South Korean beauty standards prioritize maintaining a youthful appearance rather than looking mature. A combination of clear skin, an even skin complexion, a slim, V-shaped jawline, and pronounced puffy aegyo-sal (fatty, bag-like deposits under the eye—common in children; rare in adults) contributes to a desirable youthful aesthetic and personal presentation. Beauty is often associated with social and economic success in South Korea, particularly in areas such as employment.

The increased influence of South Korean media, such as K-pop, Korean dramas, and advertisements throughout South Korea presents this softer appearance to the public as the desirable norm. Even among men, this softer, more androgynous appearance is preferred in romantic interests and is more evident in the media than among men with traditionally masculine features.

In 2015, a global survey by the International Society of Aesthetic Plastic Surgeons placed South Korea in the top ten of countries who had the highest rate of cosmetic surgeries. South Korea has been described in international media as a "plastic surgery nation", although scholars argue that this idea has been shaped by media narratives and may oversimplify the reality of the industry.

Cultural pressure A study from 2008 determined that 20 percent of young South Korean girls have undergone cosmetic surgery. This is significantly above the average rate in other countries. A 2015 survey from Gallup Korea determined that approximately one-third of South Korean women between ages 19 and 29 had claimed to have had plastic surgery.

In South Korea, immense societal pressure to conform to the community and societal expectations are placed on the individual. This is evident in the theorization of the factors that influence both South Korean men and women to adhere to a strict beauty standard. A study by Lin and Raval from Miami University shows that the pressure for the "perfect" appearance may stem from feelings of inferiority if they perceive themselves as less attractive within their community. The result from this particular study supports the previous evidence from Keong Ja Woo, who analyzed how beauty standards in South Korea, regarding one's height, weight, and facial preference, impacted their chances of employment.Woo, K. J. (2004). The Beauty Complex and the Plastic Surgery Industry. Korea Journal, 44, 52– 82. K-pop idols play and important role in shaping beauty standards in South Korea, often presenting idealized features such as slim bodies, fair skin, and specific facial characteristics. Exposure to these images can influence body image, particularly among adolescent girls, and increase pressure to meet similar standards.

The pressure to uphold a standard of beauty is felt even in the job market. Physical appearance is considered an important factor in hiring and employment opportunities in South Korea. Companies require a photo, height, and sometimes the family background of applicants as a part of the hiring process. Beauty is often seen as a means for socioeconomic success in the rapidly modernized post-war economy of South Korea, which has seen a sluggish job growth rate after its economic boom. Women in particular face greater pressure to conform to beauty standards due to gender expectations within society. This has left South Korea with a highly skilled and educated workforce competing for a short supply of job opportunities and chances for upward social mobility. This competitive job market can increase pressures on individuals to meet appearance standards in order to stand out. Some South Koreans view investments in beauty, such as cosmetic products and medical beauty treatments, such as plastic surgery, dermatology, and cosmetic dentistry, as a means of cultural capital to get an edge over peers for social and economic advancement.

Western beauty ideals have influenced the development of modern beauty standards in South Korea, particularly through globalization and media. The theorization of the impact of Western beauty standards on South Korean society is highly controversial. Some Western authors attribute modern South Korean beauty standards to Western influence, while others point out that Caucasian features are in many cases considered unattractive by South Korean beauty standards, and that South Korean beauty standards portray a traditional ethnic "look" that is seen in pre-colonial Korean art. Western media and advertising have also played a role in shaping beauty standards in South Korea, where the frequent use of Caucasian models in advertisements can reinforce certain appearance ideals. Some studies have reported a higher incidence of body dissatisfaction among South Korean boys and girls than among boys and girls living in the United States, while noting that these studies fail to control for the slimmer and smaller size of South Koreans as compared with Westerners.

In addition, Jung and Lee observed that more models conformed to thin beauty ideals in South Korean magazines than in U.S. magazines.Jung, J., & Lee, Y. J. (2009). Cross-cultural Examination of Women's Fashion and Beauty Magazine Advertisements in the United States and South Korea. Clothing and Textiles Research Journal, 27, 274–286. Higher cultural pressure to conform to thin body ideals in South Korea may be responsible for the higher rate of body dysmorphia and eating disorders among Korean men and women.

Since South Korea has seen a more than 20-fold increase in real per capita income and is currently ranked among the top 20 economies in the world, there has been a parallel increase in visibility for women's rights.Kim, S. Y., Seo, Y. S., & Baek, K. Y. (2014). Face consciousness among South Korean women: A culture-specific extension of objectification theory. Journal of Counseling Psychology, 61(1), 24–36. However, with this growth in visibility and social change for women, Kim et al. argued that it was "immediately accompanied by increases in body dissatisfaction and eating disorders".

