墨白 Every time I come across posts about medical aesthetics in South Korea, Rejuran PN is almost always mentioned. This restorative hydrogel, famous for its PN ingredients derived from salmon DNA, has evolved faster than most people expected, from its “red box” version to the “black box” version. The Rejuran PN Black Box offered by Newlline Dermatology is currently one of the most highly discussed options in the medical aesthetics community in Taiwan. This article outlines the ingredients and working principles of this product, the key points of its treatment regimen and its cost, as well as how to make a reservation through BeautsGO for those who are interested.
What is the Rejuran PN? What are the differences between it and other versions?
Rejuran Healer is a medical aesthetics injection brand produced by PHARMA RESEARCH in South Korea. Its key ingredient is polynucleotides (PN), which are extracted from the testicular DNA of salmon. The molecular structure of these polynucleotides is similar to that of human DNA, making them less likely to cause rejection reactions in the body. Instead of simply filling voids in the skin, Rejuran Healer works by “repairing” the skin itself – stimulating the natural cell regeneration process and helping to restore the firmness of the dermis over time.
Rejuran’s product line includes several versions: the Red Box (Rejuran Healer), the White Box (Rejuran S), the Black Box (Rejuran Healer Black), and a special formula for the eye area. The Black Box contains a higher concentration of PN and is generally considered a more advanced version, suitable for skin that requires more noticeable firming and repair effects. The recovery period for using this version is also slightly longer.
What is the cost of Rejuran PN at Newlline Dermatology?
The cost of Rejuran PN at Newlline Dermatology starts from 190,000 Korean won. For specific pricing details, a face-to-face consultation is required. The doctor will adjust the treatment plan based on the condition of your skin, the amount of product to be injected, and any additional treatments you may choose. It is recommended that you inform the doctor about your current skin issues during the consultation to obtain a more accurate estimate of the costs.
Who is suitable for using Rejuran PN?
The PN concentration in the black-box version is higher than that in the red-box version, making it suitable for the following groups of people: those who need more noticeable results, those who experience frequent oiliness, those with redness or damaged skin barriers that require repair; those with fine lines and dullness but who do not want to undergo phototherapy directly; and those who wish to accelerate their recovery after laser treatments or dermal resurfacing. However, if the skin is currently in an active inflammatory phase (such as during a breakout), the timing of treatment should be determined by a physician.
The process and recovery period of the Rejuran PN treatment
After the consultation, the doctor will first assess the condition of the skin to determine the appropriate injection site and dosage. Before the procedure, a topical anesthetic ointment will be applied, and after waiting for about 20 minutes, the injection will be administered. The entire process takes approximately 20 to 30 minutes. After the injection, small red spots may appear on the skin surface, but they usually disappear within 24 hours. It is recommended to avoid using irritating skincare products for 3 days after the procedure and to take proper sun protection measures. The effects typically begin to become visible 2 to 4 weeks after the injection. It is suggested to repeat the treatment every 4 weeks, with a total of 3 to 4 sessions constituting one course of treatment.
Common issues when using the Rejuran PN black box
Q: How should I choose between the Rejuran PN Black Box and the Red Box?
The Red Box version is the basic option, suitable for those who are trying this product for the first time or have relatively mild skin issues; the Black Box PN version contains a higher concentration and is more appropriate for those with noticeable fine lines, Pores, or who require more intensive skin repair. To determine which version is more suitable for you, it is recommended to consult a doctor during a face-to-face consultation before making a decision.
Q: Is it very painful to use the Rejuran PN?
Before the injection, an anesthetic is applied first. During the actual injection process, it is mostly described as a mild stinging sensation, nothing unbearable. Pain perception varies from person to person; sensitive areas such as the Forehead may experience more pronounced discomfort, but overall, it is not particularly painful.
Q: How long will it take to see results?
The effects of Rejuran are not immediate, but rather become apparent gradually as cells regenerate. Usually, you will start to notice improvements in skin texture around 2 weeks after the treatment, and the effects become more stable after 4 weeks. After completing a full course of treatment (3 to 4 sessions), the results will last even longer.

Precautions: What should you pay attention to before and after the procedure?
Before the procedure: Avoid taking anticoagulant medications, vitamin E, fish oil, or any other health supplements that may increase the risk of bleeding. It is recommended to stop taking them at least one week in advance. If you have a history of herpes, please inform your doctor in advance so they can assess whether preventive medication is necessary. On the day of the procedure, keep your skin clean and avoid wearing makeup.
After the treatment: Avoid exposure to high-temperature environments for 24 hours (such as hot baths, saunas, or intense exercise); use mild, moisturizing products for 3 days, and steer clear of skincare products containing alcohol or exfoliating ingredients. In the first week following the procedure, increase your sun protection to minimize the impact of ultraviolet rays on your healing skin. If the injection site does not heal within 48 hours or shows signs of significant swelling, it is important to return to the clinic for a check-up.
