The people who form the intervention groups will receive a facial cosmetic of natural components to be administered for 28 days, for which they will be given the cream.

The cream will be provided to the participants on the 1st day of the talk. The container containing the facial cosmetic will be applied twice a day, morning and evening.

Afterwards, in the "experimental" group, the participants will be given a talk on how to administer it according to the "positive reinforcement" method.

The people who form the intervention groups will receive a facial cosmetic of natural components to be administered for 28 days, for which they will be given the cream.

The cream will be provided to the participants on the 1st day of the talk. The container containing the facial cosmetic will be applied twice a day, morning and evening.

This group will continue to use their usual cosmetics and complete the questionnaire on the first day of the study and on the last day of the study (28 days later).

A 30-minute talk based on mindfulness, positive thinking and teaching for the application of the cosmetic through positive messages (Ayuna method).

The Rosenberg self-esteem scale is a test with good psychometric properties, and is one of the most widely used tests for the evaluation of self-esteem in clinical practice and scientific research. The Rosenberg Self-Esteem Scale (RSES) is made up of 10 items that refer to self-respect and self-acceptance rated on a 4-point Likert-type scale, ranging from 1 (totally disagree) to 4 (totally agree). Items 1, 3, 4, 7, and 10 are positively worded, and items 2, 5, 6, 8, and 9 negatively. Each dimension is made up of 6 items that are rated on a 99-point scale ranging from 1 (totally disagree with the item) to 99 (totally agree with the item). The higher the score, the higher the self-esteem.

The "Perceived Stress Scale" (PSS), constructed in its original version, has been the instrument most frequently used to study the relationship between stress and psychological health, The questions refer to feelings and thoughts during the last month. In each case, respondents are asked how often they felt a certain way on a five-point scale ranging from 0 'never' to 4 'very often'.

To calculate a total PSS score, the responses to the four positively stated items (items 4, 5, 7, and 8) must first be reversed (i.e., 0 => 4; 1 => 3; 2 => 2; 3 => 1 ; 4 => 0).

Then the PSS score is obtained by adding all the elements. Higher scores indicate higher levels of perceived stress.

The Short Mood Introspection Scale. The scale consists of 16 adjectives that measure the mood of the current moment. Participants rate themselves on a four-point response scale (1 does not describe my mood at all, 2 describes my mood a little, 3 describes my mood well, 4 describes my mood very well). The higher the score, the greater the perception of mood.

Ryff (Psychological Well-Being Scale). It is made up of six dimensions: Self-acceptance, positive relationships, autonomy, mastery of the environment, purpose in life, personal growth. Scale made up of 39 items to which the participants responded using a Likert-type response format with sensitive sensors between 1 (totally disagree) and 6 (totally agree), for a maximum total of 234 points. Scores above 176 are indicative of elevated psychological well-being (BP); between 141 and 175 BP high; between 117 and 140 moderate BP points; and less than 116 BP points low.

The abbreviated 5-factor mindfulness instrument. The FFMQ is a self-report test made up of 39 items, which measures the general tendency to proceed with Mindfulness based on five skills: Observation, Description, Acting Consciously, Absence of Judgment and Absence of Reactivity.

There are two patterns of scoring involved in the Five Facet Mindfulness Test:

Direct Scoring - where the items are scored according to the Likert value (for example 1 would add a score of 1 and 4 adds a value of 4).

Reverse Scoring - where we score the items backward (for example, 1 adds a score of 5, 5 adds a score of 1, 4 would mean a score of 2, and likewise).

Summation of all the direct and reverse items adds up to the total value of the scale.

The responses on the scale are made on a 5-point Likert scale, and the sum of the forward and reverse scoring items gives the total score.

The five subscales of the test provide a meaningful estimate of how aware the respondent is at the moment.