Other cultural factors, such as the hardened Confucianism in Korean society, have been quoted as prominent factors. The philosophy of Confucius highly influenced the gender roles and norms in Korea, and some of his teachings have been sustained even through modern Korea. Jung et al. argued that the emphasis on gender roles, with women being submissive and men being dominant, caused a patriarchal society from these philosophical teachings, which may have had an impact on the beauty standard.

Women are more likely to examine and make changes to their bodies and faces in order to adhere to the beauty standards projected by the objectification theory that views women as "objects".Fredrickson, B. L., & Roberts, T. (1997). Objectification theory: Toward understanding women's lived experiences and mental health risks. Psychology of Women Quarterly, 21, 173–206. Lin et al. argued that impractical beauty standards could be caused by highly patriarchal societies that only promote unbending gender roles, which are then reflected by the influence of Confucianism in South Korean history. Lin et al. also argued that another cultural factor such as certain facial features leading to bad luck may incentivize plastic surgery.

Cosmetics

In 2023, South Korea's cosmetic industry was valued at over five trillion South Korean won. In 2015, South Korea exported $2.64 billion of cosmetic goods, $730 million more than in 2014. , South Korea was the 3rd-largest exporter of beauty products and cosmetic goods.

Some of the most popular products used in South Korean beauty are blemish balm (BB) creams, color correction (CC) creams, serums, essences, ampoules, seaweed face masks, and scrubs.

South Korean beauty products contain ingredients not commonly found in Western products, such as snail extract. In 2011, BB cream, previously available only in China, hit the shelves in America, and by 2014, the US market for BB cream was around $164 million.

The ideal for South Korean women is to have "dewy" skin, meaning smooth, hydrated, clear, resilient, and shiny. Chokchok refers to skin that is bouncy and moist; taeng-taeng describes skin that is firm and smooth. The dewy skincare routines are quite different from the Western concept of using makeup to conceal flaws. While Western makeup uses facial contouring to try to change the appearance of one's facial bone structure, South Korean dewy makeup seeks to enhance the skin's appearance, creating a "natural" look.

Plastic surgery

South Korea is often called "plastic surgery capital of the world" due in part to its status as an affordable destination for Chinese, Russian and American cosmetic tourists. "By some accounts, South Korea is the plastic surgery capital of the world. However, this South Korean specialty has become controversial in the last few years. In 2014, the national health ministry reported that 1 in 4 Chinese patients underwent cosmetic surgery. So did 28% of Russians and 23% of Americans." However, a large number of countries in the Western Hemisphere have also been dubbed the "plastic surgery capital of the world". Plastic surgery in South Korea is not as stigmatized as in the west and is even a common graduation gift. The most common plastic surgery among South Koreans is double eyelid surgery and wrinkle removal surgery, whereas Caucasians in Korea tended to get their noses reduced in size, followed by eye surgery. "It was found that the most frequent plastic surgery site for Koreans is 'eyes→wrinkles→nose→chest'." ... "Patients in Western countries such as the United States and Europe and Middle Eastern countries also increased significantly compared to the previous year. According to Banobagi Medical Group, 'rhinoplasty' was the most common, followed by 'eye surgery', 'fat transplant', 'filler botox', and 'contouring'. Western and Middle Eastern patients are said to be too smart and often go to hospitals to trim their large noses."The appeal of common cosmetic procedures among South Koreans are sometimes attributed to Western influence, however many authors reject this view and suggest that they represent the pursuit of a distinctly Korean ethnic "look". "For example, the Asian trends in facial surgery are given as examples of the westernization of global beauty. However, some reject the westernization claim and look to local influences ... Ruth Holiday and colleagues similarly argue that this is not a Western look but a distinctively "Korean look." V-line surgery (jaw and chin reduction) and cheekbone (zygoma) reduction surgeries are used to change the facial contour. These surgeries are especially common amongst celebrities, who are often required to undergo changes in their cheekbones, jaw, and chin, with the ultimate goal of creating an oval face. Some foreigners of Western origin have sought plastic surgery in South Korea to look like South Korean celebrities. "Not known for attracting tourists, South Korea suddenly found that rich foreigners were flocking to Gangnam's 430 clinics to get plastic surgery to look like their favorite Korean celebrities...By 2015 Gangnam expects over 400,000 visitors" "South Koreans get more nip and tucks per capita every year than most anywhere else on Earth. There are endless stories here of crazed fans taking their passion too far, disfiguring their faces with self-administered cooking oil injections, or enduring garish makeovers to turn their seemingly imperfect foreign faces into perfect Korean ones."
