## 4 Discussion  
In this work, it was tested whether aesthetic speech therapy was efficient in correcting facial wrinkles. Supporting statistical analysis indicates that there was no significant change in the zygomatic muscles. Instead, it shows that there was a clear volumetric reduction in the period area. In the period area, there was then a significant tissue distension due to these exercises. However, from this comparison, the authors' opinion is that there is also a minimum of volumetric increase in the zygomatic area, as reported in other studies [29]. For sure, in the period area, there clearly was a decrease in tissue volume, mainly in the orbiculars muscle of the mouth. The time variable was not found to be significant. Also, [PERSON] et al. [30] reviewed the literature and reported that authors do not agree about the duration of the therapy. They reported that to achieve good outcomes from logopedics aesthetic procedures, the duration and frequency of treatments required differed. However, we believe that participant compliance, motivation, and consistency are important for treatment efficacy. The constant practice of the exercises over time is crucial for the emergence of results. It could be speculated that changes could have occurred in the muscle tissue, considering that a protocol of targeted exercises was performed for three consecutive months. However, it cannot be ruled out that the changes could also have occurred in other tissue layers, such as fat. As can be deduced from the responses to the self-assessment questionnaire, although the change in zygomatic muscles was not statistically significant, the participants improved their perception of their appearance. This may be because the aesthetic evaluation of the face is complex, subjective, and influenced not only by physical aspects, but also by social and psychological factors, since the concept of beauty is something properly subjective [31]. Aesthetics are important in interactions between people and in self-image judgment, which is linked to self-esteem. Therefore, it is very important to assess how individuals see their faces and the expectations related to their face image [32]. In this study, many women increased their satisfaction after treatment, which is a good way to evaluate the effectiveness of aesthetic speech therapy treatment. \begin{table}

Table 2: Questionnaire responses before and after the treatment, with the differences expressed as percentages. Several other studies have also shown the effectiveness of aesthetic speech therapy. The studies by [PERSON] et al. [23] and [PERSON] et al. [33] showed that all participants undergoing aesthetic speech therapy perceived changes in the reduction of wrinkles around the eyes and lips and at the level of the nasolabial fold. In addition, participants have also reported tighter and brighter skin. Through photographic documentation, [PERSON] and [PERSON] [20] analyze three participants experiencing aesthetic speech therapy.
