Appearance and Inner Self? ── Does "Aesthetic Change" Really Alter "Personality"?

Introduction: Is "Appearance Shapes Inner Self" True?

In recent years, the options surrounding appearance have exploded, with AI beauty filters, advanced "natural look" makeup, personal color diagnosis, formal/casual attire distinctions, and the generalization of cosmetic medicine. Against this backdrop of social interest, UOL has published an article considering the impact of changes in appearance on "personality." This article will bridge the gap between the latest research and the lived experiences in Japan, using this issue as a starting point. Google News

1. Science Shows "Attire Moves the Mind"—Enclothed Cognition

In psychology, the phenomenon where the "symbolic meaning" and "wearing experience" of clothing systematically change thoughts and behaviors is called enclothed cognition. A classic experiment, where participants who believed they were wearing a "doctor's coat" showed improved attention and task performance, is well-known. In short, attire can temporarily overwrite self-concept and even influence one's approach to tasks (focus, abstraction level, behavioral preferences)—this is the first pillar. ScienceDirect+1

Supplement: Formal Attire Boosts "Abstract Thinking"

Several studies suggest that wearing formal attire enhances abstract and holistic thinking tendencies, making it easier to overview "goals→means." The "power suit" for job hunting, business meetings, and exams serves as a behavioral switch with rationality beyond mere mood. SAGE Journals

2. Makeup Influences "First Impressions"—But It's Not All-Powerful

Makeup has been confirmed to enhance the perception of attractiveness and competence. Etcoff and colleagues at Harvard Medical School demonstrated that makeup raises evaluations of attractiveness and competence in short-term judgments. However, with longer observation times, evaluations of "likability and trust" tend to fluctuate based on the type of makeup—implying that "more is better" is not always the case. PLOS+1

Furthermore, while professional makeup is more effective than self-applied makeup, **the original facial features (individual differences)** have an even greater impact. While makeup can enhance, it is not a "magic" that conceals the base individuality—a realistic conclusion. PLOS

3. The Current State of "Beauty Privilege"—The Halo Effect in the Age of AI Filters

The halo effect (a cognitive bias where attractiveness invites high evaluations of "competence and sincerity") remains in the age of AI beauty filters. A large-scale online experiment in 2024 reported that evaluations of attractiveness, intelligence, and trustworthiness significantly increased before and after filtering the same person. However, it also suggested that filters might weaken the halo effect in certain situations, raising ethical implications. arXiv

4. Does Cosmetic Medicine Enhance "Quality of Life"?—Interpreting the Evidence

There is an increasing number of reviews reporting improvements in self-image, self-esteem, anxiety, depression, and quality of life from aesthetic cosmetic surgery and dermatology. However, some rigorous reviews point out variations in research quality and lack of control groups, making it premature to assert causality. In Japan, decision-making should consider both "expectations and risks."

・On the other hand, strict reviews stating "evidence is still weak"

5. SNS and "Self-Objectification"—To Avoid Being Bound by the Observed Self

Continuous exposure to idealized images on SNS is reported to be associated with decreased body satisfaction. People tend to fall into self-objectification, viewing their bodies as "objects to be observed," which can increase feelings of shame and surveillance. Countermeasures include **curating feeds, controlling exposure, and focusing on functional body appreciation (discussed later)**. WIRED+1

6. Considering the Japanese Context: Gratitude for Function and Recovery of "True Self"

Among Japanese adults, there is a finding that the relationship between age and body acceptance is mediated by the perspective of **"appreciating the body's function". The more one chases the "correct" appearance, the more unstable self-esteem tends to become.Refocusing on "what can be done with this body"** stabilizes self-image, making appearance choices more likely to be "for oneself"—a practical hint.

7. Beauty Pressure in the Workplace—The Boundary Between Manners and Harassment

For example, a survey in Brazil reported that workplace appearance norms impair women's opportunities and self-efficacy, with nearly half experiencing "appearance changes to conform to norms." Implicit dress codes also exist in Japan, but it's necessary to operate without mixing ability evaluation and appearance evaluation, and to establish gender and diversity considerations.

8. Conclusion: It's Not the "Personality" That Changes, But the Mode of Behavior and Cognition

• Short-term (Situation-Dependent): "Aesthetic changes" such as clothing, makeup, hairstyle, filters, and cosmetic medicine can alter mood, self-efficacy, focus, and courage, promoting behavior (e.g., formal attire→increased abstract thinking leading to assertiveness in negotiations). Columbia University

• Long-term (Trait Level): Personality traits like the Big Five are relatively stable. However, as daily behavior patterns accumulate, the "self as habit" is updated, and through feedback from others' reactions→self-concept, one's "character" is gradually shaped.

• Caution: Relying on others' evaluations as "celebratory (halo effect)" can make one vulnerable to setbacks. It's wise to choose appropriate attire for the occasion and purpose while maintaining an axis of "rejoicing in one's own functionality."

9. Practical Guide for Immediate Use (By Japanese Life Scenes)

A. Work, Job Hunting, Presentations

1. Align the purpose→symbolism of attire: Trust, authority→formal, cooperation, affinity→clean×soft.

2. Expand the "comfort zone" that is "easy to play" by one level (e.g., sneakers instead of dress shoes, lighter jackets).

3. Ritualize the self-switch: Activate "work mode" with a set of changing clothes, scent, posture, and music. SAGE Journals

B. Fan Activities, Events, Appearances

1. Clarify roles: Main or supporting role/showing enthusiasm.

2. Design makeup with photos and lighting in mind (counteract T-zone shine, color unevenness, minimize color difference with the neck).

3. Training on how to be photographed: Fix three poses and angles to reduce tension. Note that excessive makeup can lower trust in some situations. PLOS

C. Online Communication, SNS

1. Use filters as "intentional production": Mix "works" and "natural face" instead of constant use to break the chain of self-objectification.

2. Feed hygiene: Reduce continuous exposure to unrealistic images and increase posts sharing functions and skills (performance, cooking, explanations). WIRED

D. Decision-Making in Cosmetic Medicine

1. Verbalize mental objectives: "I want to take a step forward in job hunting," "I want to alleviate a long-standing complex," etc., focusing on "behavioral change."

2. Consult multiple clinics + cooling-off period: Avoid excessive expectations, and confirm both actual data on QOL and satisfaction and limitations. SpringerLink##HTML_TAG
