This is a procedure note for Rejuran Side Effects: What to Know About Bruising, Swelling, and Recovery at Beomgye(Opening Soon) KKEUT Korean Clinic.

What people considering Rejuran (PN-based skin booster) ask most frequently about is Rejuran side effects.



While they understand the treatment's effects, many hesitate because they are unsure what their face will look like after the treatment.



By understanding the side effects in advance, you can calmly manage the recovery process after the procedure without panicking.







Rejuran Side Effects: Knowing in Advance Makes Them Less Daunting



Rejuran is a skin booster that delivers PN (Polynucleotide) components, extracted and purified from salmon and trout DNA, to the dermal layer.



It is not a treatment that fills volume like a filler. It's about boosting the skin's own regenerative environment.



It activates fibroblasts, induces collagen and elastin production, and also enhances anti-inflammatory effects and moisture retention.



Nowadays, in addition to the brand name Rejuran, PN-based skin boosters are being released under various names. This is because as patents have expired, products based on the same PN components have entered the market.



It is widely used for skin regeneration, elasticity, texture, pore improvement, calming redness and sensitive skin, and even for wrinkles around the eyes.







The three most common Rejuran side effects are swelling, redness, and bruising.



These are natural reactions that occur during the process of injecting the components into the dermal layer, and most are temporary.



Swelling is most noticeable the day after the treatment and rapidly subsides within 1-3 days.



Bruising occurs when capillaries are stimulated as the injection needle passes through. Depending on individual skin characteristics, some people may experience almost no bruising, while others may have light bruising.



Even in severe cases, bruises typically disappear within about a week.



Erythema (redness) is most prominent on the day of the treatment and tends to subside within a few hours to a day.







The extent of Rejuran side effects varies depending on the treatment method.



The manual injection method directly administers the substance into the dermal layer, providing clear effects, but pain and injection marks are relatively noticeable.



Methods like Potenza's pumping tip or MTS channel formation disperse surface stimulation, reducing the risk of nodules, and pain is also relatively less.



The Dermashine (injector) method allows for injection at a uniform depth, which has the advantage of increasing treatment consistency.



Which method is suitable depends on your skin sensitivity and desired effects, so consultation is essential.







Here's a step-by-step breakdown of the recovery timeline.



On the day of the treatment, redness, minor swelling, and injection marks will be clearly visible. It is best to refrain from wearing makeup.



On days 1-2, swelling peaks and then gradually begins to subside. If bruising occurs, it will be most distinct at this point.



On days 3-5, most redness and swelling subside, and the skin surface begins to stabilize.



After about 1 week, most bruising, if any, will have disappeared. You can begin to notice your skin texture gradually improving.







Typically, 3-4 cumulative treatments are recommended at intervals of 2-4 weeks.



Compared to a single treatment, cumulative treatments significantly improve the skin's regenerative environment.



To expedite recovery after the treatment, you should avoid heat stimulation such as saunas, alcohol, and strenuous exercise on the same day.



Adequate moisturizing and diligent application of sunscreen are essential aftercare.



Avoid scrub and peeling products with strong friction until full recovery.



Wash your face gently on the day of the treatment, and it is recommended to use functional products with irritating ingredients only after 2-3 days.







KKEUT Korean Medicine Clinic's Unique PN Treatment Differentiators



KKEUT Korean Medicine Clinic provides a pricing environment that allows for consistent PN (Rejuran) series treatments.



Consistent accumulation is key for PN-based skin boosters. It is not a one-time treatment.



Multiple sessions at 2-4 week intervals are necessary for the skin regeneration effects to become evident.



Low pricing ensures that patients can continue treatments without giving up, and KKEUT Korean Medicine Clinic creates this environment for you.







Embossing Confirmation: Only Possible at KKEUT Korean Medicine Clinic



At KKEUT Korean Medicine Clinic, we ensure that you personally verify the 'embossing' phenomenon in the mirror after the treatment.



Embossing is the phenomenon where the skin rises convexly when the PN component is accurately injected into the dermal layer.



This embossing must appear for the substance to have been properly delivered into the dermal layer.



Simply receiving an injection does not guarantee accurate delivery into the dermal layer.



Receiving treatment at a clinic where you can visually confirm the 'embossing' ensures transparent results.







Kkeut Korean Medicine Clinic is equipped with all three methods: manual injection, Potenza pumping tip, and Dermashine (injector).



The method varies depending on concerns about Rejuran side effects, skin sensitivity, and the desired intensity of the effect.



At Kkeut Korean Medicine Clinic, the most suitable method for the patient's condition is determined after consultation.
