I found DayOne Clinic while looking for a Korean skin clinic in Gangnam, and the location near Sinnonhyeon Station made it very easy to visit. The clinic itself feels modern and well maintained. I received a Korean skin treatment after consulting with a Korean dermatologist who carefully checked my skin condition and explained the options clearly. The treatment process felt very professional and comfortable. If you’re searching for a trusted Korean skin clinic in Gangnam for proper Korean skin

The hyaluronic acid injections from this place look amazing~ I got my lips and aegyo-sal done, and the results are super natural. Especially the aegyo-sal—it really makes my eyes look bigger. I love it!

A conveniently located dermatology clinic, part of a chain, just steps from the subway station—clean, hygienic, and great value for money.

My visit to this clinic with my wife was one of the best skin care experience. I've been to few clinics but this place top them all!! Reasonable price, very professional client service and super duper technicians and staff! I will always stop at this skin clinic at every Korea visit!

The transportation is very convenient, just right outside Jiangnan Station. The director is young but highly professional, with extensive experience in treating acne. The hospital environment is clean, and the prices are relatively affordable.

Visiting this Korean skin clinic was the best decision for my skin. The Korean dermatologist carefully explained each step, and the Korean skin treatment gave me visible improvements after just one session. Highly recommended!!!!

There are 2 branches in Gangnam and 1 in Hongdae—it\'s a chain dermatology clinic. My friend said it\'s a popular网红 dermatology hospital. When we went together, everyone waited quietly, and during the consultation, we were treated seriously with professional explanations. I got a \"Titan Lift\" treatment.

I really like this kind of decoration style—the sophisticated white and gray tones make the space feel serene and calming, preventing any sense of restlessness.

The dermatology clinic is part of a chain, with an interior layout shaped like the Chinese character \"回.\" The session for the U.S. version of Thermage was quite lengthy, making it feel worth the investment.

The overall environment was clean and comfortable. I went with my best friend, and we were assigned a VIP double room. Director Kim was super handsome, and the Chinese-speaking coordinator was also gentle and beautiful. It was a very satisfying experience, and I’ll definitely come back to this place.

It\'s quite close to Olive Young near Jiangnan Station. I had an appointment for hydration and filler injections, and after the treatment, I went straight to Olive Young to buy some repair masks. The clinic is easy to find, and there are plenty of great places to shop and eat nearby.

I had plump lip injection with Director Kim. My lips look more shapely now. This director is also mainly in charge of injection-related projects.

It\'s also an assembly-line style, but the environment here is much better. They are really good at lip surgeries.

After the consultation, I proceeded with the stem cell procedure. It's a bit expensive, but I think it's because I can inject my own cells and the results are very good ! I feel a lot like I'm younger in terms of my skin condition and age. I've heard so many people comment on how much better my skin looks. Thank you for great treatment.

The clinic is located at the 5th floor of the building. Excellent service, good price. Filler injection and thread lifting by Dr. Kim Joongsoo are the best. Highly recommend!!!
