The act of building self-confidence by belittling the appearance of others usually stems from an individual's inferiority complex or insecurity about one's own value. This behavior may be manifested through the following types of speech (it should be noted that these examples are for analytical purposes only, and actual use may cause harm to others)： **1. Direct comparison type** 1. "Do you dare to wear tights at your size? Look at my line. . . " 2. "I don't even do basic skin care. No wonder no one pays attention to you. Unlike me, I take care of it every day." 3. "You can control this hairstyle, but I must be so ugly." **2. Vague negative type** 4. "Not everyone can have the high-end face that is popular now" (implying that the other party does not meet the requirements) 5. "I really envy you that you can go out without makeup. My skin is too sensitive and I have to wear makeup." 6. "I heard that it is popular to be fat recently? No wonder you recently relaxed your body management" **3. Group attack type** 7. "The girls in our circle are all like my legs. It's really rare for you to be like this." 8. "This standard of appearance is normal among boys, but don't ask too much." 9. "It's not easy to maintain my state at the age of 30. Some people are old at 25." **4. False concern type** 10. "Do you want to recommend your medical beauty agency? The one I often go to works very well." 11. "You actually have a good foundation, but you don't know how to dress up. Learn from me." 12. "Have you been under a lot of pressure lately? Your face is so bad, let me recommend health products for you." **Analysis of psychological mechanisms：** This kind of behavior often obtains a short-term sense of superiority through "social comparison theory", and uses "downward comparison" to relieve self-anxiety. Demeaning people may be in appearance anxiety for a long time and maintain their self-esteem by establishing a false "comparative advantage", but in fact they are exposed.： 1. Insufficient self-acceptance 2. Lack of emotional regulation ability 3. Lack of social skills 4. There is cognitive distortion (such as non-black or white thinking) **Response recommendations：** If you encounter such words, you can take： 1. Clarify the boundaries: "It's not appropriate to discuss appearance, let's change the subject" 2. Reverse question: "Do you seem to pay a lot of attention to the appearance of others?" " 3. Self-affirmation: "I am very satisfied with my state" 4. Shift the focus: "I care more about the development of xx abilities than appearance." Healthy self-confidence building should focus on： -Develop sustainable personal abilities -Cultivate growth thinking -Practice self-acceptance -Establish a diversified value evaluation system The essence of this demeaning behavior is to drink poison to quench thirst, which can lead to deterioration of interpersonal relationships and exacerbate self-doubt in the long run. True self-confidence should be based on an objective understanding of one's own value, not on comparison with others.
