What is Rejuran?
Rejuran is an injectable skin booster based on polynucleotides, often called PN, derived from salmon DNA. It is designed to support skin repair, improve texture and elasticity, and help with fine lines, enlarged pores and dull skin. Rejuran Healer is the standard version for the face, Rejuran i is made for the delicate skin under the eyes, and Rejuran HB contains lidocaine and hyaluronic acid for added comfort and hydration. Most people need a short series of sessions a few weeks apart.

What is Hongdae like for Rejuran?
Hongdae is a lively area around Hongik University, known for music, cafes and nightlife. Skin clinics here often focus on acne, pores and skin boosters for younger patients, and many offer Rejuran. The area is popular with backpackers and travellers on a budget, and it is very easy to reach from Incheon Airport by the Airport Railroad.

What should you ask before booking?
Ask which Rejuran product will be used and how many cc, whether injections are manual or by device, and how many sessions the doctor suggests. Ask whether numbing cream is applied and how long it needs. A good clinic will explain what to expect afterwards and how to care for your skin while travelling.
How do you plan around downtime?
After Rejuran you may see small bumps at the injection points, mild redness or tiny bruises. Bumps usually settle within a day, and bruises within a few days. Avoid makeup for several hours, and skip saunas, alcohol and hard exercise for a day or two. If you have photos or an event, plan your session at least a few days before.
What affects the cost?
The cost depends on the Rejuran type, the amount in cc, the treatment area, manual or device injection and whether numbing is included. Prices vary between clinics more than between areas, so compare written quotes that list each item.
