South Korea's cosmetic surgery boom sees 1,200% surge for 'elf ears'

A cosmetic trend known as “elf ears” is driving a new wave of demand in South Korea’s hyper-competitive plastic surgery market, with online queries for the procedure surging 1,200 percent after a K-pop star endorsed a related product.

“It’s quick and has a dramatic result,” said Dr. Jung Gyu-sik, a plastic surgeon in the South Korean city of Daegu who has performed as many as 20 of the procedures in a single day. “It’s now considered as part of anti-aging treatments.”

The procedure involves injecting hyaluronic-acid filler into the ear’s cartilage for about $70 to make it more prominent, creating the illusion of a smaller face—a prized trait in much of East Asia. The trend’s popularity exploded on social media, with a related hashtag accumulating over 780 million views on China’s Weibo and demand for non-invasive ear tape soaring in South Korea.

The phenomenon underscores the relentless search for new revenue streams within South Korea’s saturated plastic surgery industry, a market fueled by medical tourism that drew over 2 million foreign visitors in 2025. For clinics, micro-trends like elf ears represent a crucial way to attract customers in a market where prices for common procedures have been driven down by intense competition.

The elf ear trend first gained widespread attention in China around five years ago before gaining significant traction in South Korea. Its adoption was accelerated last year after Mimi, a member of the K-pop group “Oh My Girl,” revealed she used special tape to achieve the look. Following her admission, queries for “ear filler” on BarbieTalk, a South Korean cosmetic procedure information platform, grew by 1,200 percent.

An Industry Built on Micro-Trends

This demand for niche procedures is a direct byproduct of the economic structure of South Korea's cosmetic surgery sector. The industry’s density is concentrated in Seoul’s “Beauty Belt” neighborhood, which holds more plastic surgery clinics than Los Angeles, Miami, and Rio de Janeiro combined. According to John P. DiMoia of Seoul National University, the industry’s boom began after the country adopted nationalized healthcare in the late 1980s, which pushed many doctors into out-of-pocket specialties.

With an abundance of clinics competing for patients, providers are constantly seeking new, marketable procedures to differentiate themselves. “It would be reductive to frame elf ears as simply an obsession with ears,” said Leem So-yeon, an academic who researches South Korean beauty trends. “Ultimately, it’s a procedure about making the face look smaller. The ears are just the means.”

This strategy appears to be working, particularly with international clients. Foreign visitors seeking medical procedures in South Korea nearly doubled in 2025 from the previous year, with government data showing approximately three-quarters of these visits were for plastic surgery or skincare.

While filler injections are popular, even less invasive and cheaper options are available. Kim Seong-geun, a 32-year-old marketer, purchased a box of elf-ear tape for about $3 after his social media feed was flooded with videos. While he found the initial effect strange, he noted the only drawback was that wearing the tape for extended periods “was more painful than I expected.” The proliferation of such products indicates a broad-based interest that spans different budget levels, further fueling the trend's visibility and the industry's growth.
