SEOUL — Last year in kindergarten, Yang Hye-ji developed her morning routine. Uniform? Check. Homework? Check.
‘‘Makeup makes me look pretty,’’ the 7-year-old said on her second visit to the ShuShu & Sassy beauty spa in Seoul.
She was wrapped in a child-size pink robe and wearing a bunny hairband. Her face was gently touched up with a puff. Her lips got a swipe of pink gloss.

South Korea’s cosmetics industry, known as K-beauty, has become an Asian powerhouse and global phenomenon for its rigorous step-by-step regimens.
But exacting beauty norms also put enormous pressure on South Korean women, making the country one of the world’s centers for plastic surgery. And increasingly, the beauty industry is looking at younger and younger girls.
That is stirring concerns that touch on many core social debates in South Korea: how much a society should value appearance, whether messages about beauty crowd out other aspirations for young girls, and whether it’s right to add even more pressure to an already stress-packed childhood of long school hours and make-or-break exams.
‘‘The shiny cartoon heroines young girls admire are fully made up from head to toe,’’ said Yoon-Kim Ji-yeong, a professor at the Institute of Body and Culture at Seoul’s Konkuk University. ‘‘As they put on the makeup and put on the dress to imitate the characters, girls internalize that a woman’s success is closely associated with beauty.’’
Advertisers are not subtle.
‘‘I watch my mom and I follow her. I am growing up today,’’ a billboard advertisement selling makeup kits for 6-year-olds proclaims, with a photo of a young girl in school uniform applying lipstick.
A YouTube video of a 7-year-old putting on lipstick, titled ‘‘I want to wear makeup like mom,’’ has attracted 4.3 million views, while similar videos show young girls sharing their ‘‘elementary school makeup routine’’ and ‘‘unboxing my Hello Kitty makeup kit.’’
ShuShu Cosmetics is a pioneer in K-beauty’s outreach to children. Started in 2013, it operates 19 boutiques across South Korea, offering ‘‘healthier’’ cosmetics for kids, such as water-soluble nail polish, and nontoxic lip crayons in a range of ‘‘edible’’ colors.
In the spa and beauty parlor, girls ages 4 to 10 can enjoy a spa experience for $25 to $35, featuring a foot bath, a foot and calf massage, a face mask and makeup, and a manicure and pedicure.
‘‘The motto of our beauty spas is that children can connect with their moms while playing with them,’’ said Grace Kim, a manager at ShuShu Cosmetics. ‘‘Our products are safe for pregnant women as well.’’
This is hardly a trend that is exclusive to South Korea. Kylie Jenner has built a cosmetics empire worth an estimated $900 million largely targeting teenage girls, while child beauty vloggers are also popular in the United States and elsewhere.
For decades, academics of all stripes have pored over the impact of pressure on teenagers and young women in the West to conform with unreasonable standards for appearance and body type.
But such concerns in South Korea also now include girls so young they can barely read the packaging on the beauty products aimed at the kindergarten crowd or younger.
South Korea is home to one of the world’s top 10 beauty industries, worth in excess of $10 billion, with per capita cosmetics spending of $45 in 2017, higher than the $37 Americans spend and a global average of $21, according to market research firm Mintel.
It has one of the highest rates of plastic surgery in the world, with one in three women ages 19 to 29 saying they have undergone procedures, especially on their eyelids, according to a Gallup survey. It also has the world’s highest number of plastic surgeons per capita, according to a 2017 study by the International Society of Plastic Surgery.
K-beauty is also becoming popular in the United States. Last month, Representative Alexandria Ocasio-Cortez, Democrat from New York, shared her skin care routine inspired by K-beauty’s elaborate multistep skin care regimen.
The kids’ beauty market is expanding as makeup is promoted as a ‘‘new play culture,’’ said Lee Hwa-jun, an expert on South Korea’s beauty industry at Mintel. ‘‘Cosmetic companies in South Korea are increasingly interested in children as potential new consumers.’’
But some women are already fighting back.
Freelance makeup artist Seo Ga-ram declared that she would refuse clients’ requests to apply cosmetics to child models. ‘‘I found it absolutely bizarre that actual makeup kits have come in place of toys that children play with,’’ she wrote in a Facebook post in May.
