How about the Oh Gangnam General Hospital of DayOne Dermatology in Korea? A real-life review in 2026: location, services, prices, and customer reviews all in one place.
Korea’s DayOne Dermatology – named “Day One” to signify that customers can experience immediate transformation from the moment they enter the clinic.
When it comes to dermatology clinics in Gangnam, Korea, many people think of “expensive” and “assembly-line-style services.” However, the DayOne Dermatology clinic we are going to introduce today is regarded by both locals and international customers as the “king of value for money” – its equipment is on par with that of top luxury hospitals, but the prices are nearly 30% lower.
DayOne Dermatology was established in 2015 and is a specialized dermatology clinic with multiple locations in Seoul. The current branches include:
Korea DayOne Dermatology Gangnam Main Branch (located at Hansung Building, Gangnam-daero, Sujeong-gu)
Korea DayOne Dermatology Gangnam Medi Tower Branch (located at Medi Tower, Gangnam-gu)
Korea DayOne Dermatology Gangnam Station Branch (just 3 minutes’ walk from Exit 10/11 of Gangnam Station)
The branch I am going to review today is the Korea DayOne Dermatology Gangnam Main Branch, which is also the flagship clinic of the entire DayOne network and receives approximately 10,000 customers every year.

### How soon did I see results? How long do the effects last?
>Rejuran doesn’t produce immediate results. The effects appear gradually:
– **1–3 days**: Redness and swelling subside, and the injection sites fade.
– **1–2 weeks**: The skin becomes smoother, and sebum production decreases.
– **2–4 weeks**: The effects reach their peak; the skin looks much brighter, and makeup looks more natural.
– **1–3 months**: The results remain stable. It is recommended to receive 3 treatments in total, with 3–4 weeks between each session for optimal results.

The effects of a single treatment usually last for 2–3 months. If you receive 3 treatments in total, the results can last for more than half a year.
