This is a guide to skin booster injections compiled by Dr. Choi Byeong-geun of SHINE U Clinic Konkuk (3 minutes walk from Konkuk Univ. Station Exit 1).
This post is a record of a Rejuran procedure with photos. We will briefly summarize the nature of the procedure and what to check before the procedure, along with photos.
What is Rejuran?
Rejuran is a product made from polynucleotide (PN) extracted from salmon DNA, and it is used for the purpose of skin regeneration.
Good things to know before the procedure
- We use small needles to minimize bruising and swelling.
- Avoiding alcohol and smoking for about a week after the procedure may help with recovery.
The suitability and the degree to which one feels the effects may vary from person to person.
If you are curious about the cycle and frequency that are right for your skin condition, you can check with us first through chat consultation.
Reasons to recommend a consultation
The recommended cycle and frequency for Rejuran vary depending on your skin condition and goals. It is difficult to determine a plan that is right for you based on photos alone, so please organize your questions through chat consultation and confirm the direction during a consultation with Dr. Choi Byeong-geun.
