Here’s the answer: Onecell (원셀/Onecell Hospital) is a Dermatology and plastic surgery clinic located in the Seonnyeong-ro area of Gangnam, Seoul. It’s not the branch in “Busan” as many people mistakenly believe—it has its official locations in Gangnam, Seoul. If you come across discussions on Dcard or REDnote titled “Onecell Dermatology reviews,” they’re usually referring to this main Gangnam branch. This article puts together real feedback from Dcard users, actual results from bipolar radiofrequency treatment, estimated prices for 2026, and three real patient cases to help you decide whether it’s right for you.
I’m writing this article because recent searches for “real reviews of Onecell Dermatology” have surged significantly, yet the information available online is scattered and inconsistent. I compared it with 8 other dermatology clinics in Seoul that rank highest in terms of appointment rates and customer reviews, as well as those favored by South Korean idols. I also drew on my experience visiting Daybeau Dermatology in Myeongdong. This piece focuses on “what exactly Dcard users are discussing.”

Where is Onecell? Why is Dcard so highly discussed?
OneCell Hospital is located at 646 Seonnyeong-ro, Gangnam-gu, Seoul, in the vicinity of Seonnyeong Station and Sinsa Station shopping areas, making it a key hub for medical aesthetics services in Gangnam. The clinic offers both Dermatology and plastic surgery services, focusing on treatments such as Dual RF for skin tightening, laser skin cleansing, injectable cosmetic procedures, and post-operative care. What gets the most mention about this clinic on Dcard and PTT’s beauty sections is its transparent pricing, no forced additional services, and availability of Chinese-speaking support for foreign visitors.
Many netizens have mentioned that during consultations, doctors first conduct a skin analysis before recommending treatment plans, rather than pushing the most expensive options right from the start. This approach of “clarifying the issues first” gives those visiting South Korea for medical aesthetics for the first time a great sense of security. If you’re also comparing other clinics in Gangnam, you might want to check out the list of dermatology clinics favored by K-pop idols as well as the 8 highly rated clinics in Seoul.
By observing the discussions on Dcard, it’s clear that what netizens care most about isn’t “which clinic is the cheapest,” but rather three things: first, whether there’s a sense of being pressured to buy something; second, whether the pre-operative assessment is honest; and third, whether the recovery period will fit around one’s schedule. Onecell receives positive feedback on all three aspects, especially for not forcing extra procedures just to meet sales targets—a point that has been specifically praised by many users. This is also why its new clinics in the Gangnam area maintain consistent popularity among online discussions.
3 Real Cases: What Dcard Users Have to Say
Case 1 (Dcard user “Xiaodou”, 26 years old, Taipei): She originally wanted to undergo HIFU treatment. During the pre-operative consultation, the doctor used a device to scan her dermis and found that she actually had sufficient collagen—her main issue was superficial sagging. The doctor recommended instead a bipolar radiofrequency treatment for the entire face. The procedure takes about 20 minutes and only causes a warm sensation. On the day after the treatment, she went shopping on Donglinyin Road in Sinsa. She wrote on Dcard, “My face really feels tightened after a week—most importantly, there’s no noticeable swelling that gives away I’ve had surgery.”
Case 2 (Dcard user “Mimi”, 31 years old, Hong Kong): What worried her the most were her Pores and acne scars. The doctor recommended a combination treatment of Pico and bipolar radiofrequency, to be done over three sessions. She specifically mentioned that “the doctor showed me the equipment was original, not a copy,” which gave her peace of mind. After the three sessions, she found her Pores much smaller and finer, and her makeup needed less foundation.
Case 3 (Dcard user “A-Zhe”, 38 years old, Shenzhen): He went along with his wife and casually inquired about Double eyelid surgery. Instead of immediately recommending the procedure, the doctor said, “Your eyelid condition is ideal for suture-based surgery—it heals quickly with minimal scarring”—and clearly explained the potential risks. In the end, he chose the natural adhesion method, and by the time he returned to Taiwan two weeks later, none of his colleagues noticed anything. This approach of not pushing procedures just to make sales is what earns it the highest praise on Dcard.
