treatment and reported in several scientific literature articles as well succeeded.

- Treatment Success [ Time Frame: Baseline (pre-treatment) and Visit 3 (Day 15) ]Success has been defined as the reduction of any grade to a lower grade of expression wrinkles in the visit 3 (day 15) compared to the baseline assessment. The wrinkles will be classified according to the following: absence, mild, moderate, severe.
